Tell ember.js to use different key for its model's “id”

Question

I am stuck in a situation where I shouldn\'t return id field in the API endpoint. I need to tell ember to use slug field for / instead of id

Answer 1

You need to specify the attribute that should be used as the primaryKey in your Adapter. If you want the slug property to serve as your Post model id, define the primaryKey on your Adapter like this:

DS.RESTAdapter.map('App.Post', {
  primaryKey: 'slug'
});

Update

As of Ember-data version 1.0.0-beta.7 canary, you need to do this instead of the above snippet:

App.PostSerializer = DS.JSONSerializer.extend({
  primaryKey: 'slug'
});
