import Ember from 'ember';
import Utils from 'docket/utils';
import Status from 'docket/models/status';
import User from 'docket/models/user';

export default Ember.Route.extend({

    this._super();
    // do some setup related to event_source here
  },

  beforeModel: function() {
    // if we return a promise this should block until it is resolved
    var store = this.get('store');

    var promises = [
      // where I do Utils.current_user = user; you could do store.push, I believe
      store.find('user', Utils.current_user_id).then(function(user) {Utils.current_user = user;}),
      store.find('status', Status.OPEN_ID).then(function(status) {Status.OPEN = status;}),

    ]

    return Ember.RSVP.all(promises, 'preloading');
  },

  // this sets up the application controller, not necessary
  setupController: function(controller, model) {
    this._super(controller, model);

    controller.set('current_user', Utils.current_user);

    // status for sidebar filtering
    controller.set('status_open_id', Status.OPEN_ID);
    controller.set('status_closed_id', Status.CLOSED_ID);
    controller.set('status_reviewed_id', Status.REVIEWED_ID);
    controller.set('status_invoiced_id', Status.INVOICED_ID);

    // user ids for sidebar filtering
    controller.set('current_user_id', Utils.current_user_id);
    controller.set('user_unclaimed_id', User.UNCLAIMED_ID);
    controller.set('user_all_id', User.ALL_ID);
  }

});

This is in routes/application.es6 for me. I have not updated Ember stuff in some time. YMMV. Hope it helps!
