我有一个 LastTrait 对象,它与我的用户对象具有多对一关系:一个用户可以有许多不同的 lastTrait:
YOP\YourOwnPoetBundle\Entity\LastTrait:
type: entity
table: null
fields:
id:
type: integer
id: true
generator:
strategy: AUTO
traitCategoryID:
type: integer
verseID:
type: integer
manyToOne:
user:
targetEntity: User
inversedBy: lastTrait
joinColumn:
name: user_id
referencedColumnName: id
我需要知道 userID 和 traitCategoryID 来检索 verseID。所以我为我的 LastTrait 对象创建了一个存储库:
<?php
namespace YOP\YourOwnPoetBundle\Repository;
use Doctrine\ORM\EntityRepository;
class LastTraitRepository extends EntityRepository {
public function findOneByTraitCategoryID($userID, $traitCategoryID)
{
return $this->getEntityManager()
->createQuery('SELECT l
FROM YOPYourOwnPoetBundle:LastTrait l
JOIN l.user u
WHERE l.traitCategoryID = :categoryID AND u.id = :userID')
->setParameters(array(
'categoryID' => $traitCategoryID,
'userID' => $userID,
))
->getResult();
}
}
?>
但是,当我打电话时:
$lastTrait = $this->getDoctrine()
->getRepository('YOPYourOwnPoetBundle:LastTrait')
->findOneByTraitCategoryID($user->getID(), $collector->getTraitCategory()->getID());
我总是得到 NULL,即使我应该得到一个 LastTrait 对象!
我在这里做错了什么?
