Symfony很新 - 我能夠成功刪除用戶，但我無法刪除與用戶關聯的所有產品。我的目標是單擊管理後端中的按鈕並刪除用戶以及與用戶關聯的所有產品。在刪除用戶時刪除與用戶關聯的產品
我嘗試了幾種方法，並在自己的追求中失去了一點點。我恢復了原來的代碼，成功地允許我刪除用戶。
任何反饋將不勝感激。不知道是否需要包含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)

// create the user event and dispatch it
