Ember Data returning a structured JSON - ember.js

Question

I've been working with Ember Data for a while now and I'm mostly happy with it. I like the way that it has forced me to structure my REST api in a sensible way.
I'm coming into a few problems tho, here's one of them: I was using a model with a flat structure before:
App.Pageview = DS.Model.extend({
event: attr('string'),
value: attr('string'),
time: attr('date'),
count: attr('number')
});
In this case value was a url all in one string. This model would work fine with JSON that would look like this:
{
"event" : "pageview",
"value" : "google.com/some/page",
"time" : "2013-01-31T16:30:00.000Z",
"count" : 14
}
I've changed the way the JSON is structured in the database to make it easier to query so now it looks like this:
{
"event" : "pageview",
"value" : {
"url" : "google.com/some/page",
"domain" : "google.com",
"path" : "/some/page"
},
"time" : "2013-01-31T16:30:00.000Z",
"count" : 14
}
But now i don't really know where to go with things. I tried doing things like this:
App.Pageview = DS.Model.extend({
event: attr('string'),
value: {
domain: attr('string'),
url: attr('string'),
path: attr('string')
},
time: attr('date'),
count: attr('number')
});
But that didn't seem to work, I tested it like this:
console.log(item.get('value'));
console.log(item.get('value.domain'));
// console.log(item.get('value').get('domain')); // throws
console.log(item.get('value').domain);
And got the following results: http://d.pr/i/izDD
So I did some more digging and found that i should probably do something like this:
App.Pageview = DS.Model.extend({
event: attr('string'),
value: DS.belongsTo('App.SplitUrl', {embedded:true}),
time: attr('date'),
count: attr('number')
});
App.SplitUrl = DS.Model.extend({
domain: attr('string'),
url: attr('string'),
path: attr('string')
});
But this doesn't work because of an error i get:
Uncaught TypeError: Cannot call method 'hasOwnProperty' of undefined
This usually happens when I have sent an object down my REST api without an id. Here is the exact response from my REST api:
http://d.pr/n/UyW0
Note: i've overloaded the Adapter so that it expects the id to be in the _id field so that it can work better/easier with mongodb. This is how I have overloaded the Adapter:
App.Store = DS.Store.extend({
revision: 11,
adapter: DS.RESTAdapter.create({
serializer: DS.JSONSerializer.extend({
primaryKey: function(type) {
return '_id';
}
}),
namespace: 'api'
})
});
Can anyone help me figure this one out?

Assuming you're using ember-data revision 11, try to configure your value as embedded in the adapter instead.
DS.RESTAdapter.map('App.SplitUrl',{value:{ embedded:'always'}});
