Configuring ember-data for embedded app

Trying to use Ember and Ember-Data for an Ember app which is embedded in an existing site at URL:

(my-site)/patients

I have a REST/JSON endpoint at:

(my-site)/smart/patients

which returns json as directed by the Ember guide:

{"patients":[{"id":1,"user_id":6,....] }

My js looks like this:

App = Ember.Application.create({
        rootElement: '#patient-data',
        LOG_TRANSITIONS: true,
        LOG_TRANSITIONS_INTERNAL: true,
        LOG_ACTIVE_GENERATION: true
    });

App.Router.map(function() {
    this.resource('patients');
});

App.PatientsRoute = Ember.Route.extend({
      model: function() {
            return this.store.find('patient');
            }
    });

App.Store = DS.Store.extend({
    url: 'http://(my-site)/smart'
});

App.Patient = DS.Model.extend({
    userId: DS.attr('number'),
    etc...
});

App.PatientView = Ember.View.extend({
    didInsertElement: function() {
         do stuff...
        });
    }
});

I am able to get this working by using (with root element [patients] removed from JSON response):

    App.PatientsRoute = Ember.Route.extend({
        model: function() {
            return Ember.$.getJSON('http:(my-site)/smart/patients');
            }
    });

But, I can't get the RESTAdapter to do anything in the PatientsRoute...

I feel like I've tried every permutation of rootURL (App.Router), url (DS.Store) etc and can't get this to function...what am I missing?
