Define the ember data model for nested rest url

I am trying to do something that sounds simple but I can't find the solution.

My application needs to edit documents which contains pages.

Here is my model :

MyApplication.Document = DS.Model.extend({
    title: DS.attr('string'),
    pages: DS.hasMany('page', {async: true})
});
MyApplication.Page = DS.Model.extend({
    document: DS.belongsTo('document', {async: true}),
    title: DS.attr('string'),
    params: DS.attr(),
    objects: DS.attr()
});

When I load the document 1, the application call http://ift.tt/16LGK09.

The problem is that when I want to find a page of the document, it calls

• http://ift.tt/1zGDGy0

instead of

• http://ift.tt/16LGK0b

Theses nested URL are important in my application.

I found different things on the subject like adding links in the JSON response :

{
    "document": {
        "id": "1",
        "title": "Titre du document",
        "pages": ["1", "2", "3"],
        "links": {"pages" : "pages"}
},

But when I call for the pages, it requests http://ift.tt/1zGDGy5 without the id.

I also try specify the document when I ask for the page :

this.store.find("page", 1, {document:1});

Can't find a complete documentation on this subject, so if someone can explain me what's wrong, I'll be happy.

Thank.
