原则映射2级继承

Question

I defined a mapping for

/**
 * Identite entity
 * @ORM\Entity
 * @ORM\Table(name="identite")
 * @ORM\InheritanceType("JOINED")
 * @ORM\DiscriminatorColumn(name="discr", type="string")
 * @ORM\DiscriminatorMap({"identite" = "Identite","candidat" = "Candidat","consultant"="Consultant","staff"="Staff" })
 */
class Identite extends ObjetEtat{


    /**
     * @var integer
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id; 
    /**
     * @var string
     *
     * @ORM\Column(name="nomidentite", type="string", length=200, nullable=true)
     */
    private $nomidentite;}

and I have the mapping of the super Class:

/**
 * Identite entity
 * @ORM\Entity
 * @ORM\Table(name="objetetat")
 * @ORM\InheritanceType("JOINED")
 * @ORM\DiscriminatorColumn(name="discrimin", type="string")
 * @ORM\DiscriminatorMap({"objetetat" = "ObjetEtat","identite" = "Sigmatis\SigBundle\Entity\Identites\Identite" })
 */

class ObjetEtat {
    //put your code here

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

And this is the third level of my hierarchy :

/**
 * Candidat entity
 * @ORM\Entity
 * @ORM\Table(name="candidat")

 */

class Candidat extends Identite {
}

After updating my schema : I don't find the field "discr " of my table Identite . Do I miss something ??

您应该将@ORM\\DiscriminatorColumn和@ORM\\DiscriminatorMap注释放在超类上，而不是子类上
