级联删除不 working.cascade={"remove"}

Question

我正在使用 Doctrine 2。我有一个实体，我可以在其中自我加入。连接中的两列是：

/**
 * @ORM\ManyToOne(targetEntity="Entities\wall_post", inversedBy="shared_wallpost")
 * @ORM\JoinColumn(name="wall_post_id", referencedColumnName="id")
 */
private $shared_from_wallpost;

/**
 * @ORM\OneToMany(targetEntity="Entities\wall_post", mappedBy="shared_from_wallpost", cascade={"remove"})
 */
private $shared_wallpost;

Lets say there are two posts: one id = 1001 second id = 1002 ( having wall_post_id = 1001)

now I want when I delete 1001 , post with wall_post_id 1001 gets deleted.

为此我使用了 cascade={"remove"} 但它不起作用。我的删除墙贴对象的查询：

//Removing record from table.

    $qb_1 = $em->createQueryBuilder();
                $qb_1->delete('\Entities\wall_post', 'wp');
                $qb_1->where( 'wp.id  = ?1' );
                $qb_1->setParameter('1', $wallpost_id );
                $qb_1->getQuery()->execute();
                $em -> flush();

Answer 1

对于级联={“删除”} 我们必须使用：

$em->remove($wallpost_obj);
            $em->flush();

我用过：

 $qb_1 = $em->createQueryBuilder();
                $qb_1->delete('\Entities\wall_post', 'wp');
                $qb_1->where( 'wp.id  = ?1' );
                $qb_1->setParameter('1', $wallpost_id );
                $qb_1->getQuery()->execute();
                $em -> flush();

现在级联删除正在运行。
