Phalcon ORM doesn't work - php

Question

I am learning phalcon. I have some problems with models.
Function FindFirst returns nothing, also it doesn't show any errors or exceptions. Here is my code:
public function indexAction()
{
$user = Users::findFirst(1);
var_dump($user);
}
And all what I get - is empty page.
Here is my Users Model:
<?php
namespace Models\User;
use Phalcon\Mvc\Model\Validator\Email as Email;
class Users extends \Phalcon\Mvc\Model
{
/**
*
* #var integer
*/
public $id;
/**
*
* #var string
*/
public $login;
/**
*
* #var string
*/
public $email;
public function initialize()
{
$this->setSource("users");
}
/**
* Validations and business logic
*/
public function validation()
{
$this->validate(
new Email(
array(
'field' => 'email',
'required' => true,
)
)
);
if ($this->validationHasFailed() == true) {
return false;
}
}
/**
* Independent Column Mapping.
* Keys are the real names in the table and the values their names in the application
*
* #return array
*/
public function columnMap()
{
return array(
'id' => 'id',
'login' => 'login',
'email' => 'email'
);
}
}
Some additional information:
I have edited config files.
Phalcon version is 2.0

First you should ensure that the User model you are trying to load is in the right namespace, what means in your case you should use:
$user = \Models\User\Users::findFirst(1);
And to retrieve an output (depending on your index.php but probably this way) you should return "something", otherwise the buffer will be empty and nothing will be displayed.
