What is the right approach to reload the model for a non-dynamic route with ember.js?

Question

I'm having a simple array of models which I display in a list (path: /things). The models get loaded from a REST-API.

In a nested route I have the functionality to add a new model. (path: /things/add). The new model is persisted over a REST-API.

After adding the new model, I do a transitionTo('things') to get back to the list.

Following the ember documentation, by using "transitionTo" neither the model hook nor the setupController-Hook are called for non dynamic routes.

What is the right approach to refresh the model on a non-dynamic route, when using transitionTo? Or: what is the best way to reload a model on a non-dynamic route without using transitionTo?

app.js

// App Init
App = Ember.Application.create();

// Routes
App.Router.map(function() {
    this.resource('things', function() {
        this.route('add');
    })
});

App.IndexRoute = Ember.Route.extend({
    redirect : function() {
        this.transitionTo('things');
    }
});

App.ThingsRoute = Ember.Route.extend({
    model : function(param) {
        return App.Thing.findAll();
    },
});

App.ThingsAddRoute = Em.Route.extend({
    setupController : function(controller) {
        controller.set('content', App.Thing.create());
    }
});

// Models
App.Thing = Ember.Object.extend({
    name : null,
    description : null
});

App.Thing.reopenClass({
    findAll : function() {
        var result;
        $.ajax({
            url : 'http://path/app_dev.php/api/things',
            dataType : 'json',
            async : false,
            success : function(data) {
                result = data.things;
            }
        });
        return result;
    },
    save : function(content) {
        console.log(content);
        $.ajax({
            type : 'post',
            url : 'http://path/app_dev.php/api/things',
            data : {
                name : content.name,
                description : content.description
            },
            async : false
        });
    }
});

// Controller
App.ThingsAddController = Em.ObjectController.extend({
    add : function() {
        App.Thing.save(this.content);
        this.transitionToRoute('things');
    },
    cancelAdding : function() {
        this.transitionToRoute('things');
    }
});

Answer 1

So if you were using ember-data, a side effect of saving the record would be that the results of findAll() get updated. You can accomplish the same by either manually updating the array or triggering a refresh when a new record is added. In either case, suggest doing that from ThingsAddController's add fx. For example:

App.ThingsAddController = Em.ObjectController.extend({
  needs: [things],
  add : function() {
    newThing = App.Thing.save(this.content);
    this.get('controllers.things').pushObject(newThing);
    this.transitionToRoute('things');
  },
});
