FOSUserBundle add properties - symfony

Question

i've extended FOSUserBundle with my custom User Entity in this way:
<?php
namespace Hu\UserBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use FOS\UserBundle\Entity\User as BaseUser;
use Symfony\Component\Validator\Constraints as Assert;
/**
* User
*
* #ORM\Table(name="user")
* #ORM\Entity
*/
class User extends BaseUser
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #var string
*
* #ORM\Column(name="fname", type="string", length=255)
* #Assert\NotBlank()
*/
private $fname;
// other fields...
/**
* Set fname
*
* #param string $fname
* #return UserEntity
*/
public function setFname($fname)
{
$this->fname = $fname;
return $this;
}
/**
* Get fname
*
* #return string
*/
public function getFname()
{
return $this->fname;
}
public function __construct()
{
parent::__construct();
// ...
$this->fname = setFname($fname);
}
}
But when i try to load the /register route or to add a new user by:
php app/console fos:user:create
Symfony returns me:
FatalErrorException: Error: Call to undefined function Hu\UserBundle\Entity\setFname() in /Library/WebServer/Documents/sfprojects/quattro/src/Hu/UserBundle/Entity/User.php
What's wrong in the constructor? What i miss?
Thanks a lot,

Answer 1

setFname isn't function, but it is method in your class.
so to execute it you need use $this->setFname($fname).
Also in constructor you shouldn't run methods like setters or getters (if they don't do anything except set variable or get variable)
Your constructor should look like:
public function __construct()
{
parent::__construct();
$this->fname = $fname;
}

Answer 2

the commande " php app/console fos:user:create " uses the setters of the entity User to affect data inputs from the terminal ( in the same way that Forms uses them to affect the data to an object from the < input ... > tag ) .
You can add setters for all the fields you added to your User class to solve this problem
exemple :
/**
* #var string
*
* #ORM\Column(name="fname", type="string", length=255)
* #Assert\NotBlank()
*/
private $fname;
public function setFname($fname) {
$this->fname = $fname;
}
