Redirecting Edit Page
Before the model is known
If you want to redirect from one route to another, you can do the transition in
the beforeModel
hook of your route handler.

App.Router.map(function() { this.resource('posts'); }); App.IndexRoute = Ember.Route.extend({ beforeModel: function() { this.transitionTo('posts'); } }); |
After the model is known
If you need some information about the current model in order to decide about
the redirection, you should either use the afterModel
or the redirect
hook. They
receive the resolved model as the first parameter and the transition as the second one,
and thus function as aliases. (In fact, the default implementation of afterModel
just calls redirect
.)

App.Router.map(function() { this.resource('posts'); this.resource('post', { path: '/post/:post_id' }); }); App.PostsRoute = Ember.Route.extend({ afterModel: function(posts, transition) { if (posts.length === 1) { this.transitionTo('post', posts[0]); } } }); |
When transitioning to the PostsRoute
it turns out that there is only one post,
the current transition is aborted in favor of redirecting to the PostRoute
with the single post object being its model.
Based on other application state
You can conditionally transition based on some other application state.

App.Router.map(function() { this.resource('topCharts', function() { this.route('choose', { path: '/' }); this.route('albums'); this.route('songs'); this.route('artists'); this.route('playlists'); }); }); App.TopChartsChooseRoute = Ember.Route.extend({ beforeModel: function() { var lastFilter = this.controllerFor('application').get('lastFilter'); this.transitionTo('topCharts.' + lastFilter || 'songs'); } }); // Superclass to be used by all of the filter routes below App.FilterRoute = Ember.Route.extend({ activate: function() { var controller = this.controllerFor('application'); controller.set('lastFilter', this.templateName); } }); App.TopChartsSongsRoute = App.FilterRoute.extend(); App.TopChartsAlbumsRoute = App.FilterRoute.extend(); App.TopChartsArtistsRoute = App.FilterRoute.extend(); App.TopChartsPlaylistsRoute = App.FilterRoute.extend(); |
In this example, navigating to the /
URL immediately transitions into
the last filter URL that the user was at. The first time, it transitions
to the /songs
URL.
Your route can also choose to transition only in some cases. If the
beforeModel
hook does not abort or transition to a new route, the remaining
hooks (model
, afterModel
, setupController
, renderTemplate
) will execute
as usual.
