删除用户时删除与用户关联的产品

标签： php mysql symfony

Symfony很新 - 我能够成功删除用户，但是我很难删除与用户关联的所有产品。我的目标是单击管理员后端中的按钮并删除用户以及与该用户关联的所有产品。

我尝试了几种方法，并且在我自己的追求中有点迷失。我恢复了原来的代码，成功地允许我删除用户。

我们将不胜感激。不确定我是否还需要包含VendorRepository。

UserRepository.php 

public function delete($id)
{
    // get access to the entity manager
    $em = $this->getEntityManager();
    // get the user from the repository by id
    $user = $em->getReference('Thinkfasttoys\Core\Entity\user', $id);
    // use built in methods to delete the user
    $em->remove($user);
    // update the database with the change
    $em->flush();
}

ProductRepository.php 

public function deleteAllProductsByVendorId($vendorId)
{
    // @Todo: revisit this at a later date and determine if the vendor id is actually required
    $qb = $this->getEntityManager()->createQueryBuilder();
    $qb->delete("Thinkfasttoys\Mapwatch\Entity\Product","p")
        ->andWhere($qb->expr()->eq('p.vendor', ':vendor'))
        ->setParameter(':vendor', $vendorId)
        ->getQuery()
        ->getResult();
}

public function delete($id)
{
    // @Todo: switch to vendor id, instead of user id
    $qb = $this->getEntityManager()->createQueryBuilder();
    $qb->delete("Thinkfasttoys\Mapwatch\Entity\Product","p")
        ->andWhere($qb->expr()->eq('p.vendor', ':vendor'))
        ->setParameter(':vendor', $vendorId)
        ->getQuery()
        ->getResult();
}

服务 - Users.php 

    public function delete($id)
{
    $this->repository->delete($id);
}

控制器 - AdminController 

    /**

 * @Template
 */
public function deleteAction($id)
{
    $dispatcher = $this->container->get('event_dispatcher');

    $this->get('users')->delete($id);

    // create the user event and dispatch it
    $event = new UserEvent($id);
    $dispatcher->dispatch(UserEvents::USER_DELETED, $event);

    $this->get('session')->getFlashBag()->add('notice-success', 'User deleted successfully.');

    return $this->redirect($this->generateUrl('admin_user_list'));
}

答案 0 :(得分：1)

好的，所以我没有看到用户实体与这些产品之间的关系。

你可以为用户对产品设置一对多（xref / join table /无论你怎么称呼它），然后让Doctrine为你处理它。

/**
  * @var Collection
  * @OneToMany(targetEntity="UserProductsXref",mappedBy="user", cascade=
{"persist","remove"})
  */
 private $products;
}

或者，继续看似你的意图。触发某些存储库方法并以编程方式删除关联的行。使用deleteAllProductsByVendorId()的方法究竟与您的方法无关？
