Ember get hasMany - ember.js

Question

I have Model
EmberApp.Card = DS.Model.extend({
balance: DS.attr('number'),
operations: DS.hasMany('operation', { async: true })
});
Than I make
self.store.find('card', 'me')
response
{
"card": {
"id": "53620486168e3e581cb5851a",
"balance": 20
}
}
getting card Model but without operations and setting it to controller prop "currentCard"
Then I want to find operations throw url /cards/me/operations
response
{"operation": [{ "id": 1, "type": 1 }] }
How can I do it from this.controllerFor('*').get('currentCard')... ?

Answer 1

You actually need to return your operations as a list of ID's in your card response like this:
{
"card": {
"id": "53620486168e3e581cb5851a",
"balance": 20,
"operations": [1, 2, 3]
}
}
This will enable you to do this in another route:
this.modelFor('card').get('operations');
or this in your cards controller:
this.get('content.operations');
This will execute the following call to your API:
/api/operations?ids[]=1&ids[]=2&ids[]=3

First of all you should add links to response from cards/me
EmberApp.ApplicationSerializer = DS.RESTSerializer.extend({
normalizePayload: function(type, payload) {
if (type.toString() === 'EmberApp.Card') {
payload.links = { 'operations': '/cards/me/operations' };
return { card: payload };
} else if (type.toString() === 'EmberApp.Operation') {
return { operations: payload };
}
}
});
Then in route
EmberApp.CardOperationsRoute = Ember.Route.extend({
model: function() {
return this.controllerFor('sessions.new')
.get('currentCard')
.get('operations');
}
});
