All our models will inherit from a base model, which will be used to specify the following command:

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

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

We used the schema configuration in the last chapter, but now that we're about to use it with multiple models, it really comes into its own. In each of the models that inherit from BaseModel, the model's name will be inserting into the proxy URL in place of the entityName token. This avoids duplicating the URL configuration across multiple models. We can now create our LogEntry model as per our design:

// app/model/LogEntry.js
Ext.define('Instrumatics...
