Question

symfony 1.4和doctrine 1.2中的旧查询

$user = Doctrine_Query::create()
                ->from('User.u')
                ->innerJoin('u.State s')
                ->where('u.id = ?', $id)
                ->andWhere('u.state_id = ?', $state_id)
                ->fetchOne();

现在我在symfony2中的查询：

$repository = $this->getDoctrine()
->getRepository('FrontendAccountBundle:User');

$user = $repository->findBy(array(
    'activationId' => $activation_id), 
    array('state' => 3));

我的错误正在出现：

无法识别的字段：状态

有什么问题？

编辑：重新格式化代码

Answer 1

问题是User实体中的变量是“state”而不是“stateId”。您必须始终使用实体中的名称，而不是数据库。由于stateId位于State实体中，因此还需要完成从User到State的连接。

当需要加入时，最好使用queryBuilder或DQL。

这是一篇关于Doctrine 2 queryBuilder中的连接的帖子：doctrine 2 query builder and join tables

以下是Symfony Book for Doctrine的文档：http://symfony.com/doc/current/book/doctrine.html#entity-relationships-associations

以下是我的项目中与您的问题非常相似的示例：

    $uid = 2;
    $rep = $this->getDoctrine()->getRepository('DevondevTrackRTimeBundle:Activity');
    $q = $rep->createQueryBuilder('a')
        ->select ('a.activityId, a.startTime, a.endTime, u.username')
        ->join('a.login','u')
        ->where('u.id = :uid')
        ->setParameter('uid', $uid)
        ->getQuery();

    $acts = $q->getResult();

如果我不需要用户表中的任何内容，则查询可以写为

    $uid = 2;
    $rep = $this->getDoctrine()->getRepository('DevondevTrackRTimeBundle:Activity');
    $q = $rep->createQueryBuilder('a')
        ->where('a.login = :uid')
        ->setParameter('uid', $uid)
        ->getQuery();

    $acts = $q->getResult();

这是你的查询以同样的方式重写：

    $rep = $this->getDoctrine()->getRepository('FrontendAccountBundle:User');
    $q = $rep->createQueryBuilder('u')
        ->join('u.state','s')
        ->where ('u.id = :uid')
        ->andWhere ('s.stateId = :sid')
        ->setParameters(array('uid' => $id, 'sid' => $state_id))             
        ->getQuery(); 

    $user = $q->getSingleResult();

Answer 2

感谢彼得点亮了我一点!!!

如果您不想再次使用symfony2（-docs）和doctrine2中的愚蠢解决方案，因为您需要比symfony1.4更多的代码，就像那样http://symfony.com/doc/current/book/doctrine.html#joining-to-related-records。试试我的解决方案。

结果如下。

        $em = $this->getDoctrine()->getEntityManager();
        $user = $em->createQuery('SELECT u FROM FrontendAccountBundle:User u
              INNER JOIN FrontendAccountBundle:State s
                WHERE
                u.activation_id=:activation_id
                and
                u.state=:state_id
                ')
            ->setParameter('activation_id', $activation_id)
            ->setParameter('state_id', 3)
            ->getSingleResult();
