Using primary keys with Ember Data

Question

Answer 1

In case the solution suggested by Nikita doesn't work (didn't for me using revision 11 of ember-data), here is how I changed the primary key when working with the RESTAdapter:

App.Adapter = DS.RESTAdapter.extend({
    serializer: "App.MySerializer"
});

// notice we extend the RESTSerializer, not Serializer!
App.MySerializer = DS.RESTSerializer.extend({
    primaryKey: function(type) {
        return '_id'; // you get it...
    }
});
