p.66 create an articles new controller

[mfromin]

p.66 of my PDF states this:

Tasks
Create an articles new controller and validate that the model includes description. 
If it is valid, let the action bubble to the route. Otherwise, set an errorMessage.

When I look at the code commits for this portion of the tutorial I would expect to see a file:

app/controllers/articles/new.js

...but I don't see one at all. Am I missing the intent of the task on p 66 of the PDF? When I click the link to look at the changes introduced (262f8c1) there is no articles controller of any type. The final project also does not have a new.js controller for articles.

What I did based on the task is to create the file app/controllers/articles/new.js and put the following code in there:

import Ember from 'ember';

export default Ember.Controller.extend({
    hasDescription: Ember.computed.notEmpty('model.description'),
    isValid: Ember.computed.and(
        'hasDescription'
    ),
    actions: {
        save: function () {
            console.log('+- save action in articles/new controller');
            if (this.get('isValid')) {
                return true;
            } else {
                this.set('errorMessage', 'You have to fill in all the fields');
                return false;
            }
        },
        cancel: function () { 
            return true;
        }
    }
});

I've noticed the same issue. Was throwing me for a loop.
