Initializing and passing an ember.js model/object?

 export default Ember.Route.extend({
   model: function() {
     return this.store.all('foo');
   }
 });

I want to use store.all instead of store.find, correct, since I don't want to load the contents from HTTP?

Then: models/foo

 export default DS.Model.extend({
   firstName: DS.attr('string'),
   lastName: DS.attr('string')
 });

Or should I not be using a model, and an Ember Object instead? The docs for initializing an object say to use App.Foo.Create(), but AFAIK ES6 modules have gotten rid of the App namespace?

Ultimately I want to define a model, then pass that to a component and edit the values. After which I'll save each instance instance of that created model until I need to do something with them.
