SonataUserBundle User entity doesn't map changes

Question

I want to make the email field optional. I read that i need to use @AttributeOverrides annotation. My Application\Sonata\UserBundle\Entity\User class:

namespace Application\Sonata\UserBundle\Entity;

use Sonata\UserBundle\Entity\BaseUser as BaseUser;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;

/**
 *
 * @ORM\Entity
 * @ORM\Table(name="gm_user")
 * @AttributeOverrides({
 *      @ORM\AttributeOverride(name="email", column=@ORM\Column(nullable=true)),
 *      @ORM\AttributeOverride(name="emailCanonical", column=@ORM\Column(nullable=true, unique=false))
 * })
 */
class User extends BaseUser
{

    /**
     * @var integer $id
     *
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * Get id
     *
     * @return integer $id
     */
    public function getId()
    {
        return $this->id;
    }

}

When I'm trying to change schema by php app/console doctrine:schema:update --force I get: Nothing to update - your database is already in sync with the current entity metadata.

Answer 1

Problem solved! Everything works after:

1. Deleting files under Application\Sonata\UserBundle\Resources\config\doctrine\ directory
2. Running php app/console doctrine:schema:update --force
