/**
An instance of `Ember.Application` is the starting point for every Ember
application. It helps to instantiate, initialize and coordinate the many
objects that make up your app.
Each Ember app has one and only one `Ember.Application` object. In fact, the
very first thing you should do in your application is create the instance:
```javascript
window.App = Ember.Application.create();
```
Typically, the application object is the only global variable. All other
classes in your app should be properties on the `Ember.Application` instance,
which highlights its first role: a global namespace.
For example, if you define a view class, it might look like this:
```javascript
App.MyView = Ember.View.extend();
```
By default, calling `Ember.Application.create()` will automatically initialize
your application by calling the `Ember.Application.initialize()` method. If
you need to delay initialization, you can call your app's `deferReadiness()`
method. When you are ready for your app to be initialized, call its
`advanceReadiness()` method.
You can define a `ready` method on the `Ember.Application` instance, which
will be run by Ember when the application is initialized.
Because `Ember.Application` inherits from `Ember.Namespace`, any classes
you create will have useful string representations when calling `toString()`.
See the `Ember.Namespace` documentation for more information.
While you can think of your `Ember.Application` as a container that holds the
other classes in your application, there are several other responsibilities
going on under-the-hood that you may want to understand.
### Event Delegation
Ember uses a technique called _event delegation_. This allows the framework
to set up a global, shared event listener instead of requiring each view to
do it manually. For example, instead of each view registering its own
`mousedown` listener on its associated element, Ember sets up a `mousedown`
listener on the `body`.
If a `mousedown` event occurs, Ember will look at the target of the event and
start walking up the DOM node tree, finding corresponding views and invoking
their `mouseDown` method as it goes.
`Ember.Application` has a number of default events that it listens for, as
well as a mapping from lowercase events to camel-cased view method names. For
example, the `keypress` event causes the `keyPress` method on the view to be
called, the `dblclick` event causes `doubleClick` to be called, and so on.
If there is a bubbling browser event that Ember does not listen for by
default, you can specify custom events and their corresponding view method
names by setting the application's `customEvents` property:
```javascript
App = Ember.Application.create({
customEvents: {
// add support for the paste event
paste: "paste"
}
});
```
By default, the application sets up these event listeners on the document
body. However, in cases where you are embedding an Ember application inside
an existing page, you may want it to set up the listeners on an element
inside the body.
For example, if only events inside a DOM element with the ID of `ember-app`
should be delegated, set your application's `rootElement` property:
```javascript
window.App = Ember.Application.create({
rootElement: '#ember-app'
});
```
The `rootElement` can be either a DOM element or a jQuery-compatible selector
string. Note that *views appended to the DOM outside the root element will
not receive events.* If you specify a custom root element, make sure you only
append views inside it!
To learn more about the advantages of event delegation and the Ember view
layer, and a list of the event listeners that are setup by default, visit the
[Ember View Layer guide](http://emberjs.com/guides/understanding-ember/the-view-layer/#toc_event-delegation).
### Initializers
Libraries on top of Ember can add initializers, like so:
```javascript
Ember.Application.initializer({
name: 'api-adapter',
initialize: function(container, application) {
application.register('api-adapter:main', ApiAdapter);
}
});
```
Initializers provide an opportunity to access the container, which
organizes the different components of an Ember application. Additionally
they provide a chance to access the instantiated application. Beyond
being used for libraries, initializers are also a great way to organize
dependency injection or setup in your own application.
### Routing
In addition to creating your application's router, `Ember.Application` is
also responsible for telling the router when to start routing. Transitions
between routes can be logged with the `LOG_TRANSITIONS` flag, and more
detailed intra-transition logging can be logged with
the `LOG_TRANSITIONS_INTERNAL` flag:
```javascript
window.App = Ember.Application.create({
LOG_TRANSITIONS: true, // basic logging of successful transitions
LOG_TRANSITIONS_INTERNAL: true // detailed logging of all routing steps
});
```
By default, the router will begin trying to translate the current URL into
application state once the browser emits the `DOMContentReady` event. If you
need to defer routing, you can call the application's `deferReadiness()`
method. Once routing can begin, call the `advanceReadiness()` method.
If there is any setup required before routing begins, you can implement a
`ready()` method on your app that will be invoked immediately before routing
begins.

If you would like additional bubbling events to be delegated to your
views, set your `Ember.Application`'s `customEvents` property
to a hash containing the DOM event name as the key and the
corresponding view method name as the value. For example:
```javascript
App = Ember.Application.create({
customEvents: {
// add support for the paste event
paste: "paste"

/**
Registers a factory that can be used for dependency injection (with
`App.inject`) or for service lookup. Each factory is registered with
a full name including two parts: `type:name`.
A simple example:
```javascript
var App = Ember.Application.create();
App.Orange = Ember.Object.extend();
App.register('fruit:favorite', App.Orange);
```
Ember will resolve factories from the `App` namespace automatically.
For example `App.CarsController` will be discovered and returned if
an application requests `controller:cars`.
An example of registering a controller with a non-standard name:
```javascript
var App = Ember.Application.create(),
Session = Ember.Controller.extend();
App.register('controller:session', Session);
// The Session controller can now be treated like a normal controller,
// despite its non-standard name.
App.ApplicationController = Ember.Controller.extend({
needs: ['session']
});
```
Registered factories are **instantiated** by having `create`
called on them. Additionally they are **singletons**, each time
they are looked up they return the same instance.
Some examples modifying that default behavior:
```javascript
var App = Ember.Application.create();
App.Person = Ember.Object.extend();
App.Orange = Ember.Object.extend();
App.Email = Ember.Object.extend();
App.session = Ember.Object.create();
App.register('model:user', App.Person, {singleton: false });
App.register('fruit:favorite', App.Orange);
App.register('communication:main', App.Email, {singleton: false});
App.register('session', App.session, {instantiate: false});
```
@method register
@param fullName {String} type:name (e.g., 'model:user')
@param factory {Function} (e.g., App.Person)
@param options {Object} (optional) disable instantiation or singleton usage
**/
register: function() {
var container = this.__container__;
container.register.apply(container, arguments);
},
/**
Define a dependency injection onto a specific factory or all factories
of a type.
When Ember instantiates a controller, view, or other framework component
it can attach a dependency to that component. This is often used to
provide services to a set of framework components.
An example of providing a session object to all controllers:
```javascript
var App = Ember.Application.create(),
Session = Ember.Object.extend({ isAuthenticated: false });
// A factory must be registered before it can be injected
App.register('session:main', Session);
// Inject 'session:main' onto all factories of the type 'controller'
// with the name 'session'
App.inject('controller', 'session', 'session:main');
App.IndexController = Ember.Controller.extend({
isLoggedIn: Ember.computed.alias('session.isAuthenticated')
});
```
Injections can also be performed on specific factories.
```javascript
App.inject(<full_name or type>, <property name>, <full_name>)
App.inject('route', 'source', 'source:main')
App.inject('route:application', 'email', 'model:email')
```
It is important to note that injections can only be performed on
classes that are instantiated by Ember itself. Instantiating a class
directly (via `create` or `new`) bypasses the dependency injection
system.
Ember-Data instantiates its models in a unique manner, and consequently
injections onto models (or all models) will not work as expected. Injections
on models can be enabled by setting `Ember.MODEL_FACTORY_INJECTIONS`
to `true`.

Reset the application. This is typically used only in tests. It cleans up
the application in the following order:
1. Deactivate existing routes
2. Destroy all objects in the container
3. Create a new application container

Typical Example:
```javascript
var App;
run(function() {

Occasionally you may want to prevent the app from initializing during

to the app becoming ready.
```javascript
var App;
run(function() {
App = Ember.Application.create();
});
module("acceptance test", {

Initializer receives an object which has the following attributes:

This must be a unique name, as trying to register two initializers with the
same name will result in an error.
```javascript
Ember.Application.initializer({
name: 'namedInitializer',
initialize: function(container, application) {
Ember.debug("Running namedInitializer!");
}
});
```
* `before` and `after` are used to ensure that this initializer is ran prior
or after the one identified by the value. This value can be a single string
or an array of strings, referencing the `name` of other initializers.
An example of ordering initializers, we create an initializer named `first`:
```javascript
Ember.Application.initializer({
name: 'first',
initialize: function(container, application) {
Ember.debug("First initializer!");
}
});
// DEBUG: First initializer!
```
We add another initializer named `second`, specifying that it should run
after the initializer named `first`:
```javascript
Ember.Application.initializer({
name: 'second',
after: 'first',
initialize: function(container, application) {
Ember.debug("Second initializer!");
}
});
// DEBUG: First initializer!
// DEBUG: Second initializer!
```
Afterwards we add a further initializer named `pre`, this time specifying
that it should run before the initializer named `first`:
```javascript
Ember.Application.initializer({
name: 'pre',
before: 'first',
initialize: function(container, application) {
Ember.debug("Pre initializer!");
}
});
// DEBUG: Pre initializer!
// DEBUG: First initializer!
// DEBUG: Second initializer!
```
Finally we add an initializer named `post`, specifying it should run after
both the `first` and the `second` initializers:
```javascript
Ember.Application.initializer({
name: 'post',
after: ['first', 'second'],
initialize: function(container, application) {
Ember.debug("Post initializer!");
}
});
// DEBUG: Pre initializer!
// DEBUG: First initializer!
// DEBUG: Second initializer!
// DEBUG: Post initializer!
```
* `initialize` is a callback function that receives two arguments, `container`
and `application` on which you can operate.
Example of using `container` to preload data into the store:
```javascript
Ember.Application.initializer({
name: "preload-data",
initialize: function(container, application) {
var store = container.lookup('store:main');
store.pushPayload(preloadedData);
}
});
```
Example of using `application` to register an adapter:
```javascript
Ember.Application.initializer({

initialize: function(container, application) {
application.register('api-adapter:main', ApiAdapter);
}
});

/**
The DefaultResolver defines the default lookup rules to resolve
container lookups before consulting the container for registered
items:
* templates are looked up on `Ember.TEMPLATES`
* other names are looked up on the application after converting
the name. For example, `controller:post` looks up
`App.PostController` by default.
* there are some nuances (see examples below)
### How Resolving Works
The container calls this object's `resolve` method with the
`fullName` argument.
It first parses the fullName into an object using `parseName`.
Then it checks for the presence of a type-specific instance
method of the form `resolve[Type]` and calls it if it exists.
For example if it was resolving 'template:post', it would call
the `resolveTemplate` method.
Its last resort is to call the `resolveOther` method.
The methods of this object are designed to be easy to override
in a subclass. For example, you could enhance how a template
is resolved like so:
```javascript
App = Ember.Application.create({
Resolver: Ember.DefaultResolver.extend({
resolveTemplate: function(parsedName) {
var resolvedTemplate = this._super(parsedName);
if (resolvedTemplate) { return resolvedTemplate; }
return Ember.TEMPLATES['not_found'];
}
})
});
```
Some examples of how names are resolved:
```
'template:post' //=> Ember.TEMPLATES['post']
'template:posts/byline' //=> Ember.TEMPLATES['posts/byline']
'template:posts.byline' //=> Ember.TEMPLATES['posts/byline']
'template:blogPost' //=> Ember.TEMPLATES['blogPost']
// OR
// Ember.TEMPLATES['blog_post']
'controller:post' //=> App.PostController
'controller:posts.index' //=> App.PostsIndexController
'controller:blog/post' //=> Blog.PostController
'controller:basic' //=> Ember.Controller
'route:post' //=> App.PostRoute
'route:posts.index' //=> App.PostsIndexRoute
'route:blog/post' //=> Blog.PostRoute
'route:basic' //=> Ember.Route
'view:post' //=> App.PostView
'view:posts.index' //=> App.PostsIndexView
'view:blog/post' //=> Blog.PostView
'view:basic' //=> Ember.View
'foo:post' //=> App.PostFoo
'model:post' //=> App.Post
```

```javascript

The above bound helper can be used inside of templates as follows:
```handlebars
{{capitalize name}}
```
In this case, when the `name` property of the template's context changes,
the rendered value of the helper will update to reflect this change.
For more examples of bound helpers, see documentation for
`Ember.Handlebars.registerBoundHelper`.
## Custom view helper example
Assuming a view subclass named `App.CalendarView` were defined, a helper
for rendering instances of this view could be registered as follows:
```javascript
Ember.Handlebars.helper('calendar', App.CalendarView):
```
The above bound helper can be used inside of templates as follows:
```handlebars
{{calendar}}
```
Which is functionally equivalent to:
```handlebars
{{view App.CalendarView}}
```
Options in the helper will be passed to the view in exactly the same
manner as with the `view` helper.

/**
The `{{input}}` helper inserts an HTML `<input>` tag into the template,
with a `type` value of either `text` or `checkbox`. If no `type` is provided,
`text` will be the default value applied. The attributes of `{{input}}`
match those of the native HTML tag as closely as possible for these two types.
## Use as text field
An `{{input}}` with no `type` or a `type` of `text` will render an HTML text input.
The following HTML attributes can be set via the helper:
<table>
<tr><td>`readonly`</td><td>`required`</td><td>`autofocus`</td></tr>
<tr><td>`value`</td><td>`placeholder`</td><td>`disabled`</td></tr>
<tr><td>`size`</td><td>`tabindex`</td><td>`maxlength`</td></tr>
<tr><td>`name`</td><td>`min`</td><td>`max`</td></tr>
<tr><td>`pattern`</td><td>`accept`</td><td>`autocomplete`</td></tr>
<tr><td>`autosave`</td><td>`formaction`</td><td>`formenctype`</td></tr>
<tr><td>`formmethod`</td><td>`formnovalidate`</td><td>`formtarget`</td></tr>
<tr><td>`height`</td><td>`inputmode`</td><td>`multiple`</td></tr>
<tr><td>`step`</td><td>`width`</td><td>`form`</td></tr>
<tr><td>`selectionDirection`</td><td>`spellcheck`</td><td>&nbsp;</td></tr>
</table>
When set to a quoted string, these values will be directly applied to the HTML
element. When left unquoted, these values will be bound to a property on the
template's current rendering context (most typically a controller instance).
## Unbound:
```handlebars
{{input value="http://www.facebook.com"}}
```
```html
<input type="text" value="http://www.facebook.com"/>
```
## Bound:
```javascript
App.ApplicationController = Ember.Controller.extend({
firstName: "Stanley",
entryNotAllowed: true
});
```
```handlebars
{{input type="text" value=firstName disabled=entryNotAllowed size="50"}}
```
```html
<input type="text" value="Stanley" disabled="disabled" size="50"/>
```
## Actions
The helper can send multiple actions based on user events.
The action property defines the action which is send when
the user presses the return key.
```handlebars
{{input action="submit"}}
```
The helper allows some user events to send actions.
* `enter`
* `insert-newline`
* `escape-press`
* `focus-in`
* `focus-out`
* `key-press`
For example, if you desire an action to be sent when the input is blurred,
you only need to setup the action name to the event name property.
```handlebars
{{input focus-in="alertMessage"}}
```
See more about [Text Support Actions](api/classes/Ember.TextField.html)
## Extension
Internally, `{{input type="text"}}` creates an instance of `Ember.TextField`, passing
arguments from the helper to `Ember.TextField`'s `create` method. You can extend the
capabilities of text inputs in your applications by reopening this class. For example,
if you are building a Bootstrap project where `data-*` attributes are used, you
can add one to the `TextField`'s `attributeBindings` property:
```javascript
Ember.TextField.reopen({
attributeBindings: ['data-error']
});
```
Keep in mind when writing `Ember.TextField` subclasses that `Ember.TextField`
itself extends `Ember.Component`, meaning that it does NOT inherit
the `controller` of the parent view.
See more about [Ember components](api/classes/Ember.Component.html)
## Use as checkbox
An `{{input}}` with a `type` of `checkbox` will render an HTML checkbox input.
The following HTML attributes can be set via the helper:
* `checked`
* `disabled`
* `tabindex`
* `indeterminate`
* `name`
* `autofocus`
* `form`
When set to a quoted string, these values will be directly applied to the HTML
element. When left unquoted, these values will be bound to a property on the
template's current rendering context (most typically a controller instance).
## Unbound:
```handlebars
{{input type="checkbox" name="isAdmin"}}
```
```html
<input type="checkbox" name="isAdmin" />
```
## Bound:
```javascript
App.ApplicationController = Ember.Controller.extend({
isAdmin: true
});
```
```handlebars
{{input type="checkbox" checked=isAdmin }}
```
```html
<input type="checkbox" checked="checked" />
```
## Extension
Internally, `{{input type="checkbox"}}` creates an instance of `Ember.Checkbox`, passing
arguments from the helper to `Ember.Checkbox`'s `create` method. You can extend the
capablilties of checkbox inputs in your applications by reopening this class. For example,
if you wanted to add a css class to all checkboxes in your application:
```javascript
Ember.Checkbox.reopen({
classNames: ['my-app-checkbox']
});
```
@method input
@for Ember.Handlebars.helpers
@param {Hash} options
*/
function inputHelper(options) {
Ember.assert('You can only pass attributes to the `input` helper, not arguments', arguments.length < 2);
var hash = options.hash,
types = options.hashTypes,
inputType = hash.type,
onEvent = hash.on;
delete hash.type;
delete hash.on;
if (inputType === 'checkbox') {
Ember.assert("{{input type='checkbox'}} does not support setting `value=someBooleanValue`; you must use `checked=someBooleanValue` instead.", options.hashTypes.value !== 'ID');
return helpers.view.call(this, Checkbox, options);
} else {
if (inputType) {
hash.type = inputType;
}
hash.onEvent = onEvent || 'enter';
return helpers.view.call(this, TextField, options);
}
}
__exports__.inputHelper = inputHelper; /**
`{{textarea}}` inserts a new instance of `<textarea>` tag into the template.
The attributes of `{{textarea}}` match those of the native HTML tags as
closely as possible.
The following HTML attributes can be set:
* `value`
* `name`
* `rows`
* `cols`
* `placeholder`
* `disabled`
* `maxlength`
* `tabindex`
* `selectionEnd`
* `selectionStart`
* `selectionDirection`
* `wrap`
* `readonly`
* `autofocus`
* `form`
* `spellcheck`
* `required`
When set to a quoted string, these value will be directly applied to the HTML
element. When left unquoted, these values will be bound to a property on the
template's current rendering context (most typically a controller instance).
Unbound:
```handlebars
{{textarea value="Lots of static text that ISN'T bound"}}
```
Would result in the following HTML:
```html
<textarea class="ember-text-area">
Lots of static text that ISN'T bound
</textarea>
```
Bound:
In the following example, the `writtenWords` property on `App.ApplicationController`
will be updated live as the user types 'Lots of text that IS bound' into
the text area of their browser's window.
```javascript
App.ApplicationController = Ember.Controller.extend({
writtenWords: "Lots of text that IS bound"
});
```
```handlebars
{{textarea value=writtenWords}}
```
Would result in the following HTML:
```html
<textarea class="ember-text-area">
Lots of text that IS bound
</textarea>
```
If you wanted a one way binding between the text area and a div tag
somewhere else on your screen, you could use `Ember.computed.oneWay`:
```javascript
App.ApplicationController = Ember.Controller.extend({
writtenWords: "Lots of text that IS bound",
outputWrittenWords: Ember.computed.oneWay("writtenWords")
});
```
```handlebars
{{textarea value=writtenWords}}
<div>
{{outputWrittenWords}}
</div>
```
Would result in the following HTML:
```html
<textarea class="ember-text-area">
Lots of text that IS bound
</textarea>
<-- the following div will be updated in real time as you type -->
<div>
Lots of text that IS bound
</div>
```
Finally, this example really shows the power and ease of Ember when two
properties are bound to eachother via `Ember.computed.alias`. Type into
either text area box and they'll both stay in sync. Note that
`Ember.computed.alias` costs more in terms of performance, so only use it when
your really binding in both directions:
```javascript
App.ApplicationController = Ember.Controller.extend({
writtenWords: "Lots of text that IS bound",
twoWayWrittenWords: Ember.computed.alias("writtenWords")
});
```
```handlebars
{{textarea value=writtenWords}}
{{textarea value=twoWayWrittenWords}}
```
```html
<textarea id="ember1" class="ember-text-area">
Lots of text that IS bound
</textarea>
<-- both updated in real time -->
<textarea id="ember2" class="ember-text-area">
Lots of text that IS bound
</textarea>
```
## Actions
The helper can send multiple actions based on user events.
The action property defines the action which is send when
the user presses the return key.
```handlebars
{{input action="submit"}}
```
The helper allows some user events to send actions.
* `enter`
* `insert-newline`
* `escape-press`
* `focus-in`
* `focus-out`
* `key-press`
For example, if you desire an action to be sent when the input is blurred,
you only need to setup the action name to the event name property.
```handlebars
{{textarea focus-in="alertMessage"}}
```
See more about [Text Support Actions](api/classes/Ember.TextArea.html)
## Extension
Internally, `{{textarea}}` creates an instance of `Ember.TextArea`, passing
arguments from the helper to `Ember.TextArea`'s `create` method. You can
extend the capabilities of text areas in your application by reopening this
class. For example, if you are building a Bootstrap project where `data-*`
attributes are used, you can globally add support for a `data-*` attribute
on all `{{textarea}}`s' in your app by reopening `Ember.TextArea` or
`Ember.TextSupport` and adding it to the `attributeBindings` concatenated
property:
```javascript
Ember.TextArea.reopen({
attributeBindings: ['data-error']
});
```
Keep in mind when writing `Ember.TextArea` subclasses that `Ember.TextArea`
itself extends `Ember.Component`, meaning that it does NOT inherit
the `controller` of the parent view.

## Direct manipulation of `checked`
The `checked` attribute of an `Ember.Checkbox` object should always be set
through the Ember object or by interacting with its rendered element
representation via the mouse, keyboard, or touch. Updating the value of the
checkbox via jQuery will result in the checked value of the object and its
element losing synchronization.

/**
The `Ember.Select` view class renders a
[select](https://developer.mozilla.org/en/HTML/Element/select) HTML element,
allowing the user to choose from a list of options.
The text and `value` property of each `<option>` element within the
`<select>` element are populated from the objects in the `Element.Select`'s
`content` property. The underlying data object of the selected `<option>` is
stored in the `Element.Select`'s `value` property.
## The Content Property (array of strings)
The simplest version of an `Ember.Select` takes an array of strings as its
`content` property. The string will be used as both the `value` property and
the inner text of each `<option>` element inside the rendered `<select>`.
Example:
```javascript
App.ApplicationController = Ember.ObjectController.extend({
names: ["Yehuda", "Tom"]
});
```
```handlebars
{{view Ember.Select content=names}}
```
Would result in the following HTML:
```html
<select class="ember-select">
<option value="Yehuda">Yehuda</option>
<option value="Tom">Tom</option>
</select>
```
You can control which `<option>` is selected through the `Ember.Select`'s
`value` property:
```javascript
App.ApplicationController = Ember.ObjectController.extend({
selectedName: 'Tom',
names: ["Yehuda", "Tom"]
});
```
```handlebars
{{view Ember.Select
content=names
value=selectedName
}}
```
Would result in the following HTML with the `<option>` for 'Tom' selected:
```html
<select class="ember-select">
<option value="Yehuda">Yehuda</option>
<option value="Tom" selected="selected">Tom</option>
</select>
```
A user interacting with the rendered `<select>` to choose "Yehuda" would
update the value of `selectedName` to "Yehuda".
## The Content Property (array of Objects)
An `Ember.Select` can also take an array of JavaScript or Ember objects as
its `content` property.
When using objects you need to tell the `Ember.Select` which property should
be accessed on each object to supply the `value` attribute of the `<option>`
and which property should be used to supply the element text.
The `optionValuePath` option is used to specify the path on each object to
the desired property for the `value` attribute. The `optionLabelPath`
specifies the path on each object to the desired property for the
element's text. Both paths must reference each object itself as `content`:
```javascript
App.ApplicationController = Ember.ObjectController.extend({
programmers: [
{firstName: "Yehuda", id: 1},
{firstName: "Tom", id: 2}
]
});
```
```handlebars
{{view Ember.Select
content=programmers
optionValuePath="content.id"
optionLabelPath="content.firstName"}}
```
Would result in the following HTML:
```html
<select class="ember-select">
<option value="1">Yehuda</option>
<option value="2">Tom</option>
</select>
```
The `value` attribute of the selected `<option>` within an `Ember.Select`
can be bound to a property on another object:
```javascript
App.ApplicationController = Ember.ObjectController.extend({
programmers: [
{firstName: "Yehuda", id: 1},
{firstName: "Tom", id: 2}
],
currentProgrammer: {
id: 2
}
});
```
```handlebars
{{view Ember.Select
content=programmers
optionValuePath="content.id"
optionLabelPath="content.firstName"
value=currentProgrammer.id}}
```
Would result in the following HTML with a selected option:
```html
<select class="ember-select">
<option value="1">Yehuda</option>
<option value="2" selected="selected">Tom</option>
</select>
```
Interacting with the rendered element by selecting the first option
('Yehuda') will update the `id` of `currentProgrammer`
to match the `value` property of the newly selected `<option>`.
Alternatively, you can control selection through the underlying objects
used to render each object by binding the `selection` option. When the selected
`<option>` is changed, the property path provided to `selection`
will be updated to match the content object of the rendered `<option>`
element:
```javascript
var yehuda = {firstName: "Yehuda", id: 1, bff4eva: 'tom'}
var tom = {firstName: "Tom", id: 2, bff4eva: 'yehuda'};
App.ApplicationController = Ember.ObjectController.extend({
selectedPerson: tom,
programmers: [
yehuda,
tom
]
});
```
```handlebars
{{view Ember.Select
content=programmers
optionValuePath="content.id"
optionLabelPath="content.firstName"
selection=selectedPerson}}
```
Would result in the following HTML with a selected option:
```html
<select class="ember-select">
<option value="1">Yehuda</option>
<option value="2" selected="selected">Tom</option>
</select>
```
Interacting with the rendered element by selecting the first option
('Yehuda') will update the `selectedPerson` to match the object of
the newly selected `<option>`. In this case it is the first object
in the `programmers`
## Supplying a Prompt
A `null` value for the `Ember.Select`'s `value` or `selection` property
results in there being no `<option>` with a `selected` attribute:
```javascript
App.ApplicationController = Ember.ObjectController.extend({
selectedProgrammer: null,
programmers: [
"Yehuda",
"Tom"
]
});
```
``` handlebars
{{view Ember.Select
content=programmers
value=selectedProgrammer
}}
```
Would result in the following HTML:
```html
<select class="ember-select">
<option value="Yehuda">Yehuda</option>
<option value="Tom">Tom</option>
</select>
```
Although `selectedProgrammer` is `null` and no `<option>`
has a `selected` attribute the rendered HTML will display the
first item as though it were selected. You can supply a string
value for the `Ember.Select` to display when there is no selection
with the `prompt` option:
```javascript
App.ApplicationController = Ember.ObjectController.extend({
selectedProgrammer: null,
programmers: [
"Yehuda",
"Tom"
]
});
```
```handlebars
{{view Ember.Select
content=programmers
value=selectedProgrammer
prompt="Please select a name"
}}
```
Would result in the following HTML:
```html
<select class="ember-select">
<option>Please select a name</option>
<option value="Yehuda">Yehuda</option>
<option value="Tom">Tom</option>
</select>
```

Register a bound handlebars helper. Bound helpers behave similarly to regular
handlebars helpers, with the added ability to re-render when the underlying data
changes.
## Simple example
```javascript
Ember.Handlebars.registerBoundHelper('capitalize', function(value) {
return Ember.String.capitalize(value);
});
```
The above bound helper can be used inside of templates as follows:
```handlebars
{{capitalize name}}
```
In this case, when the `name` property of the template's context changes,
the rendered value of the helper will update to reflect this change.
## Example with options
Like normal handlebars helpers, bound helpers have access to the options
passed into the helper call.
```javascript
Ember.Handlebars.registerBoundHelper('repeat', function(value, options) {
var count = options.hash.count;
var a = [];
while(a.length < count) {
a.push(value);
}
return a.join('');
});
```
This helper could be used in a template as follows:
```handlebars
{{repeat text count=3}}
```
## Example with bound options
Bound hash options are also supported. Example:
```handlebars
{{repeat text count=numRepeats}}
```
In this example, count will be bound to the value of
the `numRepeats` property on the context. If that property
changes, the helper will be re-rendered.
## Example with extra dependencies
The `Ember.Handlebars.registerBoundHelper` method takes a variable length
third parameter which indicates extra dependencies on the passed in value.
This allows the handlebars helper to update when these dependencies change.
```javascript
Ember.Handlebars.registerBoundHelper('capitalizeName', function(value) {
return value.get('name').toUpperCase();
}, 'name');
```
## Example with multiple bound properties
`Ember.Handlebars.registerBoundHelper` supports binding to
multiple properties, e.g.:
```javascript
Ember.Handlebars.registerBoundHelper('concatenate', function() {
var values = Array.prototype.slice.call(arguments, 0, -1);
return values.join('||');
});
```
Which allows for template syntax such as `{{concatenate prop1 prop2}}` or
`{{concatenate prop1 prop2 prop3}}`. If any of the properties change,
the helper will re-render. Note that dependency keys cannot be
using in conjunction with multi-property helpers, since it is ambiguous
which property the dependent keys would belong to.
## Use with unbound helper
The `{{unbound}}` helper can be used with bound helper invocations
to render them in their unbound form, e.g.
```handlebars
{{unbound capitalize name}}
```
In this example, if the name property changes, the helper
will not re-render.
## Use with blocks not supported
Bound helpers do not support use with Handlebars blocks or
the addition of child views of any kind.

/**
Use the `{{with}}` helper when you want to scope context. Take the following code as an example:
```handlebars
<h5>{{user.name}}</h5>
<div class="role">
<h6>{{user.role.label}}</h6>
<span class="role-id">{{user.role.id}}</span>
<p class="role-desc">{{user.role.description}}</p>
</div>
```
`{{with}}` can be our best friend in these cases,
instead of writing `user.role.*` over and over, we use `{{#with user.role}}`.
Now the context within the `{{#with}} .. {{/with}}` block is `user.role` so you can do the following:
```handlebars
<h5>{{user.name}}</h5>
<div class="role">
{{#with user.role}}
<h6>{{label}}</h6>
<span class="role-id">{{id}}</span>
<p class="role-desc">{{description}}</p>
{{/with}}
</div>
```
### `as` operator
This operator aliases the scope to a new name. It's helpful for semantic clarity and to retain
default scope or to reference from another `{{with}}` block.
```handlebars
// posts might not be
{{#with user.posts as blogPosts}}
<div class="notice">
There are {{blogPosts.length}} blog posts written by {{user.name}}.
</div>
{{#each post in blogPosts}}
<li>{{post.title}}</li>
{{/each}}
{{/with}}
```
Without the `as` operator, it would be impossible to reference `user.name` in the example above.
NOTE: The alias should not reuse a name from the bound property path.
For example: `{{#with foo.bar as foo}}` is not supported because it attempts to alias using
the first part of the property path, `foo`. Instead, use `{{#with foo.bar as baz}}`.
### `controller` option
Adding `controller='something'` instructs the `{{with}}` helper to create and use an instance of
the specified controller with the new context as its content.
This is very similar to using an `itemController` option with the `{{each}}` helper.
```handlebars
{{#with users.posts controller='userBlogPosts'}}
{{!- The current context is wrapped in our controller instance }}
{{/with}}
```
In the above example, the template provided to the `{{with}}` block is now wrapped in the
`userBlogPost` controller, which provides a very elegant way to decorate the context with custom
functions/properties.

/**
`bind-attr` allows you to create a binding between DOM element attributes and
Ember objects. For example:
```handlebars
<img {{bind-attr src="imageUrl" alt="imageTitle"}}>
```
The above handlebars template will fill the `<img>`'s `src` attribute will
the value of the property referenced with `"imageUrl"` and its `alt`
attribute with the value of the property referenced with `"imageTitle"`.
If the rendering context of this template is the following object:
```javascript
{
imageUrl: 'http://lolcats.info/haz-a-funny',
imageTitle: 'A humorous image of a cat'
}
```
The resulting HTML output will be:
```html
<img src="http://lolcats.info/haz-a-funny" alt="A humorous image of a cat">
```
`bind-attr` cannot redeclare existing DOM element attributes. The use of `src`
in the following `bind-attr` example will be ignored and the hard coded value
of `src="/failwhale.gif"` will take precedence:
```handlebars
<img src="/failwhale.gif" {{bind-attr src="imageUrl" alt="imageTitle"}}>
```
### `bind-attr` and the `class` attribute
`bind-attr` supports a special syntax for handling a number of cases unique
to the `class` DOM element attribute. The `class` attribute combines
multiple discrete values into a single attribute as a space-delimited
list of strings. Each string can be:
* a string return value of an object's property.
* a boolean return value of an object's property
* a hard-coded value
A string return value works identically to other uses of `bind-attr`. The
return value of the property will become the value of the attribute. For
example, the following view and template:
```javascript
AView = View.extend({
someProperty: function() {
return "aValue";
}.property()
})
```
```handlebars
<img {{bind-attr class="view.someProperty}}>
```
Result in the following rendered output:
```html
<img class="aValue">
```
A boolean return value will insert a specified class name if the property
returns `true` and remove the class name if the property returns `false`.
A class name is provided via the syntax
`somePropertyName:class-name-if-true`.
```javascript
AView = View.extend({
someBool: true
})
```
```handlebars
<img {{bind-attr class="view.someBool:class-name-if-true"}}>
```
Result in the following rendered output:
```html
<img class="class-name-if-true">
```
An additional section of the binding can be provided if you want to
replace the existing class instead of removing it when the boolean
value changes:
```handlebars
<img {{bind-attr class="view.someBool:class-name-if-true:class-name-if-false"}}>
```
A hard-coded value can be used by prepending `:` to the desired
class name: `:class-name-to-always-apply`.
```handlebars
<img {{bind-attr class=":class-name-to-always-apply"}}>
```
Results in the following rendered output:
```html
<img class="class-name-to-always-apply">
```
All three strategies - string return value, boolean return value, and
hard-coded value – can be combined in a single declaration:
```handlebars
<img {{bind-attr class=":class-name-to-always-apply view.someBool:class-name-if-true view.someProperty"}}>
```

/**
`{{collection}}` is a `Ember.Handlebars` helper for adding instances of
`Ember.CollectionView` to a template. See [Ember.CollectionView](/api/classes/Ember.CollectionView.html)
for additional information on how a `CollectionView` functions.
`{{collection}}`'s primary use is as a block helper with a `contentBinding`
option pointing towards an `Ember.Array`-compatible object. An `Ember.View`
instance will be created for each item in its `content` property. Each view
will have its own `content` property set to the appropriate item in the
collection.
The provided block will be applied as the template for each item's view.
Given an empty `<body>` the following template:
```handlebars
{{#collection contentBinding="App.items"}}
Hi {{view.content.name}}
{{/collection}}
```
And the following application code
```javascript
App = Ember.Application.create()
App.items = [
Ember.Object.create({name: 'Dave'}),
Ember.Object.create({name: 'Mary'}),
Ember.Object.create({name: 'Sara'})
]
```
Will result in the HTML structure below
```html
<div class="ember-view">
<div class="ember-view">Hi Dave</div>
<div class="ember-view">Hi Mary</div>
<div class="ember-view">Hi Sara</div>
</div>
```
### Blockless use in a collection
If you provide an `itemViewClass` option that has its own `template` you can
omit the block.
The following template:
```handlebars
{{collection contentBinding="App.items" itemViewClass="App.AnItemView"}}
```
And application code
```javascript
App = Ember.Application.create();
App.items = [
Ember.Object.create({name: 'Dave'}),
Ember.Object.create({name: 'Mary'}),
Ember.Object.create({name: 'Sara'})
];
App.AnItemView = Ember.View.extend({
template: Ember.Handlebars.compile("Greetings {{view.content.name}}")
});
```
Will result in the HTML structure below
```html
<div class="ember-view">
<div class="ember-view">Greetings Dave</div>
<div class="ember-view">Greetings Mary</div>
<div class="ember-view">Greetings Sara</div>
</div>
```
### Specifying a CollectionView subclass
By default the `{{collection}}` helper will create an instance of
`Ember.CollectionView`. You can supply a `Ember.CollectionView` subclass to
the helper by passing it as the first argument:
```handlebars
{{#collection App.MyCustomCollectionClass contentBinding="App.items"}}
Hi {{view.content.name}}
{{/collection}}
```
### Forwarded `item.*`-named Options
As with the `{{view}}`, helper options passed to the `{{collection}}` will be
set on the resulting `Ember.CollectionView` as properties. Additionally,
options prefixed with `item` will be applied to the views rendered for each
item (note the camelcasing):
```handlebars
{{#collection contentBinding="App.items"
itemTagName="p"
itemClassNames="greeting"}}
Howdy {{view.content.name}}
{{/collection}}
```
Will result in the following HTML structure:
```html
<div class="ember-view">
<p class="ember-view greeting">Howdy Dave</p>
<p class="ember-view greeting">Howdy Mary</p>
<p class="ember-view greeting">Howdy Sara</p>
</div>

/**
The `{{#each}}` helper loops over elements in a collection, rendering its
block once for each item. It is an extension of the base Handlebars `{{#each}}`
helper:
```javascript
Developers = [{name: 'Yehuda'},{name: 'Tom'}, {name: 'Paul'}];
```
```handlebars
{{#each Developers}}
{{name}}
{{/each}}
```
`{{each}}` supports an alternative syntax with element naming:
```handlebars
{{#each person in Developers}}
{{person.name}}
{{/each}}
```
When looping over objects that do not have properties, `{{this}}` can be used
to render the object:
```javascript
DeveloperNames = ['Yehuda', 'Tom', 'Paul']
```
```handlebars
{{#each DeveloperNames}}
{{this}}
{{/each}}
```
### {{else}} condition
`{{#each}}` can have a matching `{{else}}`. The contents of this block will render
if the collection is empty.
```
{{#each person in Developers}}
{{person.name}}
{{else}}
<p>Sorry, nobody is available for this task.</p>
{{/each}}
```
### Specifying a View class for items
If you provide an `itemViewClass` option that references a view class
with its own `template` you can omit the block.
The following template:
```handlebars
{{#view App.MyView }}
{{each view.items itemViewClass="App.AnItemView"}}
{{/view}}
```
And application code
```javascript
App = Ember.Application.create({
MyView: Ember.View.extend({
items: [
Ember.Object.create({name: 'Dave'}),
Ember.Object.create({name: 'Mary'}),
Ember.Object.create({name: 'Sara'})
]
})
});
App.AnItemView = Ember.View.extend({
template: Ember.Handlebars.compile("Greetings {{name}}")
});
```
Will result in the HTML structure below
```html
<div class="ember-view">
<div class="ember-view">Greetings Dave</div>
<div class="ember-view">Greetings Mary</div>
<div class="ember-view">Greetings Sara</div>
</div>
```
If an `itemViewClass` is defined on the helper, and therefore the helper is not
being used as a block, an `emptyViewClass` can also be provided optionally.
The `emptyViewClass` will match the behavior of the `{{else}}` condition
described above. That is, the `emptyViewClass` will render if the collection
is empty.
### Representing each item with a Controller.
By default the controller lookup within an `{{#each}}` block will be
the controller of the template where the `{{#each}}` was used. If each
item needs to be presented by a custom controller you can provide a
`itemController` option which references a controller by lookup name.
Each item in the loop will be wrapped in an instance of this controller
and the item itself will be set to the `model` property of that controller.
This is useful in cases where properties of model objects need transformation
or synthesis for display:
```javascript
App.DeveloperController = Ember.ObjectController.extend({
isAvailableForHire: function() {
return !this.get('model.isEmployed') && this.get('model.isSeekingWork');
}.property('isEmployed', 'isSeekingWork')
})
```
```handlebars
{{#each person in developers itemController="developer"}}
{{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}}
{{/each}}
```
Each itemController will receive a reference to the current controller as
a `parentController` property.
### (Experimental) Grouped Each
When used in conjunction with the experimental [group helper](https://github.com/emberjs/group-helper),
you can inform Handlebars to re-render an entire group of items instead of
re-rendering them one at a time (in the event that they are changed en masse
or an item is added/removed).
```handlebars
{{#group}}
{{#each people}}
{{firstName}} {{lastName}}
{{/each}}
{{/group}}
```
This can be faster than the normal way that Handlebars re-renders items
in some cases.
If for some reason you have a group with more than one `#each`, you can make
one of the collections be updated in normal (non-grouped) fashion by setting
the option `groupedRows=true` (counter-intuitive, I know).
For example,
```handlebars
{{dealershipName}}
{{#group}}
{{#each dealers}}
{{firstName}} {{lastName}}
{{/each}}
{{#each car in cars groupedRows=true}}
{{car.make}} {{car.model}} {{car.color}}
{{/each}}
{{/group}}
```
Any change to `dealershipName` or the `dealers` collection will cause the
entire group to be re-rendered. However, changes to the `cars` collection
will be re-rendered individually (as normal).
Note that `group` behavior is also disabled by specifying an `itemViewClass`.

The `partial` helper renders another template without
changing the template context:
```handlebars
{{foo}}
{{partial "nav"}}
```
The above example template will render a template named
"_nav", which has the same context as the parent template
it's rendered into, so if the "_nav" template also referenced
`{{foo}}`, it would print the same thing as the `{{foo}}`
in the above example.
If a "_nav" template isn't found, the `partial` helper will
fall back to a template named "nav".
## Bound template names
The parameter supplied to `partial` can also be a path
to a property containing a template name, e.g.:
```handlebars
{{partial someTemplateName}}
```
The above example will look up the value of `someTemplateName`
on the template context (e.g. a controller) and use that
value as the name of the template to render. If the resolved
value is falsy, nothing will be rendered. If `someTemplateName`
changes, the partial will be re-rendered using the new template
name.
## Setting the partial's context with `with`
The `partial` helper can be used in conjunction with the `with`
helper to set a context that will be used by the partial:
```handlebars
{{#with currentUser}}
{{partial "user_info"}}
{{/with}}
```

`template` allows you to render a template from inside another template.
This allows you to re-use the same template in multiple places. For example:

{{#with loggedInUser}}
Last Login: {{lastLogin}}
User Info: {{template "user_info"}}

/**
`{{view}}` inserts a new instance of an `Ember.View` into a template passing its
options to the `Ember.View`'s `create` method and using the supplied block as
the view's own template.
An empty `<body>` and the following template:
```handlebars
A span:
{{#view tagName="span"}}
hello.
{{/view}}
```
Will result in HTML structure:
```html
<body>
<!-- Note: the handlebars template script
also results in a rendered Ember.View
which is the outer <div> here -->
<div class="ember-view">
A span:
<span id="ember1" class="ember-view">
Hello.
</span>
</div>
</body>
```
### `parentView` setting
The `parentView` property of the new `Ember.View` instance created through
`{{view}}` will be set to the `Ember.View` instance of the template where
`{{view}}` was called.
```javascript
aView = Ember.View.create({
template: Ember.Handlebars.compile("{{#view}} my parent: {{parentView.elementId}} {{/view}}")
});
aView.appendTo('body');
```
Will result in HTML structure:
```html
<div id="ember1" class="ember-view">
<div id="ember2" class="ember-view">
my parent: ember1
</div>
</div>
```
### Setting CSS id and class attributes
The HTML `id` attribute can be set on the `{{view}}`'s resulting element with
the `id` option. This option will _not_ be passed to `Ember.View.create`.
```handlebars
{{#view tagName="span" id="a-custom-id"}}
hello.
{{/view}}
```
Results in the following HTML structure:
```html
<div class="ember-view">
<span id="a-custom-id" class="ember-view">
hello.
</span>
</div>
```
The HTML `class` attribute can be set on the `{{view}}`'s resulting element
with the `class` or `classNameBindings` options. The `class` option will
directly set the CSS `class` attribute and will not be passed to
`Ember.View.create`. `classNameBindings` will be passed to `create` and use
`Ember.View`'s class name binding functionality:
```handlebars
{{#view tagName="span" class="a-custom-class"}}
hello.
{{/view}}
```
Results in the following HTML structure:
```html
<div class="ember-view">
<span id="ember2" class="ember-view a-custom-class">
hello.
</span>
</div>
```
### Supplying a different view class
`{{view}}` can take an optional first argument before its supplied options to
specify a path to a custom view class.
```handlebars
{{#view "MyApp.CustomView"}}
hello.
{{/view}}
```
The first argument can also be a relative path accessible from the current
context.
```javascript
MyApp = Ember.Application.create({});
MyApp.OuterView = Ember.View.extend({
innerViewClass: Ember.View.extend({
classNames: ['a-custom-view-class-as-property']
}),
template: Ember.Handlebars.compile('{{#view "view.innerViewClass"}} hi {{/view}}')
});
MyApp.OuterView.create().appendTo('body');
```
Will result in the following HTML:
```html
<div id="ember1" class="ember-view">
<div id="ember2" class="ember-view a-custom-view-class-as-property">
hi
</div>
</div>
```
### Blockless use
If you supply a custom `Ember.View` subclass that specifies its own template
or provide a `templateName` option to `{{view}}` it can be used without
supplying a block. Attempts to use both a `templateName` option and supply a
block will throw an error.
```handlebars
{{view "MyApp.ViewWithATemplateDefined"}}
```
### `viewName` property
You can supply a `viewName` option to `{{view}}`. The `Ember.View` instance
will be referenced as a property of its parent view by this name.
```javascript
aView = Ember.View.create({
template: Ember.Handlebars.compile('{{#view viewName="aChildByName"}} hi {{/view}}')
});
aView.appendTo('body');
aView.get('aChildByName') // the instance of Ember.View created by {{view}} helper
```
@method view

if (path && path.data && path.data.isRenderData) {
options = path;
Ember.assert('{{view}} helper requires parent view to have a container but none was found. This usually happens when you are manually-managing views.', !!options.data.view.container);

`{{yield}}` denotes an area of a template that will be rendered inside
of another template. It has two main uses:
### Use with `layout`
When used in a Handlebars template that is assigned to an `Ember.View`
instance's `layout` property Ember will render the layout template first,
inserting the view's own rendered output at the `{{yield}}` location.
An empty `<body>` and the following application code:
```javascript
AView = Ember.View.extend({
classNames: ['a-view-with-layout'],
layout: Ember.Handlebars.compile('<div class="wrapper">{{yield}}</div>'),
template: Ember.Handlebars.compile('<span>I am wrapped</span>')
});
aView = AView.create();
aView.appendTo('body');
```
Will result in the following HTML output:
```html
<body>
<div class='ember-view a-view-with-layout'>
<div class="wrapper">
<span>I am wrapped</span>
</div>
</div>
</body>
```
The `yield` helper cannot be used outside of a template assigned to an
`Ember.View`'s `layout` property and will throw an error if attempted.
```javascript
BView = Ember.View.extend({
classNames: ['a-view-with-layout'],
template: Ember.Handlebars.compile('{{yield}}')
});
bView = BView.create();
bView.appendTo('body');
// throws
// Uncaught Error: assertion failed:
// You called yield in a template that was not a layout
```
### Use with Ember.Component
When designing components `{{yield}}` is used to denote where, inside the component's
template, an optional block passed to the component should render:
```handlebars
<!-- application.hbs -->
{{#labeled-textfield value=someProperty}}
First name:
{{/labeled-textfield}}
```
```handlebars
<!-- components/labeled-textfield.hbs -->
<label>
{{yield}} {{input value=value}}
</label>
```
Result:
```html
<label>
First name: <input type="text" />
</label>

/**
An `Ember.Binding` connects the properties of two objects so that whenever
the value of one property changes, the other property will be changed also.
## Automatic Creation of Bindings with `/^*Binding/`-named Properties
You do not usually create Binding objects directly but instead describe
bindings in your class or object definition using automatic binding
detection.
Properties ending in a `Binding` suffix will be converted to `Ember.Binding`
instances. The value of this property should be a string representing a path
to another object or a custom binding instanced created using Binding helpers
(see "One Way Bindings"):
```
valueBinding: "MyApp.someController.title"
```
This will create a binding from `MyApp.someController.title` to the `value`
property of your object instance automatically. Now the two values will be
kept in sync.
## One Way Bindings
One especially useful binding customization you can use is the `oneWay()`
helper. This helper tells Ember that you are only interested in
receiving changes on the object you are binding from. For example, if you
are binding to a preference and you want to be notified if the preference
has changed, but your object will not be changing the preference itself, you
could do:
```
bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles")
```
This way if the value of `MyApp.preferencesController.bigTitles` changes the
`bigTitles` property of your object will change also. However, if you
change the value of your `bigTitles` property, it will not update the
`preferencesController`.
One way bindings are almost twice as fast to setup and twice as fast to
execute because the binding only has to worry about changes to one side.
You should consider using one way bindings anytime you have an object that
may be created frequently and you do not intend to change a property; only
to monitor it for changes (such as in the example above).
## Adding Bindings Manually
All of the examples above show you how to configure a custom binding, but the
result of these customizations will be a binding template, not a fully active
Binding instance. The binding will actually become active only when you
instantiate the object the binding belongs to. It is useful however, to
understand what actually happens when the binding is activated.
For a binding to function it must have at least a `from` property and a `to`
property. The `from` property path points to the object/key that you want to
bind from while the `to` path points to the object/key you want to bind to.
When you define a custom binding, you are usually describing the property
you want to bind from (such as `MyApp.someController.value` in the examples
above). When your object is created, it will automatically assign the value
you want to bind `to` based on the name of your binding key. In the
examples above, during init, Ember objects will effectively call
something like this on your binding:
```javascript
binding = Ember.Binding.from(this.valueBinding).to("value");
```
This creates a new binding instance based on the template you provide, and
sets the to path to the `value` property of the new object. Now that the
binding is fully configured with a `from` and a `to`, it simply needs to be
connected to become active. This is done through the `connect()` method:
```javascript
binding.connect(this);
```
Note that when you connect a binding you pass the object you want it to be
connected to. This object will be used as the root for both the from and
to side of the binding when inspecting relative paths. This allows the
binding to be automatically inherited by subclassed objects as well.
Now that the binding is connected, it will observe both the from and to side
and relay changes.
If you ever needed to do so (you almost never will, but it is useful to
understand this anyway), you could manually create an active binding by
using the `Ember.bind()` helper method. (This is the same method used by
to setup your bindings on objects):
```javascript
Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value");
```
Both of these code fragments have the same effect as doing the most friendly
form of binding creation like so:
```javascript
MyApp.anotherObject = Ember.Object.create({
valueBinding: "MyApp.someController.value",
// OTHER CODE FOR THIS OBJECT...
});
```
Ember's built in binding creation method makes it easy to automatically
create bindings for you. You should always use the highest-level APIs
available, even if you understand how it works underneath.

/**
A computed property transforms an objects function into a property.
By default the function backing the computed property will only be called
once and the result will be cached. You can specify various properties
that your computed property is dependent on. This will force the cached
result to be recomputed if the dependencies are modified.
In the following example we declare a computed property (by calling
`.property()` on the fullName function) and setup the properties
dependencies (depending on firstName and lastName). The fullName function
will be called once (regardless of how many times it is accessed) as long
as it's dependencies have not been changed. Once firstName or lastName are updated
any future calls (or anything bound) to fullName will incorporate the new
values.
```javascript
var Person = Ember.Object.extend({
// these will be supplied by `create`
firstName: null,
lastName: null,
fullName: function() {
var firstName = this.get('firstName');
var lastName = this.get('lastName');
return firstName + ' ' + lastName;
}.property('firstName', 'lastName')
});
var tom = Person.create({
firstName: 'Tom',
lastName: 'Dale'
});
tom.get('fullName') // 'Tom Dale'
```
You can also define what Ember should do when setting a computed property.
If you try to set a computed property, it will be invoked with the key and
value you want to set it to. You can also accept the previous value as the
third parameter.
```javascript
var Person = Ember.Object.extend({
// these will be supplied by `create`
firstName: null,
lastName: null,
fullName: function(key, value, oldValue) {
// getter
if (arguments.length === 1) {
var firstName = this.get('firstName');
var lastName = this.get('lastName');
return firstName + ' ' + lastName;
// setter
} else {
var name = value.split(' ');
this.set('firstName', name[0]);
this.set('lastName', name[1]);
return value;
}
}.property('firstName', 'lastName')
});
var person = Person.create();
person.set('fullName', 'Peter Wagenet');
person.get('firstName'); // 'Peter'
person.get('lastName'); // 'Wagenet'
```

The purpose of the Ember Instrumentation module is
to provide efficient, general-purpose instrumentation
for Ember.
Subscribe to a listener by using `Ember.subscribe`:
```javascript
Ember.subscribe("render", {
before: function(name, timestamp, payload) {
},
after: function(name, timestamp, payload) {
}
});
```
If you return a value from the `before` callback, that same
value will be passed as a fourth parameter to the `after`
callback.
Instrument a block of code by using `Ember.instrument`:
```javascript
Ember.instrument("render.handlebars", payload, function() {
// rendering logic
}, binding);
```
Event names passed to `Ember.instrument` are namespaced
by periods, from more general to more specific. Subscribers
can listen for events by whatever level of granularity they
are interested in.
In the above example, the event is `render.handlebars`,
and the subscriber listened for all events beginning with
`render`. It would receive callbacks for events named
`render`, `render.handlebars`, `render.container`, or
even `render.handlebars.layout`.

JavaScript (before ES6) does not have a Map implementation. Objects,

Because Ember has a way to get a unique identifier for every object
via `Ember.guidFor`, we can implement a performant Map with arbitrary
keys. Because it is commonly used in low-level bookkeeping, Map is
implemented as a pure JavaScript object for performance.
This implementation follows the current iteration of the ES6 proposal for
maps (http://wiki.ecmascript.org/doku.php?id=harmony:simple_maps_and_sets),
with two exceptions. First, because we need our implementation to be pleasant
on older browsers, we do not use the `delete` name (using `remove` instead).
Second, as we do not have the luxury of in-VM iteration, we implement a
forEach method for iteration.
Map is mocked out to look like an Ember object, so you can do
`Ember.Map.create()` for symmetry with other Ember classes.

Note that Mixins are created with `Ember.Mixin.create`, not

Note that mixins extend a constructor's prototype so arrays and object literals
defined as properties will be shared amongst objects that implement the mixin.
If you want to define a property in a mixin that is not shared, you can define
it either as a computed property or have it be created on initialization of the object.
```javascript
//filters array will be shared amongst any object implementing mixin

//filters will be a separate array for every object implementing the mixin
App.Filterable = Ember.Mixin.create({

//filters will be created as a separate array during the object's initialization
App.Filterable = Ember.Mixin.create({

NOTE: This is a low-level method used by other parts of the API. You almost
never want to call this method directly. Instead you should use
`Ember.mixin()` to define new properties.
Defines a property on an object. This method works much like the ES5
`Object.defineProperty()` method except that it can also accept computed
properties and other special descriptors.
Normally this method takes only three parameters. However if you pass an
instance of `Ember.Descriptor` as the third param then you can pass an
optional value as the fourth parameter. This is often more efficient than
creating new descriptor hashes for each property.
## Examples
```javascript
// ES5 compatible mode
Ember.defineProperty(contact, 'firstName', {
writable: true,
configurable: false,
enumerable: true,
value: 'Charles'
});
// define a simple property
Ember.defineProperty(contact, 'lastName', undefined, 'Jolley');
// define a computed property
Ember.defineProperty(contact, 'fullName', Ember.computed(function() {
return this.firstName+' '+this.lastName;
}).property('firstName', 'lastName'));
```

@for Ember
@param {Object} obj the object to define this property on. This may be a prototype.
@param {String} keyName the name of the property
@param {Ember.Descriptor} [desc] an instance of `Ember.Descriptor` (typically a
computed property) or an ES5 descriptor.
You must provide this or `data` but not both.
@param {*} [data] something other than a descriptor, that will
become the explicit value of this property.

Provides a useful utility for when integrating with non-Ember libraries

Ember utilizes a run-loop to batch and coalesce changes. This works by
marking the start and end of Ember-related Javascript execution.
When using events such as a View's click handler, Ember wraps the event
handler in a run-loop, but when integrating with non-Ember libraries this
can be tedious.
For example, the following is rather verbose but is the correct way to combine
third-party events and Ember code.
```javascript
var that = this;
jQuery(window).on('resize', function(){
run(function(){
that.handleResize();
});

To reduce the boilerplate, the following can be used to construct a

```javascript

}
scheduleIt();
scheduleIt();

Schedules an item to run from within a separate run loop, after

`run.later` with a wait time of 1ms.
```javascript
run.next(myContext, function() {
// code to be executed in the next run loop,
// which will be scheduled after the current one
});
```
Multiple operations scheduled with `run.next` will coalesce
into the same later run loop, along with any other operations
scheduled by `run.later` that expire right around the same
time that `run.next` operations will fire.
Note that there are often alternatives to using `run.next`.
For instance, if you'd like to schedule an operation to happen
after all DOM element operations have completed within the current
run loop, you can make use of the `afterRender` run loop queue (added
by the `ember-views` package, along with the preceding `render` queue
where all the DOM element operations happen). Example:
```javascript
App.MyCollectionView = Ember.CollectionView.extend({
didInsertElement: function() {
run.scheduleOnce('afterRender', this, 'processChildElements');
},
processChildElements: function() {
// ... do something with collectionView's child view
// elements after they've finished rendering, which
// can't be done within the CollectionView's
// `didInsertElement` hook because that gets run
// before the child elements have been added to the DOM.
}
});
```
One benefit of the above approach compared to using `run.next` is
that you will be able to perform DOM/CSS operations before unprocessed
elements are rendered to the screen, which may prevent flickering or
other artifacts caused by delaying processing until after rendering.
The other major benefit to the above approach is that `run.next`
introduces an element of non-determinism, which can make things much
harder to test, due to its reliance on `setTimeout`; it's much harder
to guarantee the order of scheduled operations when they are scheduled
outside of the current run loop, i.e. with `run.next`.

@deprecated
@private
In order to store defaults for a class, a prototype may need to create
a default meta object, which will be inherited by any objects instantiated
from the class's constructor.
However, the properties of that meta object are only shallow-cloned,
so if a property is a hash (like the event system's `listeners` hash),
it will by default be shared across all instances of that class.
This method allows extensions to deeply clone a series of nested hashes or
other complex objects. For instance, the event system might pass
`['listeners', 'foo:change', 'ember157']` to `prepareMetaPath`, which will
walk down the keys provided.
For each key, if the key does not exist, it is created. If it already
exists and it was inherited from its constructor, the constructor's
key is cloned.
You can also pass false for `writable`, which will simply return
undefined if `prepareMetaPath` discovers any part of the path that
shared or undefined.

/**
The `{{action}}` helper registers an HTML element within a template for DOM
event handling and forwards that interaction to the templates's controller
or supplied `target` option (see 'Specifying a Target').
If the controller does not implement the event, the event is sent
to the current route, and it bubbles up the route hierarchy from there.
User interaction with that element will invoke the supplied action name on
the appropriate target. Specifying a non-quoted action name will result in
a bound property lookup at the time the event will be triggered.
Given the following application Handlebars template on the page
```handlebars
<div {{action 'anActionName'}}>
click me
</div>
```
And application code
```javascript
App.ApplicationController = Ember.Controller.extend({
actions: {
anActionName: function() {
}
}
});
```
Will result in the following rendered HTML
```html
<div class="ember-view">
<div data-ember-action="1">
click me
</div>
</div>
```
Clicking "click me" will trigger the `anActionName` action of the
`App.ApplicationController`. In this case, no additional parameters will be passed.
If you provide additional parameters to the helper:
```handlebars
<button {{action 'edit' post}}>Edit</button>
```
Those parameters will be passed along as arguments to the JavaScript
function implementing the action.
### Event Propagation
Events triggered through the action helper will automatically have
`.preventDefault()` called on them. You do not need to do so in your event
handlers. If you need to allow event propagation (to handle file inputs for
example) you can supply the `preventDefault=false` option to the `{{action}}` helper:
```handlebars
<div {{action "sayHello" preventDefault=false}}>
<input type="file" />
<input type="checkbox" />
</div>
```
To disable bubbling, pass `bubbles=false` to the helper:
```handlebars
<button {{action 'edit' post bubbles=false}}>Edit</button>
```
If you need the default handler to trigger you should either register your
own event handler, or use event methods on your view class. See [Ember.View](/api/classes/Ember.View.html)
'Responding to Browser Events' for more information.
### Specifying DOM event type
By default the `{{action}}` helper registers for DOM `click` events. You can
supply an `on` option to the helper to specify a different DOM event name:
```handlebars
<div {{action "anActionName" on="doubleClick"}}>
click me
</div>
```
See `Ember.View` 'Responding to Browser Events' for a list of
acceptable DOM event names.
NOTE: Because `{{action}}` depends on Ember's event dispatch system it will
only function if an `Ember.EventDispatcher` instance is available. An
`Ember.EventDispatcher` instance will be created when a new `Ember.Application`
is created. Having an instance of `Ember.Application` will satisfy this
requirement.
### Specifying whitelisted modifier keys
By default the `{{action}}` helper will ignore click event with pressed modifier
keys. You can supply an `allowedKeys` option to specify which keys should not be ignored.
```handlebars
<div {{action "anActionName" allowedKeys="alt"}}>
click me
</div>
```
This way the `{{action}}` will fire when clicking with the alt key pressed down.
Alternatively, supply "any" to the `allowedKeys` option to accept any combination of modifier keys.
```handlebars
<div {{action "anActionName" allowedKeys="any"}}>
click me with any key pressed
</div>
```
### Specifying a Target
There are several possible target objects for `{{action}}` helpers:
In a typical Ember application, where views are managed through use of the
`{{outlet}}` helper, actions will bubble to the current controller, then
to the current route, and then up the route hierarchy.
Alternatively, a `target` option can be provided to the helper to change
which object will receive the method call. This option must be a path
to an object, accessible in the current context:
```handlebars
{{! the application template }}
<div {{action "anActionName" target=view}}>
click me
</div>
```
```javascript
App.ApplicationView = Ember.View.extend({
actions: {
anActionName: function(){}
}
});
```
### Additional Parameters
You may specify additional parameters to the `{{action}}` helper. These
parameters are passed along as the arguments to the JavaScript function
implementing the action.
```handlebars
{{#each person in people}}
<div {{action "edit" person}}>
click me
</div>
{{/each}}
```
Clicking "click me" will trigger the `edit` method on the current controller
with the value of `person` as a parameter.

The `{{link-to}}` helper renders a link to the supplied
`routeName` passing an optionally supplied model to the
route as its `model` context of the route. The block
for `{{link-to}}` becomes the innerHTML of the rendered
element:
```handlebars
{{#link-to 'photoGallery'}}
Great Hamster Photos
{{/link-to}}
```
```html
<a href="/hamster-photos">
Great Hamster Photos
</a>
```
### Supplying a tagName
By default `{{link-to}}` renders an `<a>` element. This can
be overridden for a single use of `{{link-to}}` by supplying
a `tagName` option:
```handlebars
{{#link-to 'photoGallery' tagName="li"}}
Great Hamster Photos
{{/link-to}}
```
```html
<li>
Great Hamster Photos
</li>
```
To override this option for your entire application, see
"Overriding Application-wide Defaults".
### Disabling the `link-to` helper
By default `{{link-to}}` is enabled.
any passed value to `disabled` helper property will disable the `link-to` helper.
static use: the `disabled` option:
```handlebars
{{#link-to 'photoGallery' disabled=true}}
Great Hamster Photos
{{/link-to}}
```
dynamic use: the `disabledWhen` option:
```handlebars
{{#link-to 'photoGallery' disabledWhen=controller.someProperty}}
Great Hamster Photos
{{/link-to}}
```
any passed value to `disabled` will disable it except `undefined`.
to ensure that only `true` disable the `link-to` helper you can
override the global behaviour of `Ember.LinkView`.
```javascript
Ember.LinkView.reopen({
disabled: Ember.computed(function(key, value) {
if (value !== undefined) {
this.set('_isDisabled', value === true);
}
return value === true ? get(this, 'disabledClass') : false;
})
});
```
see "Overriding Application-wide Defaults" for more.
### Handling `href`
`{{link-to}}` will use your application's Router to
fill the element's `href` property with a url that
matches the path to the supplied `routeName` for your
routers's configured `Location` scheme, which defaults
to Ember.HashLocation.
### Handling current route
`{{link-to}}` will apply a CSS class name of 'active'
when the application's current route matches
the supplied routeName. For example, if the application's
current route is 'photoGallery.recent' the following
use of `{{link-to}}`:
```handlebars
{{#link-to 'photoGallery.recent'}}
Great Hamster Photos from the last week
{{/link-to}}
```
will result in
```html
<a href="/hamster-photos/this-week" class="active">
Great Hamster Photos
</a>
```
The CSS class name used for active classes can be customized
for a single use of `{{link-to}}` by passing an `activeClass`
option:
```handlebars
{{#link-to 'photoGallery.recent' activeClass="current-url"}}
Great Hamster Photos from the last week
{{/link-to}}
```
```html
<a href="/hamster-photos/this-week" class="current-url">
Great Hamster Photos
</a>
```
To override this option for your entire application, see
"Overriding Application-wide Defaults".
### Supplying a model
An optional model argument can be used for routes whose
paths contain dynamic segments. This argument will become
the model context of the linked route:
```javascript
App.Router.map(function() {
this.resource("photoGallery", {path: "hamster-photos/:photo_id"});
});
```
```handlebars
{{#link-to 'photoGallery' aPhoto}}
{{aPhoto.title}}
{{/link-to}}
```
```html
<a href="/hamster-photos/42">
Tomster
</a>
```
### Supplying multiple models
For deep-linking to route paths that contain multiple
dynamic segments, multiple model arguments can be used.
As the router transitions through the route path, each
supplied model argument will become the context for the
route with the dynamic segments:
```javascript
App.Router.map(function() {
this.resource("photoGallery", {path: "hamster-photos/:photo_id"}, function() {
this.route("comment", {path: "comments/:comment_id"});
});
});
```
This argument will become the model context of the linked route:
```handlebars
{{#link-to 'photoGallery.comment' aPhoto comment}}
{{comment.body}}
{{/link-to}}
```
```html
<a href="/hamster-photos/42/comment/718">
A+++ would snuggle again.
</a>
```
### Supplying an explicit dynamic segment value
If you don't have a model object available to pass to `{{link-to}}`,
an optional string or integer argument can be passed for routes whose
paths contain dynamic segments. This argument will become the value
of the dynamic segment:
```javascript
App.Router.map(function() {
this.resource("photoGallery", {path: "hamster-photos/:photo_id"});
});
```
```handlebars
{{#link-to 'photoGallery' aPhotoId}}
{{aPhoto.title}}
{{/link-to}}
```
```html
<a href="/hamster-photos/42">
Tomster
</a>
```
When transitioning into the linked route, the `model` hook will
be triggered with parameters including this passed identifier.
### Allowing Default Action
By default the `{{link-to}}` helper prevents the default browser action
by calling `preventDefault()` as this sort of action bubbling is normally
handled internally and we do not want to take the browser to a new URL (for
example).
If you need to override this behavior specify `preventDefault=false` in
your template:
```handlebars
{{#link-to 'photoGallery' aPhotoId preventDefault=false}}
{{aPhotoId.title}}
{{/link-to}}
```
### Overriding attributes
You can override any given property of the Ember.LinkView
that is generated by the `{{link-to}}` helper by passing
key/value pairs, like so:
```handlebars
{{#link-to aPhoto tagName='li' title='Following this link will change your life' classNames='pic sweet'}}
Uh-mazing!
{{/link-to}}
```
See [Ember.LinkView](/api/classes/Ember.LinkView.html) for a
complete list of overrideable properties. Be sure to also
check out inherited properties of `LinkView`.
### Overriding Application-wide Defaults
``{{link-to}}`` creates an instance of Ember.LinkView
for rendering. To override options for your entire
application, reopen Ember.LinkView and supply the
desired values:
``` javascript
Ember.LinkView.reopen({
activeClass: "is-active",
tagName: 'li'
})
```
It is also possible to override the default event in
this manner:
``` javascript
Ember.LinkView.reopen({
eventName: 'customEventName'
});
```

@param {String} routeName

/**
The `outlet` helper is a placeholder that the router will fill in with
the appropriate template based on the current state of the application.
``` handlebars
{{outlet}}
```
By default, a template based on Ember's naming conventions will be rendered
into the `outlet` (e.g. `App.PostsRoute` will render the `posts` template).
You can render a different template by using the `render()` method in the
route's `renderTemplate` hook. The following will render the `favoritePost`
template into the `outlet`.
``` javascript
App.PostsRoute = Ember.Route.extend({
renderTemplate: function() {
this.render('favoritePost');
}
});
```
You can create custom named outlets for more control.
``` handlebars
{{outlet 'favoritePost'}}
{{outlet 'posts'}}
```
Then you can define what template is rendered into each outlet in your
route.
``` javascript
App.PostsRoute = Ember.Route.extend({
renderTemplate: function() {
this.render('favoritePost', { outlet: 'favoritePost' });
this.render('posts', { outlet: 'posts' });
}
});
```
You can specify the view that the outlet uses to contain and manage the
templates rendered into it.
``` handlebars
{{outlet view='sectionContainer'}}
```
``` javascript
App.SectionContainer = Ember.ContainerView.extend({
tagName: 'section',
classNames: ['special']
});

Calling ``{{render}}`` from within a template will insert another
template that matches the provided name. The inserted template will
access its properties on its own controller (rather than the controller
of the parent template).
If a view class with the same name exists, the view class also will be used.
Note: A given controller may only be used *once* in your app in this manner.
A singleton instance of the controller will be created for you.
Example:
```javascript
App.NavigationController = Ember.Controller.extend({
who: "world"
});
```
```handlebars
<!-- navigation.hbs -->
Hello, {{who}}.
```
```handelbars
<!-- application.hbs -->
<h1>My great app</h1>
{{render "navigation"}}
```
```html
<h1>My great app</h1>
<div class='ember-view'>
Hello, world.
</div>
```
Optionally you may provide a second argument: a property path
that will be bound to the `model` property of the controller.
If a `model` property path is specified, then a new instance of the
controller will be created and `{{render}}` can be used multiple times
with the same name.
For example if you had this `author` template.
```handlebars
<div class="author">
Written by {{firstName}} {{lastName}}.
Total Posts: {{postCount}}
</div>
```
You could render it inside the `post` template using the `render` helper.
```handlebars
<div class="post">
<h1>{{title}}</h1>
<div>{{body}}</div>
{{render "author" author}}
</div>

/**
Ember.Location returns an instance of the correct implementation of
the `location` API.
## Implementations
You can pass an implementation name (`hash`, `history`, `none`) to force a
particular implementation to be used in your application.
### HashLocation
Using `HashLocation` results in URLs with a `#` (hash sign) separating the
server side URL portion of the URL from the portion that is used by Ember.
This relies upon the `hashchange` event existing in the browser.
Example:
```javascript
App.Router.map(function() {
this.resource('posts', function() {
this.route('new');
});
});
App.Router.reopen({
location: 'hash'
});
```
This will result in a posts.new url of `/#/posts/new`.
### HistoryLocation
Using `HistoryLocation` results in URLs that are indistinguishable from a
standard URL. This relies upon the browser's `history` API.
Example:
```javascript
App.Router.map(function() {
this.resource('posts', function() {
this.route('new');
});
});
App.Router.reopen({
location: 'history'
});
```
This will result in a posts.new url of `/posts/new`.
Keep in mind that your server must serve the Ember app at all the routes you
define.
### AutoLocation
Using `AutoLocation`, the router will use the best Location class supported by
the browser it is running in.
Browsers that support the `history` API will use `HistoryLocation`, those that
do not, but still support the `hashchange` event will use `HashLocation`, and
in the rare case neither is supported will use `NoneLocation`.
Example:
```javascript
App.Router.map(function() {
this.resource('posts', function() {
this.route('new');
});
});
App.Router.reopen({
location: 'auto'
});
```
This will result in a posts.new url of `/posts/new` for modern browsers that
support the `history` api or `/#/posts/new` for older ones, like Internet
Explorer 9 and below.
When a user visits a link to your application, they will be automatically
upgraded or downgraded to the appropriate `Location` class, with the URL
transformed accordingly, if needed.
Keep in mind that since some of your users will use `HistoryLocation`, your
server must serve the Ember app at all the routes you define.
### NoneLocation
Using `NoneLocation` causes Ember to not store the applications URL state
in the actual URL. This is generally used for testing purposes, and is one
of the changes made when calling `App.setupForTesting()`.
## Location API
Each location implementation must provide the following methods:
* implementation: returns the string name used to reference the implementation.
* getURL: returns the current URL.
* setURL(path): sets the current URL.
* replaceURL(path): replace the current URL (optional).
* onUpdateURL(callback): triggers the callback when the URL changes.
* formatURL(url): formats `url` to be placed into `href` attribute.
Calling setURL or replaceURL will not trigger onUpdateURL callbacks.

This is useful in many ways, as the controller specified will be:

You can also redirect elsewhere by calling
`this.transitionTo('elsewhere')` from within `willTransition`.
Note that `willTransition` will not be fired for the
redirecting `transitionTo`, since `willTransition` doesn't
fire when there is already a transition underway. If you want
subsequent `willTransition` actions to fire for the redirecting
transition, you must first explicitly call
`transition.abort()`.

When attempting to transition into a route, any of the hooks
may return a promise that rejects, at which point an `error`
action will be fired on the partially-entered routes, allowing
for per-route error handling logic, or shared error handling
logic defined on a parent route.
Here is an example of an error handler that will be invoked
for rejected promises from the various hooks on the route,
as well as any unhandled errors from child routes:
```js
App.AdminRoute = Ember.Route.extend({
beforeModel: function() {
return Ember.RSVP.reject("bad things!");
},
actions: {
error: function(error, transition) {
// Assuming we got here due to the error in `beforeModel`,
// we can expect that error === "bad things!",
// but a promise model rejecting would also
// call this hook, as would any errors encountered
// in `afterModel`.
// The `error` hook is also provided the failed
// `transition`, which can be stored and later
// `.retry()`d if desired.
this.transitionTo('login');
}
}
});
```
`error` actions that bubble up all the way to `ApplicationRoute`
will fire a default error handler that logs the error. You can
specify your own global default error handler by overriding the
`error` handler on `ApplicationRoute`:
```js
App.ApplicationRoute = Ember.Route.extend({
actions: {
error: function(error, transition) {
this.controllerFor('banner').displayError(error.message);
}
}
});
```

Transition the application into another route. The route may
be either a single route or route path:
```javascript

Optionally supply a model for the route in question. The model
will be serialized into the URL using the `serialize` hook of
the route:
```javascript
this.transitionTo('blogPost', aPost);
```
If a literal is passed (such as a number or a string), it will
be treated as an identifier instead. In this case, the `model`
hook of the route will be triggered:
```javascript
this.transitionTo('blogPost', 1);
```
Multiple models will be applied last to first recursively up the
resource tree.
```javascript
App.Router.map(function() {
this.resource('blogPost', {path:':blogPostId'}, function(){
this.resource('blogComment', {path: ':blogCommentId'});
});
});
this.transitionTo('blogComment', aPost, aComment);
this.transitionTo('blogComment', 1, 13);
```
It is also possible to pass a URL (a string that starts with a
`/`). This is intended for testing and debugging purposes and
should rarely be used in production code.
```javascript
this.transitionTo('/');
this.transitionTo('/blog/post/1/comment/13');
```
See also 'replaceWith'.
Simple Transition Example
```javascript
App.Router.map(function() {
this.route("index");
this.route("secret");
this.route("fourOhFour", { path: "*:"});
});
App.IndexRoute = Ember.Route.extend({
actions: {
moveToSecret: function(context){
if (authorized()){
this.transitionTo('secret', context);
}
this.transitionTo('fourOhFour');
}
}
});
```
Transition to a nested route
```javascript
App.Router.map(function() {

App.IndexRoute = Ember.Route.extend({

/**
This hook is the first of the route entry validation hooks
called when an attempt is made to transition into a route
or one of its children. It is called before `model` and
`afterModel`, and is appropriate for cases when:
1) A decision can be made to redirect elsewhere without
needing to resolve the model first.
2) Any async operations need to occur first before the
model is attempted to be resolved.
This hook is provided the current `transition` attempt
as a parameter, which can be used to `.abort()` the transition,
save it for a later `.retry()`, or retrieve values set
on it from a previous hook. You can also just call
`this.transitionTo` to another route to implicitly
abort the `transition`.
You can return a promise from this hook to pause the
transition until the promise resolves (or rejects). This could
be useful, for instance, for retrieving async code from
the server that is required to enter a route.
```js
App.PostRoute = Ember.Route.extend({
beforeModel: function(transition) {
if (!App.Post) {
return Ember.$.getScript('/models/post.js');
}
}
});
```
If `App.Post` doesn't exist in the above example,
`beforeModel` will use jQuery's `getScript`, which
returns a promise that resolves after the server has
successfully retrieved and executed the code from the
server. Note that if an error were to occur, it would
be passed to the `error` hook on `Ember.Route`, but
it's also possible to handle errors specific to
`beforeModel` right from within the hook (to distinguish
from the shared error handling behavior of the `error`
hook):
```js
App.PostRoute = Ember.Route.extend({
beforeModel: function(transition) {
if (!App.Post) {
var self = this;
return Ember.$.getScript('post.js').then(null, function(e) {
self.transitionTo('help');
// Note that the above transitionTo will implicitly
// halt the transition. If you were to return
// nothing from this promise reject handler,
// according to promise semantics, that would
// convert the reject into a resolve and the
// transition would continue. To propagate the
// error so that it'd be handled by the `error`
// hook, you would have to either
return Ember.RSVP.reject(e);
});
}
}
});
```

`redirect` and `afterModel` behave very similarly and are

distinction in the case that, from one of these hooks, a
redirect into a child route of this route occurs: redirects
from `afterModel` essentially invalidate the current attempt
to enter this route, and will result in this route's `beforeModel`,
`model`, and `afterModel` hooks being fired again within
the new, redirecting transition. Redirects that occur within
the `redirect` hook, on the other hand, will _not_ cause
these hooks to be fired again the second time around; in
other words, by the time the `redirect` hook has been called,

A hook you can implement to convert the URL into the model for
this route.
```js
App.Router.map(function() {
this.resource('post', {path: '/posts/:post_id'});
});
```
The model for the `post` route is `App.Post.find(params.post_id)`.
By default, if your route has a dynamic segment ending in `_id`:
* The model class is determined from the segment (`post_id`'s
class is `App.Post`)
* The find method is called on the model class with the value of
the dynamic segment.
Note that for routes with dynamic segments, this hook is only
executed when entered via the URL. If the route is entered
through a transition (e.g. when using the `link-to` Handlebars
helper), then a model context is already provided and this hook
is not called. Routes without dynamic segments will always
execute the model hook.
This hook follows the asynchronous/promise semantics
described in the documentation for `beforeModel`. In particular,
if a promise returned from `model` fails, the error will be
handled by the `error` hook on `Ember.Route`.
Example
```js
App.PostRoute = Ember.Route.extend({
model: function(params) {
return App.Post.find(params.post_id);
}
});

/**
A hook you can use to setup the controller for the current route.
This method is called with the controller for the current route and the
model supplied by the `model` hook.
By default, the `setupController` hook sets the `model` property of
the controller to the `model`.
If you implement the `setupController` hook in your Route, it will
prevent this default behavior. If you want to preserve that behavior
when implementing your `setupController` function, make sure to call
`_super`:
```js
App.PhotosRoute = Ember.Route.extend({
model: function() {
return App.Photo.find();
},
setupController: function (controller, model) {
// Call _super for default behavior
this._super(controller, model);
// Implement your custom setup after
this.controllerFor('application').set('showingPhotos', true);
}
});
```
This means that your template will get a proxy for the model as its
context, and you can act as though the model itself was the context.
The provided controller will be one resolved based on the name
of this route.
If no explicit controller is defined, Ember will automatically create
an appropriate controller for the model.
* if the model is an `Ember.Array` (including record arrays from Ember
Data), the controller is an `Ember.ArrayController`.
* otherwise, the controller is an `Ember.ObjectController`.
As an example, consider the router:
```js
App.Router.map(function() {
this.resource('post', {path: '/posts/:post_id'});
});
```
For the `post` route, a controller named `App.PostController` would
be used if it is defined. If it is not defined, an `Ember.ObjectController`
instance would be used.
Example
```js
App.PostRoute = Ember.Route.extend({
setupController: function(controller, model) {
controller.set('model', model);
}

`render` is used to render a template into a region of another template

For example, given the following minimal router and templates:
```js
Router.map(function() {
this.resource('photos');
});
```
```handlebars
<!-- application.hbs -->
<div class='something-in-the-app-hbs'>
{{outlet "anOutletName"}}
</div>
```
```handlebars
<!-- photos.hbs -->
<h1>Photos</h1>
```
You can render `photos.hbs` into the `"anOutletName"` outlet of
`application.hbs` by calling `render`:
```js
// posts route
Ember.Route.extend({
renderTemplate: function(){
this.render('posts', {
into: 'application',
outlet: 'anOutletName'
})
}
});
```
`render` additionally allows you to supply which `view`, `controller`, and
`model` objects should be loaded and associated with the rendered template.
```js
// posts route
Ember.Route.extend({
renderTemplate: function(controller, model){
this.render('posts', { // the template to render, referenced by name
into: 'application', // the template to render into, referenced by name
outlet: 'anOutletName', // the outlet inside `options.template` to render into.
view: 'aViewName', // the view to use for this template, referenced by name
controller: 'someControllerName', // the controller to use for this template, referenced by name
model: model // the model to set on `options.controller`.
})
}
});
```
The string values provided for the template name, view, and controller
will eventually pass through to the resolver for lookup. See
Ember.Resolver for how these are mapped to JavaScript objects in your
application.
Not all options need to be passed to `render`. Default values will be used
based on the name of the route specified in the router or the Route's
`controllerName`, `viewName` and and `templateName` properties.
For example:
```js
// router

```js
// post route
PostRoute = App.Route.extend({
renderTemplate: function() {
this.render(); // all defaults apply

```
The name of the `PostRoute`, defined by the router, is `post`.
The following equivalent default options will be applied when
the Route calls `render`:
```js
//
this.render('post', { // the template name associated with 'post' Route
into: 'application', // the parent route to 'post' Route
outlet: 'main', // {{outlet}} and {{outlet 'main' are synonymous}},
view: 'post', // the view associated with the 'post' Route
controller: 'post', // the controller associated with the 'post' Route
})
```
By default the controller's `model` will be the route's model, so it does not
need to be passed unless you wish to change which model is being used.
@method render
@param {String} name the name of the template to render
@param {Object} options the options
@param {String} options.into the template to render into,
referenced by name. Defaults to the parent template
@param {String} options.outlet the outlet inside `options.template` to render into.
Defaults to 'main'
@param {String} options.controller the controller to use for this template,
referenced by name. Defaults to the Route's paired controller
@param {String} options.model the model object to set on `options.controller`
Defaults to the return value of the Route's model hook

/**
Creates a computed property which operates on dependent arrays and
is updated with "one at a time" semantics. When items are added or
removed from the dependent array(s) an array computed only operates
on the change instead of re-evaluating the entire array. This should
return an array, if you'd like to use "one at a time" semantics and
compute some value other then an array look at
`Ember.reduceComputed`.
If there are more than one arguments the first arguments are
considered to be dependent property keys. The last argument is
required to be an options object. The options object can have the
following three properties.
`initialize` - An optional initialize function. Typically this will be used
to set up state on the instanceMeta object.
`removedItem` - A function that is called each time an element is
removed from the array.
`addedItem` - A function that is called each time an element is
added to the array.
The `initialize` function has the following signature:
```javascript
function(array, changeMeta, instanceMeta)
```
`array` - The initial value of the arrayComputed, an empty array.
`changeMeta` - An object which contains meta information about the
computed. It contains the following properties:
- `property` the computed property
- `propertyName` the name of the property on the object
`instanceMeta` - An object that can be used to store meta
information needed for calculating your computed. For example a
unique computed might use this to store the number of times a given
element is found in the dependent array.
The `removedItem` and `addedItem` functions both have the following signature:
```javascript
function(accumulatedValue, item, changeMeta, instanceMeta)
```
`accumulatedValue` - The value returned from the last time
`removedItem` or `addedItem` was called or an empty array.
`item` - the element added or removed from the array
`changeMeta` - An object which contains meta information about the
change. It contains the following properties:
- `property` the computed property
- `propertyName` the name of the property on the object
- `index` the index of the added or removed item
- `item` the added or removed item: this is exactly the same as
the second arg
- `arrayChanged` the array that triggered the change. Can be
useful when depending on multiple arrays.
For property changes triggered on an item property change (when
depKey is something like `someArray.@each.someProperty`),
`changeMeta` will also contain the following property:
- `previousValues` an object whose keys are the properties that changed on
the item, and whose values are the item's previous values.
`previousValues` is important Ember coalesces item property changes via
Ember.run.once. This means that by the time removedItem gets called, item has
the new values, but you may need the previous value (eg for sorting &
filtering).
`instanceMeta` - An object that can be used to store meta
information needed for calculating your computed. For example a
unique computed might use this to store the number of times a given
element is found in the dependent array.
The `removedItem` and `addedItem` functions should return the accumulated
value. It is acceptable to not return anything (ie return undefined)
to invalidate the computation. This is generally not a good idea for
arrayComputed but it's used in eg max and min.
Example
```javascript
Ember.computed.map = function(dependentKey, callback) {
var options = {
addedItem: function(array, item, changeMeta, instanceMeta) {
var mapped = callback(item);
array.insertAt(changeMeta.index, mapped);
return array;
},
removedItem: function(array, item, changeMeta, instanceMeta) {
array.removeAt(changeMeta.index, 1);
return array;
}
};
return Ember.arrayComputed(dependentKey, options);
};
```

/**
Creates a computed property which operates on dependent arrays and
is updated with "one at a time" semantics. When items are added or
removed from the dependent array(s) a reduce computed only operates
on the change instead of re-evaluating the entire array.
If there are more than one arguments the first arguments are
considered to be dependent property keys. The last argument is
required to be an options object. The options object can have the
following four properties:
`initialValue` - A value or function that will be used as the initial
value for the computed. If this property is a function the result of calling
the function will be used as the initial value. This property is required.
`initialize` - An optional initialize function. Typically this will be used
to set up state on the instanceMeta object.
`removedItem` - A function that is called each time an element is removed
from the array.
`addedItem` - A function that is called each time an element is added to
the array.
The `initialize` function has the following signature:
```javascript
function(initialValue, changeMeta, instanceMeta)
```
`initialValue` - The value of the `initialValue` property from the
options object.
`changeMeta` - An object which contains meta information about the
computed. It contains the following properties:
- `property` the computed property
- `propertyName` the name of the property on the object
`instanceMeta` - An object that can be used to store meta
information needed for calculating your computed. For example a
unique computed might use this to store the number of times a given
element is found in the dependent array.
The `removedItem` and `addedItem` functions both have the following signature:
```javascript
function(accumulatedValue, item, changeMeta, instanceMeta)
```
`accumulatedValue` - The value returned from the last time
`removedItem` or `addedItem` was called or `initialValue`.
`item` - the element added or removed from the array
`changeMeta` - An object which contains meta information about the
change. It contains the following properties:
- `property` the computed property
- `propertyName` the name of the property on the object
- `index` the index of the added or removed item
- `item` the added or removed item: this is exactly the same as
the second arg
- `arrayChanged` the array that triggered the change. Can be
useful when depending on multiple arrays.
For property changes triggered on an item property change (when
depKey is something like `someArray.@each.someProperty`),
`changeMeta` will also contain the following property:
- `previousValues` an object whose keys are the properties that changed on
the item, and whose values are the item's previous values.
`previousValues` is important Ember coalesces item property changes via
Ember.run.once. This means that by the time removedItem gets called, item has
the new values, but you may need the previous value (eg for sorting &
filtering).
`instanceMeta` - An object that can be used to store meta
information needed for calculating your computed. For example a
unique computed might use this to store the number of times a given
element is found in the dependent array.
The `removedItem` and `addedItem` functions should return the accumulated
value. It is acceptable to not return anything (ie return undefined)
to invalidate the computation. This is generally not a good idea for
arrayComputed but it's used in eg max and min.
Note that observers will be fired if either of these functions return a value
that differs from the accumulated value. When returning an object that
mutates in response to array changes, for example an array that maps
everything from some other array (see `Ember.computed.map`), it is usually
important that the *same* array be returned to avoid accidentally triggering observers.
Example
```javascript
Ember.computed.max = function(dependentKey) {
return Ember.reduceComputed(dependentKey, {
initialValue: -Infinity,
addedItem: function(accumulatedValue, item, changeMeta, instanceMeta) {
return Math.max(accumulatedValue, item);
},
removedItem: function(accumulatedValue, item, changeMeta, instanceMeta) {
if (item < accumulatedValue) {
return accumulatedValue;
}
}
});
};
```
Dependent keys may refer to `@this` to observe changes to the object itself,
which must be array-like, rather than a property of the object. This is
mostly useful for array proxies, to ensure objects are retrieved via
`objectAtContent`. This is how you could sort items by properties defined on an item controller.
Example
```javascript
App.PeopleController = Ember.ArrayController.extend({
itemController: 'person',
sortedPeople: Ember.computed.sort('@this.@each.reversedName', function(personA, personB) {
// `reversedName` isn't defined on Person, but we have access to it via
// the item controller App.PersonController. If we'd used
// `content.@each.reversedName` above, we would be getting the objects
// directly and not have access to `reversedName`.
//
var reversedNameA = get(personA, 'reversedName'),
reversedNameB = get(personB, 'reversedName');
return Ember.compare(reversedNameA, reversedNameB);
})
});
App.PersonController = Ember.ObjectController.extend({
reversedName: function() {
return reverse(get(this, 'name'));
}.property('name')
});
```
Dependent keys whose values are not arrays are treated as regular
dependencies: when they change, the computed property is completely
recalculated. It is sometimes useful to have dependent arrays with similar
semantics. Dependent keys which end in `.[]` do not use "one at a time"
semantics. When an item is added or removed from such a dependency, the
computed property is completely recomputed.
When the computed property is completely recomputed, the `accumulatedValue`
is discarded, it starts with `initialValue` again, and each item is passed
to `addedItem` in turn.
Example
```javascript
Ember.Object.extend({
// When `string` is changed, `computed` is completely recomputed.
string: 'a string',
// When an item is added to `array`, `addedItem` is called.
array: [],
// When an item is added to `anotherArray`, `computed` is completely
// recomputed.
anotherArray: [],
computed: Ember.reduceComputed('string', 'array', 'anotherArray.[]', {
addedItem: addedItemCallback,
removedItem: removedItemCallback
})
});
```

/**
`Ember.ArrayController` provides a way for you to publish a collection of
objects so that you can easily bind to the collection from a Handlebars
`#each` helper, an `Ember.CollectionView`, or other controllers.
The advantage of using an `ArrayController` is that you only have to set up
your view bindings once; to change what's displayed, simply swap out the
`model` property on the controller.
For example, imagine you wanted to display a list of items fetched via an XHR
request. Create an `Ember.ArrayController` and set its `model` property:
```javascript
MyApp.listController = Ember.ArrayController.create();
$.get('people.json', function(data) {
MyApp.listController.set('model', data);
});
```
Then, create a view that binds to your new controller:
```handlebars
{{#each MyApp.listController}}
{{firstName}} {{lastName}}
{{/each}}
```
Although you are binding to the controller, the behavior of this controller
is to pass through any methods or properties to the underlying array. This
capability comes from `Ember.ArrayProxy`, which this class inherits from.
Sometimes you want to display computed properties within the body of an
`#each` helper that depend on the underlying items in `model`, but are not
present on those items. To do this, set `itemController` to the name of a
controller (probably an `ObjectController`) that will wrap each individual item.
For example:
```handlebars
{{#each post in controller}}
<li>{{post.title}} ({{post.titleLength}} characters)</li>
{{/each}}
```
```javascript
App.PostsController = Ember.ArrayController.extend({
itemController: 'post'
});
App.PostController = Ember.ObjectController.extend({
// the `title` property will be proxied to the underlying post.
titleLength: function() {
return this.get('title').length;
}.property('title')
});
```
In some cases it is helpful to return a different `itemController` depending
on the particular item. Subclasses can do this by overriding
`lookupItemController`.
For example:
```javascript
App.MyArrayController = Ember.ArrayController.extend({
lookupItemController: function( object ) {
if (object.get('isSpecial')) {
return "special"; // use App.SpecialController
} else {
return "regular"; // use App.RegularController
}
}
});
```
The itemController instances will have a `parentController` property set to
the `ArrayController` instance.

The `property` extension of Javascript's Function prototype is available
when `Ember.EXTEND_PROTOTYPES` or `Ember.EXTEND_PROTOTYPES.Function` is
`true`, which is the default.
Computed properties allow you to treat a function like a property:
```javascript
MyApp.President = Ember.Object.extend({
firstName: '',
lastName: '',
fullName: function() {
return this.get('firstName') + ' ' + this.get('lastName');
// Call this flag to mark the function as a property
}.property()
});
var president = MyApp.President.create({
firstName: "Barack",
lastName: "Obama"
});
president.get('fullName'); // "Barack Obama"
```
Treating a function like a property is useful because they can work with
bindings, just like any other property.
Many computed properties have dependencies on other properties. For
example, in the above example, the `fullName` property depends on
`firstName` and `lastName` to determine its value. You can tell Ember
about these dependencies like this:
```javascript
MyApp.President = Ember.Object.extend({
firstName: '',
lastName: '',
fullName: function() {
return this.get('firstName') + ' ' + this.get('lastName');
// Tell Ember.js that this computed property depends on firstName
// and lastName
}.property('firstName', 'lastName')
});
```
Make sure you list these dependencies so Ember knows when to update
bindings that connect to a computed property. Changing a dependency
will not immediately trigger an update of the computed property, but
will instead clear the cache so that it is updated when the next `get`
is called on the property.

`Ember.ActionHandler` is available on some familiar classes including
`Ember.Route`, `Ember.View`, `Ember.Component`, and controllers such as
`Ember.Controller` and `Ember.ObjectController`.
(Internally the mixin is used by `Ember.CoreView`, `Ember.ControllerMixin`,
and `Ember.Route` and available to the above classes through
inheritance.)
@class ActionHandler
@namespace Ember
*/
var ActionHandler = Mixin.create({
mergedProperties: ['_actions'],
/**
The collection of functions, keyed by name, available on this
`ActionHandler` as action targets.
These functions will be invoked when a matching `{{action}}` is triggered
from within a template and the application's current route is this route.
Actions can also be invoked from other parts of your application
via `ActionHandler#send`.
The `actions` hash will inherit action handlers from
the `actions` hash defined on extended parent classes
or mixins rather than just replace the entire hash, e.g.:
```js
App.CanDisplayBanner = Ember.Mixin.create({
actions: {
displayBanner: function(msg) {
// ...
}
}
});
App.WelcomeRoute = Ember.Route.extend(App.CanDisplayBanner, {
actions: {
playMusic: function() {
// ...
}
}
});
// `WelcomeRoute`, when active, will be able to respond
// to both actions, since the actions hash is merged rather
// then replaced when extending mixins / parent classes.
this.send('displayBanner');
this.send('playMusic');
```
Within a Controller, Route, View or Component's action handler,
the value of the `this` context is the Controller, Route, View or
Component object:
```js
App.SongRoute = Ember.Route.extend({
actions: {
myAction: function() {
this.controllerFor("song");
this.transitionTo("other.route");
...
}
}
});
```
It is also possible to call `this._super()` from within an
action handler if it overrides a handler defined on a parent
class or mixin:
Take for example the following routes:
```js
App.DebugRoute = Ember.Mixin.create({
actions: {
debugRouteInformation: function() {
console.debug("trololo");
}
}
});
App.AnnoyingDebugRoute = Ember.Route.extend(App.DebugRoute, {
actions: {
debugRouteInformation: function() {
// also call the debugRouteInformation of mixed in App.DebugRoute
this._super();
// show additional annoyance
window.alert(...);
}
}
});
```
## Bubbling
By default, an action will stop bubbling once a handler defined
on the `actions` hash handles it. To continue bubbling the action,
you must return `true` from the handler:
```js
App.Router.map(function() {
this.resource("album", function() {
this.route("song");
});
});
App.AlbumRoute = Ember.Route.extend({
actions: {
startPlaying: function() {
}
}
});
App.AlbumSongRoute = Ember.Route.extend({
actions: {
startPlaying: function() {
// ...
if (actionShouldAlsoBeTriggeredOnParentRoute) {
return true;
}
}
}
});
```

concrete implementation, but it can be used up by other classes that want
to appear like arrays.
For example, ArrayProxy and ArrayController are both concrete classes that can
be instantiated to implement array-like behavior. Both of these classes use
the Array Mixin by way of the MutableArray mixin, which allows observable
changes to be made to the underlying array.
Unlike `Ember.Enumerable,` this mixin defines methods specifically for
collections that provide index-ordered access to their contents. When you
are designing code that needs to accept any kind of Array-like object, you
should use these methods instead of Array primitives because these will
properly notify observers of changes to the array.
Although these methods are efficient, they do add a layer of indirection to
your application so it is a good idea to use them only when you need the
flexibility of using both true JavaScript arrays and "virtual" arrays such
as controllers and collections.
You can use the methods defined in this module to access and modify array
contents in a KVO-friendly way. You can also be notified whenever the
membership of an array changes by using `.observes('myArray.[]')`.
To support `Ember.Array` in your own class, you must override two
primitives to use it: `replace()` and `objectAt()`.
Note that the Ember.Array mixin also incorporates the `Ember.Enumerable`
mixin. All `Ember.Array`-like objects are also enumerable.

/**
This mixin defines the common interface implemented by enumerable objects
in Ember. Most of these methods follow the standard Array iteration
API defined up to JavaScript 1.8 (excluding language-specific features that
cannot be emulated in older versions of JavaScript).
This mixin is applied automatically to the Array class on page load, so you
can use any of these methods on simple arrays. If Array already implements
one of these methods, the mixin will not override them.
## Writing Your Own Enumerable
To make your own custom class enumerable, you need two items:
1. You must have a length property. This property should change whenever
the number of items in your enumerable object changes. If you use this
with an `Ember.Object` subclass, you should be sure to change the length
property using `set().`
2. You must implement `nextObject().` See documentation.
Once you have these two methods implemented, apply the `Ember.Enumerable` mixin
to your class and you will be able to enumerate the contents of your object
like any other collection.
## Using Ember Enumeration with Other Libraries
Many other libraries provide some kind of iterator or enumeration like
facility. This is often where the most common API conflicts occur.
Ember's API is designed to be as friendly as possible with other
libraries by implementing only methods that mostly correspond to the
JavaScript 1.8 API.
@class Enumerable

@since Ember 0.9
*/
__exports__["default"] = Mixin.create({
/**
Implement this method to make your class enumerable.
This method will be call repeatedly during enumeration. The index value
will always begin with 0 and increment monotonically. You don't have to
rely on the index value to determine what object to return, but you should
always check the value and start from the beginning when you see the
requested index is 0.
The `previousObject` is the object that was returned from the last call
to `nextObject` for the current iteration. This is a useful way to
manage iteration if you are tracing a linked list, for example.
Finally the context parameter will always contain a hash you can use as
a "scratchpad" to maintain any other state you need in order to iterate
properly. The context object is reused and is not reset between
iterations so make sure you setup the context with a fresh state whenever
the index parameter is 0.
Generally iterators will continue to call `nextObject` until the index
reaches the your current length-1. If you run out of data before this
time for some reason, you should simply return undefined.
The default implementation of this method simply looks up the index.

The `Ember.Freezable` mixin implements some basic methods for marking an
object as frozen. Once an object is frozen it should be read only. No changes
may be made the internal state of the object.
## Enforcement
To fully support freezing in your subclass, you must include this mixin and
override any method that might alter any property on the object to instead
raise an exception. You can check the state of an object by checking the
`isFrozen` property.
Although future versions of JavaScript may support language-level freezing
object objects, that is not the case today. Even if an object is freezable,
it is still technically possible to modify the object, even though it could
break other parts of your application that do not expect a frozen object to
change. It is, therefore, very important that you always respect the
`isFrozen` property on all freezable objects.
## Example Usage
The example below shows a simple object that implement the `Ember.Freezable`
protocol.
```javascript
Contact = Ember.Object.extend(Ember.Freezable, {
firstName: null,
lastName: null,
// swaps the names
swapNames: function() {
if (this.get('isFrozen')) throw Ember.FROZEN_ERROR;
var tmp = this.get('firstName');
this.set('firstName', this.get('lastName'));
this.set('lastName', tmp);
return this;
}
});
c = Contact.create({ firstName: "John", lastName: "Doe" });
c.swapNames(); // returns c
c.freeze();
c.swapNames(); // EXCEPTION
```
## Copying
Usually the `Ember.Freezable` protocol is implemented in cooperation with the
`Ember.Copyable` protocol, which defines a `frozenCopy()` method that will
return a frozen object, if the object implements this method as well.

Note that an Enumerable can change even if it does not implement this mixin.
For example, a MappedEnumerable cannot be directly modified but if its

## Adding Objects
To add an object to an enumerable, use the `addObject()` method. This

already present and is of a type supported by the enumerable.

tests, be sure to apply the Ember.MutableEnumerableTests to your object.

## Overview
This mixin provides properties and property observing functionality, core
features of the Ember object model.
Properties and observers allow one object to observe changes to a
property on another object. This is one of the fundamental ways that
models, controllers and views communicate with each other in an Ember
application.
Any object that has this mixin applied can be used in observer
operations. That includes `Ember.Object` and most objects you will
interact with as you write your Ember application.
Note that you will not generally apply this mixin to classes yourself,
but you will use the features provided by this module frequently, so it
is important to understand how to use it.
## Using `get()` and `set()`
Because of Ember's support for bindings and observers, you will always
access properties using the get method, and set properties using the
set method. This allows the observing objects to be notified and
computed properties to be handled properly.
More documentation about `get` and `set` are below.
## Observing Property Changes
You typically observe property changes simply by adding the `observes`
call to the end of your method declarations in classes that you write.
For example:
```javascript
Ember.Object.extend({
valueObserver: function() {
// Executes whenever the "value" property changes
}.observes('value')
});
```
Although this is the most common way to add an observer, this capability
is actually built into the `Ember.Object` class on top of two methods
defined in this mixin: `addObserver` and `removeObserver`. You can use
these two methods to add and remove observers yourself if you need to
do so at runtime.
To add an observer for a property, call:
```javascript
object.addObserver('propertyKey', targetObject, targetAction)
```
This will call the `targetAction` method on the `targetObject` whenever
the value of the `propertyKey` changes.
Note that if `propertyKey` is a computed property, the observer will be
called when any of the property dependencies are changed, even if the
resulting value of the computed property is unchanged. This is necessary
because computed properties are not computed until `get` is called.
@class Observable
@namespace Ember
*/
__exports__["default"] = Mixin.create({
/**
Retrieves the value of a property from the object.
This method is usually similar to using `object[keyName]` or `object.keyName`,
however it supports both computed properties and the unknownProperty
handler.
Because `get` unifies the syntax for accessing all these kinds
of properties, it can make many refactorings easier, such as replacing a
simple property with a computed property, or vice versa.
### Computed Properties
Computed properties are methods defined with the `property` modifier
declared at the end, such as:
```javascript
fullName: function() {
return this.get('firstName') + ' ' + this.get('lastName');
}.property('firstName', 'lastName')
```
When you call `get` on a computed property, the function will be
called and the return value will be returned instead of the function
itself.
### Unknown Properties
Likewise, if you try to call `get` on a property whose value is
`undefined`, the `unknownProperty()` method will be called on the object.
If this method returns any value other than `undefined`, it will be returned
instead. This allows you to implement "virtual" properties that are
not defined upfront.
@method get
@param {String} keyName The property to retrieve
@return {Object} The property value or undefined.
*/
get: function(keyName) {
return get(this, keyName);
},
/**
To get multiple properties at once, call `getProperties`
with a list of strings or an array:
```javascript
record.getProperties('firstName', 'lastName', 'zipCode');
// { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
```
is equivalent to:
```javascript
record.getProperties(['firstName', 'lastName', 'zipCode']);
// { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
```
@method getProperties
@param {String...|Array} list of keys to get
@return {Hash}
*/
getProperties: function() {
return apply(null, getProperties, [this].concat(slice.call(arguments)));
},
/**
Sets the provided key or path to the value.
This method is generally very similar to calling `object[key] = value` or
`object.key = value`, except that it provides support for computed
properties, the `setUnknownProperty()` method and property observers.
### Computed Properties
If you try to set a value on a key that has a computed property handler
defined (see the `get()` method for an example), then `set()` will call
that method, passing both the value and key instead of simply changing
the value itself. This is useful for those times when you need to
implement a property that is composed of one or more member
properties.
### Unknown Properties
If you try to set a value on a key that is undefined in the target
object, then the `setUnknownProperty()` handler will be called instead. This
gives you an opportunity to implement complex "virtual" properties that
are not predefined on the object. If `setUnknownProperty()` returns
undefined, then `set()` will simply set the value on the object.
### Property Observers
In addition to changing the property, `set()` will also register a property
change with the object. Unless you have placed this call inside of a
`beginPropertyChanges()` and `endPropertyChanges(),` any "local" observers
(i.e. observer methods declared on the same object), will be called
immediately. Any "remote" observers (i.e. observer methods declared on
another object) will be placed in a queue and called at a later time in a
coalesced manner.
### Chaining
In addition to property changes, `set()` returns the value of the object
itself so you can do chaining like this:
```javascript
record.set('firstName', 'Charles').set('lastName', 'Jolley');
```
@method set
@param {String} keyName The property to set
@param {Object} value The value to set or `null`.
@return {Ember.Observable}
*/

set(this, keyName, value);
return this;
},
/**

a single `beginPropertyChanges` and `endPropertyChanges` batch, so
observers will be buffered.

@param {Hash} hash the hash of keys and values to set

Adds an observer on a property.
This is the core method used to register an observer for a property.
Once you call this method, any time the key's value is set, your observer
will be notified. Note that the observers are triggered any time the
value is set, regardless of whether it has actually changed. Your
observer should be prepared to handle that.
You can also pass an optional context parameter to this method. The
context will be passed to your observer method whenever it is triggered.
Note that if you add the same target/method pair on a key multiple times
with different context parameters, your observer will only be called once
with the last context you passed.
### Observer Methods
Observer methods you pass should generally have the following signature if
you do not pass a `context` parameter:
```javascript
fooDidChange: function(sender, key, value, rev) { };
```
The sender is the object that changed. The key is the property that
changes. The value property is currently reserved and unused. The rev
is the last property revision of the object when it changed, which you can
use to detect if the key value has really changed or not.
If you pass a `context` parameter, the context will be passed before the
revision like so:
```javascript
fooDidChange: function(sender, key, value, context, rev) { };
```
Usually you will not need the value, context or revision parameters at
the end. In this case, it is common to write observer methods that take
only a sender and key value as parameters or, if you aren't interested in
any of these values, to write an observer that has no parameters at all.

@param {String} key The key to observer

`Ember.SortableMixin` provides a standard interface for array proxies
to specify a sort order and maintain this sorting when objects are added,
removed, or updated without changing the implicit order of their underlying
modelarray:
```javascript
songs = [
{trackNumber: 4, title: 'Ob-La-Di, Ob-La-Da'},
{trackNumber: 2, title: 'Back in the U.S.S.R.'},
{trackNumber: 3, title: 'Glass Onion'},
];
songsController = Ember.ArrayController.create({
model: songs,
sortProperties: ['trackNumber'],
sortAscending: true
});
songsController.get('firstObject'); // {trackNumber: 2, title: 'Back in the U.S.S.R.'}
songsController.addObject({trackNumber: 1, title: 'Dear Prudence'});
songsController.get('firstObject'); // {trackNumber: 1, title: 'Dear Prudence'}
```
If you add or remove the properties to sort by or change the sort direction the model
sort order will be automatically updated.
```javascript
songsController.set('sortProperties', ['title']);
songsController.get('firstObject'); // {trackNumber: 2, title: 'Back in the U.S.S.R.'}
songsController.toggleProperty('sortAscending');
songsController.get('firstObject'); // {trackNumber: 4, title: 'Ob-La-Di, Ob-La-Da'}
```
SortableMixin works by sorting the arrangedContent array, which is the array that
arrayProxy displays. Due to the fact that the underlying 'content' array is not changed, that
array will not display the sorted list:
```javascript
songsController.get('content').get('firstObject'); // Returns the unsorted original content
songsController.get('firstObject'); // Returns the sorted content.
```
Although the sorted content can also be accessed through the arrangedContent property,
it is preferable to use the proxied class and not the arrangedContent array directly.

An ArrayProxy wraps any other object that implements `Ember.Array` and/or
`Ember.MutableArray,` forwarding all requests. This makes it very useful for
a number of binding use cases or other cases where being able to swap
out the underlying array is useful.
A simple example of usage:
```javascript
var pets = ['dog', 'cat', 'fish'];
var ap = Ember.ArrayProxy.create({ content: Ember.A(pets) });
ap.get('firstObject'); // 'dog'
ap.set('content', ['amoeba', 'paramecium']);
ap.get('firstObject'); // 'amoeba'
```
This class can also be useful as a layer to transform the contents of
an array, as they are accessed. This can be done by overriding
`objectAtContent`:
```javascript
var pets = ['dog', 'cat', 'fish'];
var ap = Ember.ArrayProxy.create({
content: Ember.A(pets),
objectAtContent: function(idx) {
return this.get('content').objectAt(idx).toUpperCase();
}
});

NOTE: If you do override `init` for a framework class like `Ember.View` or
`Ember.ArrayController`, be sure to call `this._super()` in your
`init` declaration! If you don't, Ember may not have an opportunity to
do important setup work, and you'll see strange behavior in your
application.
@method init
*/
init: function() {},
/**
Defines the properties that will be concatenated from the superclass
(instead of overridden).
By default, when you extend an Ember class a property defined in
the subclass overrides a property with the same name that is defined
in the superclass. However, there are some cases where it is preferable
to build up a property's value by combining the superclass' property
value with the subclass' value. An example of this in use within Ember
is the `classNames` property of `Ember.View`.
Here is some sample code showing the difference between a concatenated
property and a normal one:
```javascript
App.BarView = Ember.View.extend({
someNonConcatenatedProperty: ['bar'],
classNames: ['bar']
});
App.FooBarView = App.BarView.extend({
someNonConcatenatedProperty: ['foo'],
classNames: ['foo']
});
var fooBarView = App.FooBarView.create();
fooBarView.get('someNonConcatenatedProperty'); // ['foo']
fooBarView.get('classNames'); // ['ember-view', 'bar', 'foo']
```
This behavior extends to object creation as well. Continuing the
above example:
```javascript
var view = App.FooBarView.create({
someNonConcatenatedProperty: ['baz'],
classNames: ['baz']
})
view.get('someNonConcatenatedProperty'); // ['baz']
view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
```
Adding a single property that is not an array will just add it in the array:
```javascript
var view = App.FooBarView.create({
classNames: 'baz'
})
view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
```
Using the `concatenatedProperties` property, we can tell to Ember that mix
the content of the properties.
In `Ember.View` the `classNameBindings` and `attributeBindings` properties
are also concatenated, in addition to `classNames`.
This feature is available for you to use throughout the Ember object model,
although typical app developers are likely to use it infrequently. Since
it changes expectations about behavior of properties, you should properly
document its usage in each individual concatenated property (to not
mislead your users to think they can override the property in a subclass).

/**
Creates a new subclass.
```javascript
App.Person = Ember.Object.extend({
say: function(thing) {
alert(thing);
}
});
```
This defines a new subclass of Ember.Object: `App.Person`. It contains one method: `say()`.
You can also create a subclass from any existing class by calling its `extend()` method. For example, you might want to create a subclass of Ember's built-in `Ember.View` class:
```javascript
App.PersonView = Ember.View.extend({
tagName: 'li',
classNameBindings: ['isAdministrator']
});
```
When defining a subclass, you can override methods but still access the implementation of your parent class by calling the special `_super()` method:
```javascript
App.Person = Ember.Object.extend({
say: function(thing) {
var name = this.get('name');
alert(name + ' says: ' + thing);
}
});
App.Soldier = App.Person.extend({
say: function(thing) {
this._super(thing + ", sir!");
},
march: function(numberOfHours) {
alert(this.get('name') + ' marches for ' + numberOfHours + ' hours.')
}
});
var yehuda = App.Soldier.create({
name: "Yehuda Katz"
});
yehuda.say("Yes"); // alerts "Yehuda Katz says: Yes, sir!"
```
The `create()` on line #17 creates an *instance* of the `App.Soldier` class. The `extend()` on line #8 creates a *subclass* of `App.Person`. Any instance of the `App.Person` class will *not* have the `march()` method.
You can also pass `Mixin` classes to add additional properties to the subclass.
```javascript
App.Person = Ember.Object.extend({
say: function(thing) {
alert(this.get('name') + ' says: ' + thing);
}
});
App.SingingMixin = Mixin.create({
sing: function(thing){
alert(this.get('name') + ' sings: la la la ' + thing);
}
});
App.BroadwayStar = App.Person.extend(App.SingingMixin, {
dance: function() {
alert(this.get('name') + ' dances: tap tap tap tap ');
}
});
```
The `App.BroadwayStar` class contains three methods: `say()`, `sing()`, and `dance()`.

In some cases, you may want to annotate computed properties with additional
metadata about how they function or what values they operate on. For
example, computed property functions may close over variables that are then
no longer available for introspection.
You can pass a hash of these values to a computed property like this:
```javascript
person: function() {
var personId = this.get('personId');
return App.Person.create({ id: personId });
}.property().meta({ type: App.Person })
```
Once you've done this, you can retrieve the values saved to the computed
property from your class like this:
```javascript
MyClass.metaForProperty('person');
```
This will return the original hash that was passed to `meta()`.

`Ember.ObjectProxy` forwards all properties not defined by the proxy itself
to a proxied `content` object.
```javascript
object = Ember.Object.create({
name: 'Foo'
});
proxy = Ember.ObjectProxy.create({
content: object
});
// Access and change existing properties
proxy.get('name') // 'Foo'

object.get('name') // 'Bar'
// Create new 'description' property on `object`
proxy.set('description', 'Foo is a whizboo baz');
object.get('description') // 'Foo is a whizboo baz'
```
While `content` is unset, setting a property to be delegated will throw an
Error.
```javascript
proxy = Ember.ObjectProxy.create({

proxy.get('flag'); // true
proxy.get('foo'); // undefined
proxy.set('foo', 'data'); // throws Error

Delegated properties can be bound to and will change when content is updated.
Computed properties on the proxy itself can depend on delegated properties.
```javascript

var firstName = this.get('firstName'),
lastName = this.get('lastName');

/**
An unordered collection of objects.
A Set works a bit like an array except that its items are not ordered. You
can create a set to efficiently test for membership for an object. You can
also iterate through a set just like an array, even accessing objects by
index, however there is no guarantee as to their order.
All Sets are observable via the Enumerable Observer API - which works
on any enumerable object including both Sets and Arrays.
## Creating a Set
You can create a set like you would most objects using
`new Ember.Set()`. Most new sets you create will be empty, but you can
also initialize the set with some content by passing an array or other
enumerable of objects to the constructor.
Finally, you can pass in an existing set and the set will be copied. You
can also create a copy of a set by calling `Ember.Set#copy()`.
```javascript
// creates a new empty set
var foundNames = new Ember.Set();
// creates a set with four names in it.
var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P
// creates a copy of the names set.
var namesCopy = new Ember.Set(names);
// same as above.
var anotherNamesCopy = names.copy();
```
## Adding/Removing Objects
You generally add or remove objects from a set using `add()` or
`remove()`. You can add any type of object including primitives such as
numbers, strings, and booleans.
Unlike arrays, objects can only exist one time in a set. If you call `add()`
on a set with the same object multiple times, the object will only be added
once. Likewise, calling `remove()` with the same object multiple times will
remove the object the first time and have no effect on future calls until
you add the object to the set again.
NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do
so will be ignored.
In addition to add/remove you can also call `push()`/`pop()`. Push behaves
just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary
object, remove it and return it. This is a good way to use a set as a job
queue when you don't care which order the jobs are executed in.
## Testing for an Object
To test for an object's presence in a set you simply call
`Ember.Set#contains()`.
## Observing changes
When using `Ember.Set`, you can observe the `"[]"` property to be
alerted whenever the content changes. You can also add an enumerable
observer to the set to be notified of specific objects that are added and
removed from the set. See [Ember.Enumerable](/api/classes/Ember.Enumerable.html)
for more information on enumerables.
This is often unhelpful. If you are filtering sets of objects, for instance,
it is very inefficient to re-filter all of the items each time the set
changes. It would be better if you could just adjust the filtered set based
on what was changed on the original set. The same issue applies to merging
sets, as well.
## Other Methods
`Ember.Set` primary implements other mixin APIs. For a complete reference
on the methods you will use with `Ember.Set`, please consult these mixins.
The most useful ones will be `Ember.Enumerable` and
`Ember.MutableEnumerable` which implement most of the common iterator
methods you are used to on Array.
Note that you can also use the `Ember.Copyable` and `Ember.Freezable`
APIs on `Ember.Set` as well. Once a set is frozen it can no longer be
modified. The benefit of this is that when you call `frozenCopy()` on it,
Ember will avoid making copies of the set. This allows you to write
code that can know with certainty when the underlying set data will or
will not be modified.

sent with the action: the view's context.

choice. This mixin is most often useful when you are doing more complex
event handling in custom View subclasses.

this.triggerAction(); // Sends the `save` action, along with the current context

/**
`Ember.CollectionView` is an `Ember.View` descendent responsible for managing
a collection (an array or array-like object) by maintaining a child view object
and associated DOM representation for each item in the array and ensuring
that child views and their associated rendered HTML are updated when items in
the array are added, removed, or replaced.
## Setting content
The managed collection of objects is referenced as the `Ember.CollectionView`
instance's `content` property.
```javascript
someItemsView = Ember.CollectionView.create({
content: ['A', 'B','C']
})
```
The view for each item in the collection will have its `content` property set
to the item.
## Specifying itemViewClass
By default the view class for each item in the managed collection will be an
instance of `Ember.View`. You can supply a different class by setting the
`CollectionView`'s `itemViewClass` property.
Given an empty `<body>` and the following code:
```javascript
someItemsView = Ember.CollectionView.create({
classNames: ['a-collection'],
content: ['A','B','C'],
itemViewClass: Ember.View.extend({
template: Ember.Handlebars.compile("the letter: {{view.content}}")
})
});
someItemsView.appendTo('body');
```
Will result in the following HTML structure
```html
<div class="ember-view a-collection">
<div class="ember-view">the letter: A</div>
<div class="ember-view">the letter: B</div>
<div class="ember-view">the letter: C</div>
</div>
```
## Automatic matching of parent/child tagNames
Setting the `tagName` property of a `CollectionView` to any of
"ul", "ol", "table", "thead", "tbody", "tfoot", "tr", or "select" will result
in the item views receiving an appropriately matched `tagName` property.
Given an empty `<body>` and the following code:
```javascript
anUnorderedListView = Ember.CollectionView.create({
tagName: 'ul',
content: ['A','B','C'],
itemViewClass: Ember.View.extend({
template: Ember.Handlebars.compile("the letter: {{view.content}}")
})
});
anUnorderedListView.appendTo('body');
```
Will result in the following HTML structure
```html
<ul class="ember-view a-collection">
<li class="ember-view">the letter: A</li>
<li class="ember-view">the letter: B</li>
<li class="ember-view">the letter: C</li>
</ul>
```
Additional `tagName` pairs can be provided by adding to
`Ember.CollectionView.CONTAINER_MAP `
```javascript
Ember.CollectionView.CONTAINER_MAP['article'] = 'section'
```
## Programmatic creation of child views
For cases where additional customization beyond the use of a single
`itemViewClass` or `tagName` matching is required CollectionView's
`createChildView` method can be overidden:
```javascript
CustomCollectionView = Ember.CollectionView.extend({
createChildView: function(viewClass, attrs) {
if (attrs.content.kind == 'album') {
viewClass = App.AlbumView;
} else {
viewClass = App.SongView;
}
return this._super(viewClass, attrs);
}
});
```
## Empty View
You can provide an `Ember.View` subclass to the `Ember.CollectionView`
instance as its `emptyView` property. If the `content` property of a
`CollectionView` is set to `null` or an empty array, an instance of this view
will be the `CollectionView`s only child.
```javascript
aListWithNothing = Ember.CollectionView.create({
classNames: ['nothing']
content: null,
emptyView: Ember.View.extend({
template: Ember.Handlebars.compile("The collection is empty")
})
});
aListWithNothing.appendTo('body');
```
Will result in the following HTML structure
```html
<div class="ember-view nothing">
<div class="ember-view">
The collection is empty
</div>
</div>
```
## Adding and Removing items
The `childViews` property of a `CollectionView` should not be directly
manipulated. Instead, add, remove, replace items from its `content` property.
This will trigger appropriate changes to its rendered HTML.

/**
An `Ember.Component` is a view that is completely
isolated. Property access in its templates go
to the view object and actions are targeted at
the view object. There is no access to the
surrounding context or outer controller; all
contextual information must be passed in.
The easiest way to create an `Ember.Component` is via
a template. If you name a template
`components/my-foo`, you will be able to use
`{{my-foo}}` in other templates, which will make
an instance of the isolated component.
```handlebars
{{app-profile person=currentUser}}
```
```handlebars
<!-- app-profile template -->
<h1>{{person.title}}</h1>
<img {{bind-attr src=person.avatar}}>
<p class='signature'>{{person.signature}}</p>
```
You can use `yield` inside a template to
include the **contents** of any block attached to
the component. The block will be executed in the
context of the surrounding context or outer controller:
```handlebars
{{#app-profile person=currentUser}}
<p>Admin mode</p>
{{! Executed in the controller's context. }}
{{/app-profile}}
```
```handlebars
<!-- app-profile template -->
<h1>{{person.title}}</h1>
{{! Executed in the components context. }}
{{yield}} {{! block contents }}
```
If you want to customize the component, in order to
handle events or actions, you implement a subclass
of `Ember.Component` named after the name of the
component. Note that `Component` needs to be appended to the name of
your subclass like `AppProfileComponent`.
For example, you could implement the action
`hello` for the `app-profile` component:
```javascript
App.AppProfileComponent = Ember.Component.extend({
actions: {
hello: function(name) {
console.log("Hello", name);
}
}
});
```
And then use it in the component's template:
```handlebars
<!-- app-profile template -->
<h1>{{person.title}}</h1>
{{yield}} <!-- block contents -->
<button {{action 'hello' person.name}}>
Say Hello to {{person.name}}
</button>
```
Components must have a `-` in their name to avoid
conflicts with built-in controls that wrap HTML
elements. This is consistent with the same
requirement in web components.

Triggers a named action on the controller context where the component is used if
this controller has registered for notifications of the action.
For example a component for playing or pausing music may translate click events
into action notifications of "play" or "stop" depending on some internal state
of the component:
```javascript
App.PlayButtonComponent = Ember.Component.extend({
click: function(){
if (this.get('isPlaying')) {
this.sendAction('play');
} else {
this.sendAction('stop');
}
}
});
```
When used inside a template these component actions are configured to
trigger actions in the outer application context:
```handlebars
{{! application.hbs }}
{{play-button play="musicStarted" stop="musicStopped"}}
```
When the component receives a browser `click` event it translate this
interaction into application-specific semantics ("play" or "stop") and
triggers the specified action name on the controller for the template
where the component is used:
```javascript
App.ApplicationController = Ember.Controller.extend({
actions: {
musicStarted: function(){
// called when the play button is clicked
// and the music started playing
},
musicStopped: function(){
// called when the play button is clicked
// and the music stopped playing
}
}
});
```
If no action name is passed to `sendAction` a default name of "action"
is assumed.
```javascript
App.NextButtonComponent = Ember.Component.extend({
click: function(){
this.sendAction();
}
});
```
```handlebars
{{! application.hbs }}
{{next-button action="playNextSongInAlbum"}}
```
```javascript
App.ApplicationController = Ember.Controller.extend({
actions: {
playNextSongInAlbum: function(){
...
}
}
});

/**
A `ContainerView` is an `Ember.View` subclass that implements `Ember.MutableArray`
allowing programmatic management of its child views.
## Setting Initial Child Views
The initial array of child views can be set in one of two ways. You can
provide a `childViews` property at creation time that contains instance of
`Ember.View`:
```javascript
aContainer = Ember.ContainerView.create({
childViews: [Ember.View.create(), Ember.View.create()]
});
```
You can also provide a list of property names whose values are instances of
`Ember.View`:
```javascript
aContainer = Ember.ContainerView.create({
childViews: ['aView', 'bView', 'cView'],
aView: Ember.View.create(),
bView: Ember.View.create(),
cView: Ember.View.create()
});
```
The two strategies can be combined:
```javascript
aContainer = Ember.ContainerView.create({
childViews: ['aView', Ember.View.create()],
aView: Ember.View.create()
});
```
Each child view's rendering will be inserted into the container's rendered
HTML in the same order as its position in the `childViews` property.
## Adding and Removing Child Views
The container view implements `Ember.MutableArray` allowing programmatic management of its child views.
To remove a view, pass that view into a `removeObject` call on the container view.
Given an empty `<body>` the following code
```javascript
aContainer = Ember.ContainerView.create({
classNames: ['the-container'],
childViews: ['aView', 'bView'],
aView: Ember.View.create({
template: Ember.Handlebars.compile("A")
}),
bView: Ember.View.create({
template: Ember.Handlebars.compile("B")
})
});
aContainer.appendTo('body');
```
Results in the HTML
```html
<div class="ember-view the-container">
<div class="ember-view">A</div>
<div class="ember-view">B</div>
</div>
```
Removing a view
```javascript
aContainer.toArray(); // [aContainer.aView, aContainer.bView]
aContainer.removeObject(aContainer.get('bView'));
aContainer.toArray(); // [aContainer.aView]
```
Will result in the following HTML
```html
<div class="ember-view the-container">
<div class="ember-view">A</div>
</div>
```
Similarly, adding a child view is accomplished by adding `Ember.View` instances to the
container view.
Given an empty `<body>` the following code
```javascript
aContainer = Ember.ContainerView.create({
classNames: ['the-container'],
childViews: ['aView', 'bView'],
aView: Ember.View.create({
template: Ember.Handlebars.compile("A")
}),
bView: Ember.View.create({
template: Ember.Handlebars.compile("B")
})
});
aContainer.appendTo('body');
```
Results in the HTML
```html
<div class="ember-view the-container">
<div class="ember-view">A</div>
<div class="ember-view">B</div>
</div>
```
Adding a view
```javascript
AnotherViewClass = Ember.View.extend({
template: Ember.Handlebars.compile("Another view")
});
aContainer.toArray(); // [aContainer.aView, aContainer.bView]
aContainer.pushObject(AnotherViewClass.create());
aContainer.toArray(); // [aContainer.aView, aContainer.bView, <AnotherViewClass instance>]
```
Will result in the following HTML
```html
<div class="ember-view the-container">
<div class="ember-view">A</div>
<div class="ember-view">B</div>
<div class="ember-view">Another view</div>
</div>
```
## Templates and Layout
A `template`, `templateName`, `defaultTemplate`, `layout`, `layoutName` or
`defaultLayout` property on a container view will not result in the template
or layout being rendered. The HTML contents of a `Ember.ContainerView`'s DOM
representation will only be the rendered HTML of its child views.

/**
`Ember.View` is the class in Ember responsible for encapsulating templates of
HTML content, combining templates with data to render as sections of a page's
DOM, and registering and responding to user-initiated events.
## HTML Tag
The default HTML tag name used for a view's DOM representation is `div`. This
can be customized by setting the `tagName` property. The following view
class:
```javascript
ParagraphView = Ember.View.extend({
tagName: 'em'
});
```
Would result in instances with the following HTML:
```html
<em id="ember1" class="ember-view"></em>
```
## HTML `class` Attribute
The HTML `class` attribute of a view's tag can be set by providing a
`classNames` property that is set to an array of strings:
```javascript
MyView = Ember.View.extend({
classNames: ['my-class', 'my-other-class']
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view my-class my-other-class"></div>
```
`class` attribute values can also be set by providing a `classNameBindings`
property set to an array of properties names for the view. The return value
of these properties will be added as part of the value for the view's `class`
attribute. These properties can be computed properties:
```javascript
MyView = Ember.View.extend({
classNameBindings: ['propertyA', 'propertyB'],
propertyA: 'from-a',
propertyB: function() {
if (someLogic) { return 'from-b'; }
}.property()
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view from-a from-b"></div>
```
If the value of a class name binding returns a boolean the property name
itself will be used as the class name if the property is true. The class name
will not be added if the value is `false` or `undefined`.
```javascript
MyView = Ember.View.extend({
classNameBindings: ['hovered'],
hovered: true
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view hovered"></div>
```
When using boolean class name bindings you can supply a string value other
than the property name for use as the `class` HTML attribute by appending the
preferred value after a ":" character when defining the binding:
```javascript
MyView = Ember.View.extend({
classNameBindings: ['awesome:so-very-cool'],
awesome: true
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view so-very-cool"></div>
```
Boolean value class name bindings whose property names are in a
camelCase-style format will be converted to a dasherized format:
```javascript
MyView = Ember.View.extend({
classNameBindings: ['isUrgent'],
isUrgent: true
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view is-urgent"></div>
```
Class name bindings can also refer to object values that are found by
traversing a path relative to the view itself:
```javascript
MyView = Ember.View.extend({
classNameBindings: ['messages.empty']
messages: Ember.Object.create({
empty: true
})
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view empty"></div>
```
If you want to add a class name for a property which evaluates to true and
and a different class name if it evaluates to false, you can pass a binding
like this:
```javascript
// Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false
Ember.View.extend({
classNameBindings: ['isEnabled:enabled:disabled']
isEnabled: true
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view enabled"></div>
```
When isEnabled is `false`, the resulting HTML reprensentation looks like
this:
```html
<div id="ember1" class="ember-view disabled"></div>
```
This syntax offers the convenience to add a class if a property is `false`:
```javascript
// Applies no class when isEnabled is true and class 'disabled' when isEnabled is false
Ember.View.extend({
classNameBindings: ['isEnabled::disabled']
isEnabled: true
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view"></div>
```
When the `isEnabled` property on the view is set to `false`, it will result
in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view disabled"></div>
```
Updates to the the value of a class name binding will result in automatic
update of the HTML `class` attribute in the view's rendered HTML
representation. If the value becomes `false` or `undefined` the class name
will be removed.
Both `classNames` and `classNameBindings` are concatenated properties. See
[Ember.Object](/api/classes/Ember.Object.html) documentation for more
information about concatenated properties.
## HTML Attributes
The HTML attribute section of a view's tag can be set by providing an
`attributeBindings` property set to an array of property names on the view.
The return value of these properties will be used as the value of the view's
HTML associated attribute:
```javascript
AnchorView = Ember.View.extend({
tagName: 'a',
attributeBindings: ['href'],
href: 'http://google.com'
});
```
Will result in view instances with an HTML representation of:
```html
<a id="ember1" class="ember-view" href="http://google.com"></a>
```
One property can be mapped on to another by placing a ":" between
the source property and the destination property:
```javascript
AnchorView = Ember.View.extend({
tagName: 'a',
attributeBindings: ['url:href'],
url: 'http://google.com'
});
```
Will result in view instances with an HTML representation of:
```html
<a id="ember1" class="ember-view" href="http://google.com"></a>
```
If the return value of an `attributeBindings` monitored property is a boolean
the property will follow HTML's pattern of repeating the attribute's name as
its value:
```javascript
MyTextInput = Ember.View.extend({
tagName: 'input',
attributeBindings: ['disabled'],
disabled: true
});
```
Will result in view instances with an HTML representation of:
```html
<input id="ember1" class="ember-view" disabled="disabled" />
```
`attributeBindings` can refer to computed properties:
```javascript
MyTextInput = Ember.View.extend({
tagName: 'input',
attributeBindings: ['disabled'],
disabled: function() {
if (someLogic) {
return true;
} else {
return false;
}
}.property()
});
```
Updates to the the property of an attribute binding will result in automatic
update of the HTML attribute in the view's rendered HTML representation.
`attributeBindings` is a concatenated property. See [Ember.Object](/api/classes/Ember.Object.html)
documentation for more information about concatenated properties.
## Templates
The HTML contents of a view's rendered representation are determined by its
template. Templates can be any function that accepts an optional context
parameter and returns a string of HTML that will be inserted within the
view's tag. Most typically in Ember this function will be a compiled
`Ember.Handlebars` template.
```javascript
AView = Ember.View.extend({
template: Ember.Handlebars.compile('I am the template')
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view">I am the template</div>
```
Within an Ember application is more common to define a Handlebars templates as
part of a page:
```html
<script type='text/x-handlebars' data-template-name='some-template'>
Hello
</script>
```
And associate it by name using a view's `templateName` property:
```javascript
AView = Ember.View.extend({
templateName: 'some-template'
});
```
If you have nested resources, your Handlebars template will look like this:
```html
<script type='text/x-handlebars' data-template-name='posts/new'>
<h1>New Post</h1>
</script>
```
And `templateName` property:
```javascript
AView = Ember.View.extend({
templateName: 'posts/new'
});
```
Using a value for `templateName` that does not have a Handlebars template
with a matching `data-template-name` attribute will throw an error.
For views classes that may have a template later defined (e.g. as the block
portion of a `{{view}}` Handlebars helper call in another template or in
a subclass), you can provide a `defaultTemplate` property set to compiled
template function. If a template is not later provided for the view instance
the `defaultTemplate` value will be used:
```javascript
AView = Ember.View.extend({
defaultTemplate: Ember.Handlebars.compile('I was the default'),
template: null,
templateName: null
});
```
Will result in instances with an HTML representation of:
```html
<div id="ember1" class="ember-view">I was the default</div>
```
If a `template` or `templateName` is provided it will take precedence over
`defaultTemplate`:
```javascript
AView = Ember.View.extend({
defaultTemplate: Ember.Handlebars.compile('I was the default')
});
aView = AView.create({
template: Ember.Handlebars.compile('I was the template, not default')
});
```
Will result in the following HTML representation when rendered:
```html
<div id="ember1" class="ember-view">I was the template, not default</div>
```
## View Context
The default context of the compiled template is the view's controller:
```javascript
AView = Ember.View.extend({
template: Ember.Handlebars.compile('Hello {{excitedGreeting}}')
});
aController = Ember.Object.create({
firstName: 'Barry',
excitedGreeting: function() {
return this.get("content.firstName") + "!!!"
}.property()
});
aView = AView.create({
controller: aController
});
```
Will result in an HTML representation of:
```html
<div id="ember1" class="ember-view">Hello Barry!!!</div>
```
A context can also be explicitly supplied through the view's `context`
property. If the view has neither `context` nor `controller` properties, the
`parentView`'s context will be used.
## Layouts
Views can have a secondary template that wraps their main template. Like
primary templates, layouts can be any function that accepts an optional
context parameter and returns a string of HTML that will be inserted inside
view's tag. Views whose HTML element is self closing (e.g. `<input />`)
cannot have a layout and this property will be ignored.
Most typically in Ember a layout will be a compiled `Ember.Handlebars`
template.
A view's layout can be set directly with the `layout` property or reference
an existing Handlebars template by name with the `layoutName` property.
A template used as a layout must contain a single use of the Handlebars
`{{yield}}` helper. The HTML contents of a view's rendered `template` will be
inserted at this location:
```javascript
AViewWithLayout = Ember.View.extend({
layout: Ember.Handlebars.compile("<div class='my-decorative-class'>{{yield}}</div>"),
template: Ember.Handlebars.compile("I got wrapped")
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view">
<div class="my-decorative-class">
I got wrapped
</div>
</div>
```
See [Ember.Handlebars.helpers.yield](/api/classes/Ember.Handlebars.helpers.html#method_yield)
for more information.
## Responding to Browser Events
Views can respond to user-initiated events in one of three ways: method
implementation, through an event manager, and through `{{action}}` helper use
in their template or layout.
### Method Implementation
Views can respond to user-initiated events by implementing a method that
matches the event name. A `jQuery.Event` object will be passed as the
argument to this method.
```javascript
AView = Ember.View.extend({
click: function(event) {
// will be called when when an instance's
// rendered element is clicked
}
});
```
### Event Managers
Views can define an object as their `eventManager` property. This object can
then implement methods that match the desired event names. Matching events
that occur on the view's rendered HTML or the rendered HTML of any of its DOM
descendants will trigger this method. A `jQuery.Event` object will be passed
as the first argument to the method and an `Ember.View` object as the
second. The `Ember.View` will be the view whose rendered HTML was interacted
with. This may be the view with the `eventManager` property or one of its
descendent views.
```javascript
AView = Ember.View.extend({
eventManager: Ember.Object.create({
doubleClick: function(event, view) {
// will be called when when an instance's
// rendered element or any rendering
// of this views's descendent
// elements is clicked
}
})
});
```
An event defined for an event manager takes precedence over events of the
same name handled through methods on the view.
```javascript
AView = Ember.View.extend({
mouseEnter: function(event) {
// will never trigger.
},
eventManager: Ember.Object.create({
mouseEnter: function(event, view) {
// takes precedence over AView#mouseEnter
}
})
});
```
Similarly a view's event manager will take precedence for events of any views
rendered as a descendent. A method name that matches an event name will not
be called if the view instance was rendered inside the HTML representation of
a view that has an `eventManager` property defined that handles events of the
name. Events not handled by the event manager will still trigger method calls
on the descendent.
```javascript
OuterView = Ember.View.extend({
template: Ember.Handlebars.compile("outer {{#view InnerView}}inner{{/view}} outer"),
eventManager: Ember.Object.create({
mouseEnter: function(event, view) {
// view might be instance of either
// OuterView or InnerView depending on
// where on the page the user interaction occured
}
})
});
InnerView = Ember.View.extend({
click: function(event) {
// will be called if rendered inside
// an OuterView because OuterView's
// eventManager doesn't handle click events
},
mouseEnter: function(event) {
// will never be called if rendered inside
// an OuterView.
}
});
```
### Handlebars `{{action}}` Helper
See [Handlebars.helpers.action](/api/classes/Ember.Handlebars.helpers.html#method_action).
### Event Names
All of the event handling approaches described above respond to the same set
of events. The names of the built-in events are listed below. (The hash of
built-in events exists in `Ember.EventDispatcher`.) Additional, custom events
can be registered by using `Ember.Application.customEvents`.
Touch events:
* `touchStart`
* `touchMove`
* `touchEnd`
* `touchCancel`
Keyboard events
* `keyDown`
* `keyUp`
* `keyPress`
Mouse events
* `mouseDown`
* `mouseUp`
* `contextMenu`
* `click`
* `doubleClick`
* `mouseMove`
* `focusIn`
* `focusOut`
* `mouseEnter`
* `mouseLeave`
Form events:
* `submit`
* `change`
* `focusIn`
* `focusOut`
* `input`
HTML5 drag and drop events:
* `dragStart`
* `drag`
* `dragEnter`
* `dragLeave`
* `dragOver`
* `dragEnd`
* `drop`
## Handlebars `{{view}}` Helper
Other `Ember.View` instances can be included as part of a view's template by
using the `{{view}}` Handlebars helper. See [Ember.Handlebars.helpers.view](/api/classes/Ember.Handlebars.helpers.html#method_view)
for additional information.

For example, consider the following tree of handlers. Each handler is

```

Consider the following transitions:
1. A URL transition to `/posts/1`.
1. Triggers the `*model` callbacks on the
`index`, `posts`, and `showPost` handlers
2. Triggers the `enter` callback on the same
3. Triggers the `setup` callback on the same
2. A direct transition to `newPost`
1. Triggers the `exit` callback on `showPost`
2. Triggers the `enter` callback on `newPost`
3. Triggers the `setup` callback on `newPost`
3. A direct transition to `about` with a specified
context object
1. Triggers the `exit` callback on `newPost`
and `posts`
2. Triggers the `serialize` callback on `about`
3. Triggers the `enter` callback on `about`
4. Triggers the `setup` callback on `about`

which handlers are newly active, and which handlers remain
active but have their context changed.
Take a list of old handlers and new handlers and partition
them into four buckets:
* unchanged: the handler was active in both the old and
new URL, and its context remains the same
* updated context: the handler was active in both the
old and new URL, but its context changed. The handler's
`setup` method, if any, will be called with the new
context.
* exited: the handler was active in the old URL, but is
no longer active.
* entered: the handler was not active in the old URL, but
is now active.

* `updatedContext`: a list of `HandlerInfo` objects that
represent handlers that remain active but have a changed
context
* `entered`: a list of `HandlerInfo` objects that represent
handlers that are newly active
* `exited`: a list of `HandlerInfo` objects that are no
longer active.
* `unchanged`: a list of `HanderInfo` objects that remain active.

/**
`RSVP.allSettled` is similar to `RSVP.all`, but instead of implementing
a fail-fast method, it waits until all the promises have returned and
shows you all the results. This is useful if you want to handle multiple
promises' failure states together as a set.
Returns a promise that is fulfilled when all the given promises have been
settled. The return promise is fulfilled with an array of the states of
the promises passed into the `promises` array argument.
Each state object will either indicate fulfillment or rejection, and
provide the corresponding value or reason. The states will take one of
the following formats:
```javascript
{ state: 'fulfilled', value: value }
or
{ state: 'rejected', reason: reason }
```
Example:
```javascript
var promise1 = RSVP.Promise.resolve(1);
var promise2 = RSVP.Promise.reject(new Error('2'));
var promise3 = RSVP.Promise.reject(new Error('3'));
var promises = [ promise1, promise2, promise3 ];
RSVP.allSettled(promises).then(function(array){
// array == [
// { state: 'fulfilled', value: 1 },
// { state: 'rejected', reason: Error },
// { state: 'rejected', reason: Error }
// ]
// Note that for the second item, reason.message will be "2", and for the
// third item, reason.message will be "3".
}, function(error) {
// Not run. (This block would only be called if allSettled had failed,
// for instance if passed an incorrect argument type.)

`RSVP.filter` is similar to JavaScript's native `filter` method, except that it
waits for all promises to become fulfilled before running the `filterFn` on
each item in given to `promises`. `RSVP.filter` returns a promise that will
become fulfilled with the result of running `filterFn` on the values the
promises become fulfilled with.
For example:
```javascript
var promise1 = RSVP.resolve(1);
var promise2 = RSVP.resolve(2);
var promise3 = RSVP.resolve(3);
var promises = [promise1, promise2, promise3];
var filterFn = function(item){
return item > 1;
};
RSVP.filter(promises, filterFn).then(function(result){
// result is [ 2, 3 ]
});
```
If any of the `promises` given to `RSVP.filter` are rejected, the first promise
that is rejected will be given as an argument to the returned promise's
rejection handler. For example:
```javascript
var promise1 = RSVP.resolve(1);
var promise2 = RSVP.reject(new Error("2"));
var promise3 = RSVP.reject(new Error("3"));
var promises = [ promise1, promise2, promise3 ];
var filterFn = function(item){
return item > 1;
};
RSVP.filter(promises, filterFn).then(function(array){
// Code here never runs because there are rejected promises!
}, function(reason) {
// reason.message === "2"
});
```
`RSVP.filter` will also wait for any promises returned from `filterFn`.
For instance, you may want to fetch a list of users then return a subset
of those users based on some asynchronous operation:
```javascript
var alice = { name: 'alice' };
var bob = { name: 'bob' };
var users = [ alice, bob ];
var promises = users.map(function(user){
return RSVP.resolve(user);
});
var filterFn = function(user){
// Here, Alice has permissions to create a blog post, but Bob does not.
return getPrivilegesForUser(user).then(function(privs){
return privs.can_create_blog_post === true;
});
};
RSVP.filter(promises, filterFn).then(function(users){
// true, because the server told us only Alice can create a blog post.
users.length === 1;
// false, because Alice is the only user present in `users`
users[0] === bob;
});
```

`RSVP.hashSettled` is similar to `RSVP.allSettled`, but takes an object
instead of an array for its `promises` argument.
Unlike `RSVP.all` or `RSVP.hash`, which implement a fail-fast method,
but like `RSVP.allSettled`, `hashSettled` waits until all the
constituent promises have returned and then shows you all the results
with their states and values/reasons. This is useful if you want to
handle multiple promises' failure states together as a set.
Returns a promise that is fulfilled when all the given promises have been
settled, or rejected if the passed parameters are invalid.
The returned promise is fulfilled with a hash that has the same key names as
the `promises` object argument. If any of the values in the object are not
promises, they will be copied over to the fulfilled object and marked with state
'fulfilled'.
Example:
```javascript
var promises = {
myPromise: RSVP.Promise.resolve(1),
yourPromise: RSVP.Promise.resolve(2),
theirPromise: RSVP.Promise.resolve(3),
notAPromise: 4
};
RSVP.hashSettled(promises).then(function(hash){
// hash here is an object that looks like:
// {
// myPromise: { state: 'fulfilled', value: 1 },
// yourPromise: { state: 'fulfilled', value: 2 },
// theirPromise: { state: 'fulfilled', value: 3 },
// notAPromise: { state: 'fulfilled', value: 4 }
// }
});
```
If any of the `promises` given to `RSVP.hash` are rejected, the state will
be set to 'rejected' and the reason for rejection provided.
Example:
```javascript
var promises = {
myPromise: RSVP.Promise.resolve(1),
rejectedPromise: RSVP.Promise.reject(new Error('rejection')),
anotherRejectedPromise: RSVP.Promise.reject(new Error('more rejection'))
};
RSVP.hashSettled(promises).then(function(hash){
// hash here is an object that looks like:
// {
// myPromise: { state: 'fulfilled', value: 1 },
// rejectedPromise: { state: 'rejected', reason: Error },
// anotherRejectedPromise: { state: 'rejected', reason: Error },
// }
// Note that for rejectedPromise, reason.message == 'rejection',
// and for anotherRejectedPromise, reason.message == 'more rejection'.
});
```
An important note: `RSVP.hashSettled` is intended for plain JavaScript objects that
are just a set of keys and values. `RSVP.hashSettled` will NOT preserve prototype
chains.
Example:
```javascript
function MyConstructor(){
this.example = RSVP.Promise.resolve('Example');
}
MyConstructor.prototype = {
protoProperty: RSVP.Promise.resolve('Proto Property')
};
var myObject = new MyConstructor();
RSVP.hashSettled(myObject).then(function(hash){
// protoProperty will not be present, instead you will just have an
// object that looks like:
// {

`RSVP.denodeify` takes a "node-style" function and returns a function that
will return an `RSVP.Promise`. You can use `denodeify` in Node.js or the
browser when you'd prefer to use promises over using callbacks. For example,
`denodeify` transforms the following:
```javascript
var fs = require('fs');
fs.readFile('myfile.txt', function(err, data){
if (err) return handleError(err);
handleData(data);
});
```
into:
```javascript
var fs = require('fs');
var readFile = RSVP.denodeify(fs.readFile);
readFile('myfile.txt').then(handleData, handleError);
```
If the node function has multiple success parameters, then `denodeify`
just returns the first one:
```javascript
var request = RSVP.denodeify(require('request'));
request('http://example.com').then(function(res) {
// ...
});
```
However, if you need all success parameters, setting `denodeify`'s
second parameter to `true` causes it to return all success parameters
as an array:
```javascript
var request = RSVP.denodeify(require('request'), true);
request('http://example.com').then(function(result) {
// result[0] -> res
// result[1] -> body
});
```
Or if you pass it an array with names it returns the parameters as a hash:
```javascript
var request = RSVP.denodeify(require('request'), ['res', 'body']);
request('http://example.com').then(function(result) {
// result.res
// result.body
});
```
Sometimes you need to retain the `this`:
```javascript
var app = require('express')();
var render = RSVP.denodeify(app.render.bind(app));
```
The denodified function inherits from the original function. It works in all
environments, except IE 10 and below. Consequently all properties of the original
function are available to you. However, any properties you change on the
denodeified function won't be changed on the original function. Example:
```javascript
var request = RSVP.denodeify(require('request')),
cookieJar = request.jar(); // <- Inheritance is used here
request('http://example.com', {jar: cookieJar}).then(function(res) {
// cookieJar.cookies holds now the cookies returned by example.com
});
```
Using `denodeify` makes it easier to compose asynchronous operations instead
of using callbacks. For example, instead of:
```javascript
var fs = require('fs');
fs.readFile('myfile.txt', function(err, data){
if (err) { ... } // Handle error
fs.writeFile('myfile2.txt', data, function(err){
if (err) { ... } // Handle error
console.log('done')
});
});
```
you can chain the operations together using `then` from the returned promise:
```javascript
var fs = require('fs');
var readFile = RSVP.denodeify(fs.readFile);
var writeFile = RSVP.denodeify(fs.writeFile);
readFile('myfile.txt').then(function(data){
return writeFile('myfile2.txt', data);
}).then(function(){
console.log('done')
}).catch(function(error){
// Handle error
});
```

@param {Boolean|Array} argumentNames An optional paramter that if set
to `true` causes the promise to fulfill with the callback's success arguments
as an array. This is useful if the node function has multiple success
paramters. If you set this paramter to an array with names, the promise will
fulfill with a hash with these names as keys and the success parameters as
values.

/**
Promise objects represent the eventual result of an asynchronous operation. The
primary way of interacting with a promise is through its `then` method, which
registers callbacks to receive either a promise’s eventual value or the reason
why the promise cannot be fulfilled.
Terminology
-----------
- `promise` is an object or function with a `then` method whose behavior conforms to this specification.
- `thenable` is an object or function that defines a `then` method.
- `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
- `exception` is a value that is thrown using the throw statement.
- `reason` is a value that indicates why a promise was rejected.
- `settled` the final resting state of a promise, fulfilled or rejected.
A promise can be in one of three states: pending, fulfilled, or rejected.
Promises that are fulfilled have a fulfillment value and are in the fulfilled
state. Promises that are rejected have a rejection reason and are in the
rejected state. A fulfillment value is never a thenable.
Promises can also be said to *resolve* a value. If this value is also a
promise, then the original promise's settled state will match the value's
settled state. So a promise that *resolves* a promise that rejects will
itself reject, and a promise that *resolves* a promise that fulfills will
itself fulfill.
Basic Usage:
------------
```js
var promise = new Promise(function(resolve, reject) {
// on success
resolve(value);
// on failure
reject(reason);
});
promise.then(function(value) {
// on fulfillment
}, function(reason) {
// on rejection
});
```
Advanced Usage:
---------------
Promises shine when abstracting away asynchronous interactions such as
`XMLHttpRequest`s.
```js
function getJSON(url) {
return new Promise(function(resolve, reject){
var xhr = new XMLHttpRequest();
xhr.open('GET', url);
xhr.onreadystatechange = handler;
xhr.responseType = 'json';
xhr.setRequestHeader('Accept', 'application/json');
xhr.send();
function handler() {
if (this.readyState === this.DONE) {
if (this.status === 200) {
resolve(this.response);
} else {
reject(new Error("getJSON: `" + url + "` failed with status: [" + this.status + "]"));
}
}
};
});
}
getJSON('/posts.json').then(function(json) {
// on fulfillment
}, function(reason) {
// on rejection
});
```
Unlike callbacks, promises are great composable primitives.
```js
Promise.all([
getJSON('/posts'),
getJSON('/comments')
]).then(function(values){
values[0] // => postsJSON
values[1] // => commentsJSON
return values;
});
```

`RSVP.Promise.all` accepts an array of promises, and returns a new promise which
is fulfilled with an array of fulfillment values for the passed promises, or
rejected with the reason of the first passed promise to be rejected. It casts all
elements of the passed iterable to promises as it runs this algorithm.
Example:
```javascript
var promise1 = RSVP.resolve(1);
var promise2 = RSVP.resolve(2);
var promise3 = RSVP.resolve(3);
var promises = [ promise1, promise2, promise3 ];
RSVP.Promise.all(promises).then(function(array){
// The array here would be [ 1, 2, 3 ];
});
```
If any of the `promises` given to `RSVP.all` are rejected, the first promise
that is rejected will be given as an argument to the returned promises's
rejection handler. For example:
Example:
```javascript
var promise1 = RSVP.resolve(1);
var promise2 = RSVP.reject(new Error("2"));
var promise3 = RSVP.reject(new Error("3"));
var promises = [ promise1, promise2, promise3 ];
RSVP.Promise.all(promises).then(function(array){
// Code here never runs because there are rejected promises!
}, function(error) {
// error.message === "2"
});
```
@method all
@static
@param {Array} entries array of promises
@param {String} label optional string for labeling the promise.
Useful for tooling.
@return {Promise} promise that is fulfilled when all `promises` have been
fulfilled, or rejected if any of them become rejected.

/**
@deprecated
`RSVP.Promise.cast` coerces its argument to a promise, or returns the
argument if it is already a promise which shares a constructor with the caster.
Example:
```javascript
var promise = RSVP.Promise.resolve(1);
var casted = RSVP.Promise.cast(promise);
console.log(promise === casted); // true
```
In the case of a promise whose constructor does not match, it is assimilated.
The resulting promise will fulfill or reject based on the outcome of the
promise being casted.
Example:
```javascript
var thennable = $.getJSON('/api/foo');
var casted = RSVP.Promise.cast(thennable);
console.log(thennable === casted); // false
console.log(casted instanceof RSVP.Promise) // true
casted.then(function(data) {
// data is the value getJSON fulfills with
});
```
In the case of a non-promise, a promise which will fulfill with that value is
returned.
Example:
```javascript
var value = 1; // could be a number, boolean, string, undefined...
var casted = RSVP.Promise.cast(value);
console.log(value === casted); // false
console.log(casted instanceof RSVP.Promise) // true
casted.then(function(val) {
val === value // => true
});
```
`RSVP.Promise.cast` is similar to `RSVP.Promise.resolve`, but `RSVP.Promise.cast` differs in the
following ways:
* `RSVP.Promise.cast` serves as a memory-efficient way of getting a promise, when you
have something that could either be a promise or a value. RSVP.resolve
will have the same effect but will create a new promise wrapper if the
argument is a promise.
* `RSVP.Promise.cast` is a way of casting incoming thenables or promise subclasses to
promises of the exact class specified, so that the resulting object's `then` is
ensured to have the behavior of the constructor you are calling cast on (i.e., RSVP.Promise).
@method cast

@param {Object} object to be casted
@param {String} label optional string for labeling the promise.

`RSVP.Promise.race` returns a new promise which is settled in the same way as the
first passed promise to settle.
Example:
```javascript
var promise1 = new RSVP.Promise(function(resolve, reject){
setTimeout(function(){
resolve("promise 1");
}, 200);
});
var promise2 = new RSVP.Promise(function(resolve, reject){
setTimeout(function(){
resolve("promise 2");
}, 100);
});
RSVP.Promise.race([promise1, promise2]).then(function(result){
// result === "promise 2" because it was resolved before promise1
// was resolved.
});
```
`RSVP.Promise.race` is deterministic in that only the state of the first
settled promise matters. For example, even if other promises given to the
`promises` array argument are resolved, but the first settled promise has
become rejected before the other promises became fulfilled, the returned
promise will become rejected:
```javascript
var promise1 = new RSVP.Promise(function(resolve, reject){
setTimeout(function(){
resolve("promise 1");
}, 200);
});
var promise2 = new RSVP.Promise(function(resolve, reject){
setTimeout(function(){
reject(new Error("promise 2"));
}, 100);
});
RSVP.Promise.race([promise1, promise2]).then(function(result){
// Code here never runs
}, function(reason){
// reason.message === "promise 2" because promise 2 became rejected before
// promise 1 became fulfilled
});
```
An example real-world use case is implementing timeouts:
```javascript
RSVP.Promise.race([ajax('foo.json'), timeout(5000)])

`RSVP.rethrow` will rethrow an error on the next turn of the JavaScript event
loop in order to aid debugging.
Promises A+ specifies that any exceptions that occur with a promise must be
caught by the promises implementation and bubbled to the last handler. For
this reason, it is recommended that you always specify a second rejection
handler function to `then`. However, `RSVP.rethrow` will throw the exception
outside of the promise, so it bubbles up to your console if in the browser,
or domain/cause uncaught exception in Node. `rethrow` will also throw the
error again so the error can be handled by the promise per the spec.
```javascript
function throws(){
throw new Error('Whoops!');
}
var promise = new RSVP.Promise(function(resolve, reject){
throws();
});
promise.catch(RSVP.rethrow).then(function(){
// Code here doesn't run because the promise became rejected due to an
// error!
}, function (err){
// handle the error here
});
```
The 'Whoops' error will be thrown on the next turn of the event loop
and you can watch for it in your console. You can also handle it using a
rejection handler given to `.then` or `.catch` on the returned promise.
