php - 教义可怪的扩展 'on change'不起作用

我正在使用stof Doctrine扩展的symfony 2.6.3。

TimeStampable和SoftDeletable可以很好地工作。

同样可责怪的“在创建时”和“在更新时”也能很好地工作:

/**
 * @var User $createdBy
 *
 * @Gedmo\Blameable(on="create")
 * @ORM\ManyToOne(targetEntity="my\TestBundle\Entity\User")
 * @ORM\JoinColumn(name="createdBy", referencedColumnName="id")
 */
protected $createdBy;

/**
 * @var User $updatedBy
 *
 * @Gedmo\Blameable(on="update")
 * @ORM\ManyToOne(targetEntity="my\TestBundle\Entity\User")
 * @ORM\JoinColumn(name="updatedBy", referencedColumnName="id")
 */
protected $updatedBy;

但是“不断变化”似乎行不通。

/**
 * @var User $deletedBy
 *
 * @Gedmo\Blameable(on="change", field="deletedAt")
 * @ORM\ManyToOne(targetEntity="my\UserBundle\Entity\User")
 * @ORM\JoinColumn(name="deletedBy", referencedColumnName="id")
 */
protected $deletedBy;

我在“deletedAt”字段上配置了SoftDeletable。 SoftDeletable可以正常工作，但是从未填充deletedBy。

我如何设法使其正常工作？我只想设置删除该实体的用户ID。

最佳答案

class SoftDeleteListener
{
/**
 * @var TokenStorageInterface
 */
private $tokenStorage;

public function __construct(TokenStorageInterface $tokenStorage)
{
    $this->tokenStorage = $tokenStorage;
}

/**
 * Method called before "soft delete" system happened.
 *
 * @param LifecycleEventArgs $lifeCycleEvent Event details.
 */
public function preSoftDelete(LifecycleEventArgs $lifeCycleEvent)
{
    $document = $lifeCycleEvent->getDocument();
    if ($document instanceof SoftDeletedByInterface) {
        $token = $this->tokenStorage->getToken();

        if (is_object($token)) {
            $oldValue = $document->getDeletedBy();
            $user = $token->getUser();

            $document->setDeletedBy($user);
            $uow = $lifeCycleEvent->getObjectManager()->getUnitOfWork();
            $uow->propertyChanged($document, 'deletedBy', $oldValue, $user);
            $uow->scheduleExtraUpdate($document, array('deletedBy' => array($oldValue, $user)));
        }
    }
}

}
