BEWARE:
You want to be careful about whether or not returning multiple models in your model hook is appropriate. Ask yourself this simple question:
- Does my route load dynamic data based on the url using a slug
:id? i.e.
this.resource('foo', {path: ':id'});
If you answered yes
Do not attempt to load multiple models from the model hook in that route!!! The reason lies in the way Ember handles linking to routes. If you provide a model when linking to that route ({{link-to 'foo' model}}, transitionTo('foo', model)) it will skip the model hook and use the supplied model. This is probably problematic since you expected multiple models, but only one model would be delivered. Here's an alternative:
Do it in setupController/afterModel
App.IndexRoute = Ember.Route.extend({
model: function(params) {
return $.getJSON('/books/' + params.id);
},
setupController: function(controller, model){
this._super(controller,model);
controller.set('model2', {bird:'is the word'});
}
});

If you need it to block the transition (like the model hook does) return a promise from the afterModel hook. You will need to manually keep track of the results from that hook and hook them up to your controller.
App.IndexRoute = Ember.Route.extend({
model: function(params) {
return $.getJSON('/books/' + params.id);
},
afterModel: function(){
var self = this;
return $.getJSON('/authors').then(function(result){
self.set('authors', result);
});
},
setupController: function(controller, model){
this._super(controller,model);
controller.set('authors', this.get('authors'));
}
});

If you answered no
Go ahead, let's return multiple models from the route's model hook:
App.IndexRoute = Ember.Route.extend({
model: function() {
return {
model1: ['red', 'yellow', 'blue'],
model2: ['green', 'purple', 'white']
};
}
});
Example: http://emberjs.jsbin.com/tuvozuwa/1/edit
If it's something that needs to be waited on (such as a call to the server, some sort of promise)
App.IndexRoute = Ember.Route.extend({
model: function() {
return Ember.RSVP.hash({
model1: promise1,
model2: promise2
});
}
});
Example: http://emberjs.jsbin.com/xucepamezu/1/edit
In the case of Ember Data
App.IndexRoute = Ember.Route.extend({
var store = this.store;
model: function() {
return Ember.RSVP.hash({
cats: store.find('cat'),
dogs: store.find('dog')
});
}
});
Example: http://emberjs.jsbin.com/pekohijaku/1/edit
If one is a promise, and the other isn't, it's all good, RSVP will gladly just use that value
App.IndexRoute = Ember.Route.extend({
var store = this.store;
model: function() {
return Ember.RSVP.hash({
cats: store.find('cat'),
dogs: ['pluto', 'mickey']
});
}
});
Example: http://emberjs.jsbin.com/coxexubuwi/1/edit
Mix and match and have fun!
App.IndexRoute = Ember.Route.extend({
var store = this.store;
model: function() {
return Ember.RSVP.hash({
cats: store.find('cat'),
dogs: Ember.RSVP.Promise.cast(['pluto', 'mickey']),
weather: $.getJSON('weather')
});
},
setupController: function(controller, model){
this._super(controller, model);
controller.set('favoritePuppy', model.dogs[0]);
}
});
