Models

Using Ember models to better structure data

Models are how Ember manages properties of data objects. These are most frequently used with data coming from an API or other third-party, and controlled using the ember-data add-on. The basic setup of one looks like this:

import DS from 'ember-data';

export default DS.Model.extend({
  name     : DS.attr('string'),
  age      : DS.attr('integer'),
  alive    : DS.attr('boolean'),
  children : DS.hasMany('child'),
  parent   : DS.belongsTo()
});

Models can also use computed properties in case some values must be created using others. The properties put in as arguments, whenever they change, will update the computed properties. Just don’t change any values within computed properties!

import { computed } from '@ember/object';

  full_name: computed('first_name', 'last_name', function(){
    return `Hello, my name is ${this.get('first_name')} ${this.get('last_name')}`;
  })
