EmberJS - Defining Models

Model is a class that extends the functionality of the Ember Data which specifies relationships with other objects. In Emberjs, every route has an associated model and when a user refreshes the page, the contents of page should be represented by a model.

The model can be created by using the following command −

ember generate model model_name

It creates the file structure under app/models/model_name.js as shown below −

import DS from 'ember-data';
export default DS.Model.extend ({
});

Defining Attributes

The DS.attr is used to specify attributes for a model. This also takes an optional second parameter as hash.

For instance −

import DS from 'ember-data';

export default DS.Model.extend ({
   bookName: DS.attr(),
   authorName: DS.attr()
});
