How to withdraw in Ext.grid.Panel the value field of a linked table?

Hello! Started to learn extJS and stalled.

There are two tables:

Table users: fields [
 id int, 
 login string, 
 id_status int (refers to the id field of the table get_status)
Table get_status: fields [
 id int, 
 string status_name

I want to display Ext.grid.Panel field:
login from users and status_name from get_status appropriate id_status from users

From Hyde took the conclusion in Ext.grid.Panel one table

The model for the users table:

Ext.define('User', {
 extend: 'Ext.data.Model',

 idProperty: 'id',

 fields: [
{
 name: 'id',
 type: 'int'
},
{
 name: 'login',
 type: 'string'
 } 
{
 name: 'id_status',
 type: 'string'
}
]
 });

Downloadable data:

var users = Ext.create('Ext.data.Store', {
 model: 'User',
 autoLoad: true,
 proxy: {
 type: 'ajax',
 url: 'users.php',
 reader: {
 type: 'json',
 root: 'users'
}
}
 });

Output in Ext.grid.Panel:

Ext.create('Ext.grid.Panel', {
 title: 'Users',
 height: 200,
 width: 600,
 store: users,
 columns: [
{
 header: 'ID',
 dataIndex: 'id'
},
{
 header: 'Login',
 dataIndex: 'login'
},
{
 header: 'Status',
 dataIndex: 'id_status'
}
],
 renderTo: Ext.getBody()
 });

Tell me, how to output related values from the table get_status?
