Sencha ExtJS Model examples

Here are some Sencha ExtJS Model examples, from the official Sencha docs.

Define a User:

Ext.define('User', {
    extend: '',
    fields: [
        {name: 'name',  type: 'string'},
        {name: 'age',   type: 'int', convert: null},
        {name: 'phone', type: 'string'},
        {name: 'alive', type: 'boolean', defaultValue: true, convert: null}

    changeName: function() {
        var oldName = this.get('name'),
            newName = oldName + " The Barbarian";

        this.set('name', newName);

Create a User:

var user = Ext.create('User', {
    id   : 'ABCD12345',
    name : 'Conan',
    age  : 24,
    phone: '555-555-5555'

user.get('name'); //returns "Conan The Barbarian"


Ext.define('User', {
    extend: '',
    fields: [
        {name: 'name',     type: 'string'},
        {name: 'age',      type: 'int'},
        {name: 'phone',    type: 'string'},
        {name: 'gender',   type: 'string'},
        {name: 'username', type: 'string'},
        {name: 'alive',    type: 'boolean', defaultValue: true}

    validations: [
        {type: 'presence',  field: 'age'},
        {type: 'length',    field: 'name',     min: 2},
        {type: 'inclusion', field: 'gender',   list: ['Male', 'Female']},
        {type: 'exclusion', field: 'username', list: ['Admin', 'Operator']},
        {type: 'format',    field: 'username', matcher: /([a-z]+)[0-9]{2,3}/}


var instance = Ext.create('User', {
    name: 'Ed',
    gender: 'Male',
    username: 'edspencer'

var errors = instance.validate();

Define a proxy:

Ext.define('User', {
    extend: '',
    fields: ['id', 'name', 'email'],

    proxy: {
        type: 'rest',
        url : '/users'

Use the proxy:

var user = Ext.create('User', {name: 'Ed Spencer', email: ''});; //POST /users

Loading data via the model proxy:

//get a reference to the User model class
var User = Ext.ModelManager.getModel('User');

//Uses the configured RestProxy to make a GET request to /users/123
User.load(123, {
    success: function(user) {
        console.log(user.getId()); //logs 123
