emberjs handle 401 not authorized

Question

I am building an ember.js application and am hung up on authentication. The json rest backend is rails. Every request is authenticated using a session cookie (warden).

As of the current version of Ember Data (1.0 beta) you can override the ajaxError method of DS.RESTAdapter:

App.ApplicationAdapter = DS.RESTAdapter.extend({
  ajaxError: function(jqXHR) {
    var error = this._super(jqXHR);
    if (jqXHR && jqXHR.status === 401) {
      #handle the 401 error
    }
    return error;
  }
});

Note that you should call @_super, especially if you are overriding one of the more complex adapters like DS.ActiveModelAdapter, which handles 422 Unprocessable Entity.
