Updating Ember Relationship Example

gistfile1.js

// When I have a route that provides a model through a relationship...

// app/routes/organization/buyer/loads.js
export default Ember.Route.extend(AuthenticatedRouteMixin, {
  model: function() {
    return this.modelFor('organization/buyer').get('loads');
  }
});

// And I receive new records via the server (via push or poll),
// what is the right way to add those records in a way that
// keeps the model in sync.

// I see that if I call createRecord on the model, that "works".
// $E is set to the instance of the organization/buyer/loads controller.

$E.get('model').createRecord({id: '1234'})

// For testing, I can add a method to push a new record into the store
// every few seconds using the format that server would return.

// app/routes/organization/buyer/loads.js
export default Ember.Route.extend(AuthenticatedRouteMixin, {
  model: function() {
    return this.modelFor('organization/buyer').get('loads');
  },

  startPushing: function() {
    this.push();
  }.on('init'),

  push: function() {
    if (this.currentModel) {
      var id = (this.currentModel.length + 1).toString();
      this.store.pushPayload({"data":{"id": id,"type":"loads","links":{"self":"http://localhost:5000/v1/loads/" + id,"buyer":{"self":"http://localhost:5000/v1/loads/" + id + "/links/buyer","related":"http://localhost:5000/v1/loads/" + id + "/buyer","linkage":{"type":"buyers","id":"1"}}}}})
    }
    Ember.run.later(this, 'push', 3000);
  }
});

// And that works fine! Is `pushPayload` the idiomatic way to do this?

If using store.find of some sort you shouldn't need this. However, if you're using web sockets, polling, or straight jQuery, then you're right on track.
