}
i have deleted fields in this entity and changed the default value of fields to null ('nullable = true') like this :
<?php
namespace AppBundle\Entity;
use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
/**
* FosUser
*
* #ORM\Table(name="fos_user", uniqueConstraints={#ORM\UniqueConstraint(name="UNIQ_957A6479A0D96FBF", columns={"email_canonical"}), #ORM\UniqueConstraint(name="UNIQ_957A647992FC23A8", columns={"username_canonical"}), #ORM\UniqueConstraint(name="UNIQ_957A6479C05FB297", columns={"confirmation_token"})}, indexes={#ORM\Index(name="IDX_957A647914013572", columns={"copon_id"})})
* #ORM\Entity
*/
class FosUser extends BaseUser
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer", nullable=false)
* #ORM\Id
* #ORM\GeneratedValue(strategy="IDENTITY")
*/
protected $id;

{
parent::__construct();
// your own logic
}

Answer 1

Your code is right!
Previously you haven't used FOUser class, your fos_user table have already username, emailCanonical, etc ...
Then when you extend FOSUser and update database schema, your current entity doesn't accept null value for username, etc .. (It's FOSUser logic)
Solution, you have to delete your fos_user table before updating the database schema
