Ember-data JSON structure - ember.js

Question

I have 5 models in some relations:
App.Service = DS.Model.extend({
name: DS.attr('string'),
service_prices: DS.hasMany('servicePrice')
});
App.ServicePrice = DS.Model.extend({
unit_price: DS.attr('number'),
qty_unit: DS.belongsTo('qtyUnit'),
service: DS.belongsTo('service'),
partner:DS.belongsTo('partner')
});
App.Partner = DS.Model.extend({
"name": DS.attr('string')
});
App.QtyUnit = DS.Model.extend(Ember.Validations.Mixin, {
name: DS.attr('string'),
});
App.Order = DS.Model.extend({
service: DS.belongsTo('service'),
unit_price: DS.attr('numeric'),
qty_unit:DS.belongsTo('qtyUnit')
});
I try to load an order with the following JSON:
var order = {
"order" : {"id":1,"service":1,"qty_unit":4,"unit_price":10},
"service":[{"id":1,"name":"ENG-GER","service_prices":[1,2]}],
"servicePrices":[
{"id":1,"qty_unit":4,"unit_price":3,"partner":1},
{"id":2,"qty_unit":5,"unit_price":4,"partner":1}
],
"qtyUnits":[
{"id":4,"name":"character"},
{"id":5,"name":"word"},
{"id":6,"name":"sentence"}
],
"partner":[
{"id":1,"name":"Jessie Bains"}
]
};
But im getting the following error:
Error while loading route: TypeError: Cannot read property 'deserialize' of undefined
Is my Json wrong structured?
Here is the JsBin:

When requesting records, the relationships in the json should be plural (services, partners)
var order = {
"order" : {"id":1,"service":1,"qty_unit":4,"unit_price":10},
"services":[{"id":1,"name":"ENG-GER","service_prices":[1,2]}],
"servicePrices":[
{"id":1,"qty_unit":4,"unit_price":3,"partner":1},
{"id":2,"qty_unit":5,"unit_price":4,"partner":1}
],
"qtyUnits":[
{"id":4,"name":"character"},
{"id":5,"name":"word"}
],
"partners":[
{"id":1,"name":"Jessie Bains"}
]
};
Additionally your jsbin isn't working per say because:
services and qtyUnits didn't exist in the scope (possibly you debugging)
return Ember.RSVP.hash({
order:store.find('order',1),
services: store.all('service'),
qtyUnits: store.all('qtyUnit')
});
If your controller has an object backing it is needs to extend ObjectController not Controller
App.IndexController = Ember.ObjectController.extend({
});
