Step 2 - Contact Model

1. Add app.js file with main namespace

   window.ContactManager = {
   Models: {},
   Collections: {},
   Views: {}
   };
   

2. Add models/contact.js with empty model:

   ContactManager.Models.Contact = Backbone.Model.extend({
   });
   

   and to index.html:

   <script src="app/js/models/contact.js"></script>
   

3. Show initialization, accessors, toJSON in console

4. Add defaults to contact model:

   defaults: {
     name: null,
     tel: null,
     email: null,
     avatar: null
   }
   

5. Add random avatar generation:

   initialize: function() {
     this.set('avatar', _.random(1, 15) + '.jpg');
   }
   

6. Create some method and show in DevTools
