Code, code, and more code

It's time to get our hands dirty and put fingers to keyboards. As always, we generated a new base application using Sencha Cmd and will use the resulting "main" view as a starting point for our user interface. First though, let's flesh out the data layer that we designed earlier:

// app/model/BaseModel.js
Ext.define('Alcohology.model.BaseModel', {
    extend: 'Ext.data.Model',

    schema: {
        namespace: 'Alcohology.model',
        urlPrefix: 'http://localhost:3000',
        proxy: {
            type: 'rest',
            url: '{prefix}/{entityName:uncapitalize}'
        }
    }
});

We've used a base model in previous chapters because it gives us a good way of centralizing proxy configuration. The models that inherit from it are all straightforward, as shown in the following code:

// app/model/CartItem.js
Ext.define('Alcohology.model.CartItem', {
    extend: 'Alcohology...
