Module: ember-routing
The Ember.Route class is used to define individual routes. Refer to the routing guide for documentation.
Populates the QP meta information in the BucketCache.
Sets the name for this route, including a fully resolved name for routes inside engines.
String
This hook is executed when the router enters the route. It is not executed when the model for the route changes.
Promisepublic
This hook is called after this route's model has resolved. It follows identical async/promise semantics to beforeModel but is provided the route's resolved model in addition to the transition, and is therefore suited to performing logic that can only take place after the model has already resolved.
app/routes/posts.jsimport Ember from 'ember';
export default Ember.Route.extend({
afterModel(posts, transition) {
if (posts.get('length') === 1) {
this.transitionTo('post.show', posts.get('firstObject'));
}
}
});
Refer to documentation for beforeModel for a description of transition-pausing semantics when a promise is returned from this hook.

Promise Promisepublic
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.
Transition
Promise Called when the context is changed by router.js.
Ember.Controllerpublic
Returns the resolved model of the current route, or a parent (or any ancestor) route in a route hierarchy.
The controller instance must already have been created, either through entering the associated route or using generateController.
app/routes/post.jsimport Ember from 'ember';
export default Ember.Route.extend({
setupController(controller, post) {
this._super(controller, post);
this.controllerFor('posts').set('currentPost', post);
}
});
String
This hook is executed when the router completely exits this route. It is not executed when the model for the route changes.

Disconnects a view that has been rendered into an outlet.
You may pass any or all of the following options to disconnectOutlet:
outlet: the name of the outlet to clear (default: 'main')parentView: the name of the view containing the outlet to clear (default: the view rendered by the parent route)Example:
app/routes/application.jsimport Ember from 'ember';
export default App.Route.extend({
actions: {
showModal(evt) {
this.render(evt.modalName, {
outlet: 'modal',
into: 'application'
});
},
hideModal(evt) {
this.disconnectOutlet({
outlet: 'modal',
parentView: 'application'
});
}
}
});
Alternatively, you can pass the outlet name directly as a string.
Example:
app/routes/application.jsimport Ember from 'ember';
export default App.Route.extend({
actions: {
showModal(evt) {
// ...
},
hideModal(evt) {
this.disconnectOutlet('modal');
}

this.generateController('posts');
}
});
String
Perform a synchronous transition into another route without attempting to resolve promises, update the URL, or abort any currently active asynchronous transitions (i.e. regular transitions caused by transitionTo or URL changes).
This method is handy for performing intermediate transitions on the way to a final destination route, and is called internally by the default implementations of the error and loading handlers.

A hook you can implement to convert the URL into the model for this route.
app/router.js// ...
Router.map(function() {
this.route('post', { path: '/posts/:post_id' });
});
export default Router;
The model for the post route is store.findRecord('post', params.post_id).
By default, if your route has a dynamic segment ending in _id:
post_id's class is App.Post)Note that for routes with dynamic segments, this hook is not always executed. If the route is entered through a transition (e.g. when using the link-to Handlebars helper or the transitionTo method of routes), and a model context is already provided this hook is not called.
A model context does not include a primitive string or number, which does cause the model hook to be called.
Routes without dynamic segments will always execute the model hook.
// no dynamic segment, model hook always called
this.transitionTo('posts');
// model passed in, so model hook not called
thePost = store.findRecord('post', 1);
this.transitionTo('post', thePost);
// integer passed in, model hook is called
this.transitionTo('post', 1);
// model id passed in, model hook is called
// useful for forcing the hook to execute
thePost = store.findRecord('post', 1);
this.transitionTo('post', thePost.id);
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
app/routes/post.jsimport Ember from 'ember';
export default Ember.Route.extend({
model(params) {
return this.store.findRecord('post', params.post_id);
}
});

Transition

Returns the resolved model of a parent (or any ancestor) route in a route hierarchy. During a transition, all routes must resolve a model object, and if a route needs access to a parent route's model in order to resolve a model (or just reuse the model from a parent), it can call this.modelFor(theNameOfParentRoute) to retrieve it. If the ancestor route's model was a promise, its resolved result is returned.
Example
app/router.js// ...
Router.map(function() {
this.route('post', { path: '/posts/:post_id' }, function() {
this.route('comments');
});
});
export default Router;
app/routes/comments.jsimport Ember from 'ember';

let post = this.modelFor('post');
return post.get('comments');

this.route('member', { path: ':name' }, function() {
this.route('interest', { path: ':interest' });
});
});
app/routes/member.jsexport default Ember.Route.extend({
queryParams: {
memberQp: { refreshModel: true }

});
app/routes/member/interest.jsexport default Ember.Route.extend({
queryParams: {
interestQp: { refreshModel: true }
},
model() {
return this.paramsFor('member');

});
If we visit /turing/maths?memberQp=member&interestQp=interest the model for the member.interest route is hash with:
name: turing
memberQp: member

Object
Boolean A hook you can implement to optionally redirect to another route.
If you call this.transitionTo from inside of this hook, this route will not be entered in favor of the other hook.
redirect and afterModel behave very similarly and are called almost at the same time, but they have an important 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, both the resolved model and attempted entry into this route are considered to be fully validated.
Object
Transition
Transitionpublic
Refresh the model on this route and any child routes, firing the beforeModel, model, and afterModel hooks in a similar fashion to how routes are entered when transitioning in from other route. The current route params (e.g. article_id) will be passed in to the respective model hooks, and if a different model is returned, setupController and associated route hooks will re-fire as well.
An example usage of this method is re-querying the server for the latest information using the same parameters as when the route was first entered.
Note that this will cause model hooks to fire even on routes that were provided a model object when the route was initially entered.
Transition render is used to render a template into a region of another template (indicated by an {{outlet}}). render is used both during the entry phase of routing (via the renderTemplate hook) and later in response to user interaction.
For example, given the following minimal router and templates:
app/router.js// ...
Router.map(function() {
this.route('photos');
});
export default Router;
<!-- application.hbs -->
<div class='something-in-the-app-hbs'>
{{outlet "anOutletName"}}
</div>
<!-- photos.hbs --> <h1>Photos</h1>
You can render photos.hbs into the "anOutletName" outlet of application.hbs by calling render:
app/routes/post.jsimport Ember from 'ember';
export default Ember.Route.extend({
renderTemplate() {
this.render('photos', {
into: 'application',
outlet: 'anOutletName'
})
}
});
render additionally allows you to supply which controller and model objects should be loaded and associated with the rendered template.
app/routes/posts.jsimport Ember from 'ember';
export default Ember.Route.extend({
renderTemplate(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.
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, 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. The template to render into needs to be related to either the current route or one of its ancestors.
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 and templateName properties.
For example:
app/router.js// ...
Router.map(function() {
this.route('index');
this.route('post', { path: '/posts/:post_id' });
});
export default Router;
app/routes/post.jsimport Ember from 'ember';
export default Ember.Route.extend({
renderTemplate() {
this.render(); // all defaults apply
}
});
The name of the route, defined by the router, is post.
The following equivalent default options will be applied when the Route calls render:
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,
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.

A hook you can use to render the template 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, it renders the route's template, configured with the controller for the route.
This method can be overridden to set up and render additional or alternative templates.
app/routes/posts.jsimport Ember from 'ember';
export default Ember.Route.extend({
renderTemplate(controller, model) {
let favController = this.controllerFor('favoritePost');
// Render the `favoritePost` template into
// the outlet `posts`, and display the `favoritePost`
// controller.
this.render('favoritePost', {
outlet: 'posts',
controller: favController
});
}
});

Transitionpublic
Transition into another route while replacing the current URL, if possible. This will replace the current history entry instead of adding a new one. Beside that, it is identical to transitionTo in all other respects. See 'transitionTo' for additional information regarding multiple models.
Example
app/router.js// ...
Router.map(function() {
this.route('index');
this.route('secret');
});
export default Router;
app/routes/secret.jsimport Ember from 'ember';
export default Ember.Route.extend({
afterModel() {

this.replaceWith('index');
}
}
});

Transition A hook you can use to reset controller values either when the model changes or the route is exiting.
app/routes/articles.jsimport Ember from 'ember';

if (isExiting) {
controller.set('page', 1);
}
}
});

Sends an action to the router, which will delegate it to the currently active route hierarchy per the bubbling rules explained under actions.
Example
app/router.js// ...
Router.map(function() {
this.route('index');
});
export default Router;
app/routes/application.jsimport Ember from 'ember';
export default Ember.Route.extend({
actions: {
track(arg) {
console.log(arg, 'was clicked');
}
}
});
app/routes/index.jsimport Ember from 'ember';
export default Ember.Route.extend({
actions: {
trackIfDebug(arg) {
if (debug) {
this.send('track', arg);
}
}
}
});

A hook you can implement to convert the route's model into parameters for the URL.
app/router.js// ...
Router.map(function() {
this.route('post', { path: '/posts/:post_id' });
});
app/routes/post.jsimport Ember from 'ember';
export default Ember.Route.extend({
model(params) {
// the server returns `{ id: 12 }`
return Ember.$.getJSON('/posts/' + params.post_id);
},
serialize(model) {
// this will make the URL `/posts/12`
return { post_id: model.id };
}
});
The default serialize method will insert the model's id into the route's dynamic segment (in this case, :post_id) if the segment contains 'id'. If the route has multiple dynamic segments or does not contain 'id', serialize will return Ember.getProperties(model, params)
This method is called when transitionTo is called with a context in order to populate the URL.

This hook is the entry point for router.js
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:
app/routes/photos.jsimport Ember from 'ember';
export default Ember.Route.extend({
model() {
return this.store.findAll('photo');
},
setupController(controller, model) {
// Call _super for default behavior
this._super(controller, model);
// Implement your custom setup after
this.controllerFor('application').set('showingPhotos', true);
}
});
The provided controller will be one resolved based on the name of this route.
If no explicit controller is defined, Ember will automatically create one.
As an example, consider the router:
app/router.js// ...
Router.map(function() {
this.route('post', { path: '/posts/:post_id' });
});
export default Router;
For the post route, a controller named App.PostController would be used if it is defined. If it is not defined, a basic Ember.Controller instance would be used.
Example
app/routes/post.jsimport Ember from 'ember';
export default Ember.Route.extend({
setupController(controller, model) {
controller.set('model', model);
}
});
Controller

Store property provides a hook for data persistence libraries to inject themselves.
By default, this store property provides the exact same functionality previously in the model hook.
Currently, the required interface is:
store.find(modelName, findArguments)
Object
Transitionpublic
Transition the application into another route. The route may be either a single route or route path:
this.transitionTo('blogPosts');
this.transitionTo('blogPosts.recentEntries');
Optionally supply a model for the route in question. The model will be serialized into the URL using the serialize hook of the route:
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:
this.transitionTo('blogPost', 1);
Multiple models will be applied last to first recursively up the route tree.
app/routes.js// ...
Router.map(function() {
this.route('blogPost', { path:':blogPostId' }, function() {
this.route('blogComment', { path: ':blogCommentId' });
});
});
export default Router;
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.
this.transitionTo('/');
this.transitionTo('/blog/post/1/comment/13');
this.transitionTo('/blog/posts?sort=title');
An options hash with a queryParams property may be provided as the final argument to add query parameters to the destination URL.
this.transitionTo('blogPost', 1, {
queryParams: { showComments: 'true' }
});
// if you just want to transition the query parameters without changing the route
this.transitionTo({ queryParams: { sort: 'date' } });
See also replaceWith.
Simple Transition Example
app/routes.js// ...
Router.map(function() {
this.route('index');
this.route('secret');
this.route('fourOhFour', { path: '*:' });
});
export default Router;
app/routes/index.jsimport Ember from 'ember':
export Ember.Route.extend({
actions: {
moveToSecret(context) {
if (authorized()) {
this.transitionTo('secret', context);
} else {
this.transitionTo('fourOhFour');
}
}
}
});
Transition to a nested route
app/router.js// ...
Router.map(function() {
this.route('articles', { path: '/articles' }, function() {
this.route('new');
});
});
export default Router;
app/routes/index.jsimport Ember from 'ember';
export default Ember.Route.extend({
actions: {
transitionToNewArticle() {
this.transitionTo('articles.new');
}
}
});
Multiple Models Example
app/router.js// ...
Router.map(function() {
this.route('index');
this.route('breakfast', { path: ':breakfastId' }, function() {
this.route('cereal', { path: ':cerealId' });
});
});
export default Router;
app/routes/index.jsimport Ember from 'ember';
export default Ember.Route.extend({
actions: {
moveToChocolateCereal() {
let cereal = { cerealId: 'ChocolateYumminess' };
let breakfast = { breakfastId: 'CerealAndMilk' };
this.transitionTo('breakfast.cereal', breakfast, cereal);
}
}
});
Nested Route with Query String Example
app/routes.js// ...
Router.map(function() {
this.route('fruits', function() {
this.route('apples');
});
});
export default Router;
app/routes/index.jsimport Ember from 'ember';
export default Ember.Route.extend({
actions: {
transitionToApples() {
this.transitionTo('fruits.apples', { queryParams: { color: 'red' } });
}
}
});

Transition This event is triggered when the router enters the route. It is not executed when the model for the route changes.
app/routes/application.jsimport Ember from 'ember';
export default Ember.Route.extend({
collectAnalytics: Ember.on('activate', function(){
collectAnalytics();
})
});
This event is triggered when the router completely exits this route. It is not executed when the model for the route changes.
app/routes/index.jsimport Ember from 'ember';
export default Ember.Route.extend({
trackPageLeaveAnalytics: Ember.on('deactivate', function(){
trackPageLeaveAnalytics();
})
});
The didTransition action is fired after a transition has successfully been completed. This occurs after the normal model hooks (beforeModel, model, afterModel, setupController) have resolved. The didTransition action has no arguments, however, it can be useful for tracking page views or resetting state on the controller.
app/routes/login.jsimport Ember from 'ember';
export default Ember.Route.extend({
actions: {
didTransition() {
this.controller.get('errors.base').clear();
return true; // Bubble the didTransition event
}
}
});
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:
app/routes/admin.jsimport Ember from 'ember';
export default Ember.Route.extend({
beforeModel() {
return Ember.RSVP.reject('bad things!');
},
actions: {
error(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:
app/routes/application.jsimport Ember from 'ember';
export default Ember.Route.extend({
actions: {
error(error, transition) {
this.controllerFor('banner').displayError(error.message);
}
}
});
Error
Transition
The loading action is fired on the route when a route's model hook returns a promise that is not already resolved. The current Transition object is the first parameter and the route that triggered the loading event is the second parameter.
app/routes/application.jsexport default Ember.Route.extend({
actions: {
loading(transition, route) {
let controller = this.controllerFor('foo');
controller.set('currentlyLoading', true);
transition.finally(function() {
controller.set('currentlyLoading', false);
});
}
}
});
Transition
Ember.Route
The willTransition action is fired at the beginning of any attempted transition with a Transition object as the sole argument. This action can be used for aborting, redirecting, or decorating the transition from the currently active routes.
A good example is preventing navigation when a form is half-filled out:
app/routes/contact-form.jsimport Ember from 'ember';
export default Ember.Route.extend({
actions: {
willTransition(transition) {
if (this.controller.get('userHasEnteredData')) {
this.controller.displayNavigationConfirm();
transition.abort();
}
}
}
});
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().
To allow the willTransition event to continue bubbling to the parent route, use return true;. When the willTransition method has a return value of true then the parent route's willTransition method will be fired, enabling "bubbling" behavior for the event.
Transition
Ember.Controllerpublic
The controller associated with this route.
Example
app/routes/form.jsimport Ember from 'ember';
export default Ember.Route.extend({
actions: {
willTransition(transition) {
if (this.controller.get('userHasEnteredData') &&
!confirm('Are you sure you want to abandon progress?')) {
transition.abort();
} else {
// Bubble the `willTransition` action so that
// parent routes can decide whether or not to abort.
return true;
}
}
}
});
Stringpublic
The name of the controller to associate with this route.
By default, Ember will lookup a route's controller that matches the name of the route (i.e. App.PostController for App.PostRoute). However, if you would like to define a specific controller to use, you can do so using this property.
This is useful in many ways, as the controller specified will be:
setupController method.controllerFor for the route. Default: null
Objectpublic
Configuration hash for this route's queryParams. The possible configuration options and their defaults are as follows (assuming a query param whose controller property is page):
queryParams: {
page: {
// By default, controller query param properties don't
// cause a full transition when they are changed, but
// rather only cause the URL to update. Setting
// `refreshModel` to true will cause an "in-place"
// transition to occur, whereby the model hooks for
// this route (and any child routes) will re-fire, allowing
// you to reload models (e.g., from the server) using the
// updated query param values.
refreshModel: false,
// By default, changes to controller query param properties
// cause the URL to update via `pushState`, which means an
// item will be added to the browser's history, allowing
// you to use the back button to restore the app to the
// previous state before the query param property was changed.
// Setting `replace` to true will use `replaceState` (or its
// hash location equivalent), which causes no browser history
// item to be added. This options name and default value are
// the same as the `link-to` helper's `replace` option.
replace: false,
// By default, the query param URL key is the same name as
// the controller property name. Use `as` to specify a
// different URL key.
as: 'page'
}
}
Stringpublic
The name of the route, dot-delimited.
For example, a route found at app/routes/posts/post.js will have a routeName of posts.post.
Stringpublic
The name of the template to use by default when rendering this routes template.
app/routes/posts/list.jsimport Ember from 'ember';
