ember.js sideloaded models not working - ember.js

Question

I'm having to override a route to do some custom loading of models like this:
App.EventsIndexRoute = Ember.Route.extend
model: (params) ->
origin = LJ.origin().join(',')
location = [LJ.stripQuery(params.loc2), params.loc1].join(',')
h = $.param(origin: origin, location: location)
$.getJSON "#{LJ.CONFIG.api.url}/events?#{h}"
The JSON returned includes sideloaded models, but they aren't being loaded by ember. I'm guessing I need to do something to get them loaded but I don't know what. I'd appreciate any help on this.
Here's an example of the returned JSON.
Update
Here's the model definition:
App.Event = DS.Model.extend
acts: DS.hasMany('App.Act')
ageLimit: DS.attr('string')
centsAdvance: DS.attr('number')
centsDoor: DS.attr('number')
currency: DS.attr('string')
description: DS.attr('string')
endsAt: DS.attr('number')
priceAdvance: DS.attr('string')
priceDoor: DS.attr('string')
repeats: DS.attr('string')
repeatsUntil: DS.attr('string')
startsAt: DS.attr('number')
title: DS.attr('string')
url: DS.attr('string')
venue: DS.belongsTo('App.Venue')
venueSection: DS.attr('string')

Answer 1

IMO this has nothing to do with your route but with your model. Make sure that you declare it like that (they have to be present of course)
App.Event = DS.Model.extend({
venue: DS.belongsTo('App.Venue'),
acts: DS.hasMany('App.Act'),
// go on with the model
});
I found it helpful to include a {{ log event }} into the template to dig into the controller and the model and make sure it really does not get loaded
P.s: You do return the ajax response in the route, do you not?

Answer 2

The link of the example JSON you are returning doesn't work, could you please provide a working sample?
You are going around Ember-data for your ajax call, which would mean you will need to handle deserializing it in a more manual manner. If you want ember to do that for you, you need to call into the store, like:
App.EventsRoute = Ember.Route.extend({
model: function() {
// other code here if necessary
return this.store.find('event', params._id);
}
Also, whenever I am not getting my related objects (venues in your case) loaded into the store, it is because the JSON isn't in the format Ember is expecting, which would look like this:
{
Events: [{ Id: 1, Venues: [1], ... }],
Venues: [{ Id: 1, ... }]
}
NOT LIKE THIS:
{
Events: [{ Id: 1, Venue: { Id: 1, ... }, ... }],
}
Maybe this helps?
