Cannot use Ember associations

I have been trying to make this work for several days now. I cannot access a profile object from its associated user object. I have the latest versions of Ember and ember-data

Ember-data: 1.0.0-beta15
Ember: 1.10.0 production

I have a simple table view that lists my users and a couple properties.

The models are like so:

App.Profile = DS.Model.extend({
        user: DS.belongsTo('user'),
        incognito_name : DS.attr('string'),
        advisor_id : DS.attr('number'),
        created_at : DS.attr('date'),
        //etc..

App.User = DS.Model.extend({
    profile: DS.belongsTo('profile',{ async: true }),
    email: DS.attr('string'),
    sign_in_count: DS.attr('number'),
    last_sign_in_at: DS.attr('date'),
    //etc...

I am using the rest adapter:

App.ApplicationAdapter = DS.RESTAdapter.extend({
  host: 'http://localhost:1337',
  defaultSerializer: 'json'
});

My server is a SailsJS back end, which accesses a database created by a Rails application.

I want to alter the profile in this object controller, but cannot access it in any meaningful form:

App.CandidateController = Ember.ObjectController.extend({
  actions: {
      markVerified: function(){
          var user = this.get('model');
          var profile = user.get('profile');
          console.log(profile);  //output 1
          console.log(profile.incognito_name); //output 2
    }
  }
});

The output2 is undefined. Output 1 gives me some sort of object with properties __nextSuper, __ember_meta, a bunch of other things, isFulfilled, and content. But, no object properties from the model definition. This appears to be a promisearray,but, I thought this was the way to get a related object. Meanwhile, when I try to treat it as a PromiseArray, per the documentation, i get null, like this:

App.CandidateController = Ember.ObjectController.extend({
  actions: {
      markVerified: function(){
          var user = this.get('model');
          user.get('profile').then(function(content){
              console.log("promise content is " + content);
              //prints 'promise content is null'
          })
          //console.log(profile);
          //console.log(profile.incognito_name);

    }
  }

I am fairly certain all my back end server/client things are in order, as I can access the user objects and work with them on the page. I am thinking it may be related to how the profile relates to the user via advisor_id, but, I am so confused right now. I am very much at my wit's end.
