Php 语义错误行0，列140靠近'；Q内部联接'；：错误：类搜索\serachBundle\Entity\Person没有名为Qualification的关联

这个代码有什么问题

我想创建具有多重联接的查询，但不幸的是显示了此错误

[这是我的SearchController]

class SearchController extends Controller {

public function indexAction() {
    $em = $this->get('doctrine.orm.entity_manager');
    $users = $em 
            ->createQueryBuilder('P')
            ->select('P.pname, Q.qname,P.gender,P.phone,P.yearsOfExperience,P.graduationYear,c.cname')
            ->add('from', 'serachBundle:Person P')
            ->Join('P.Qualification', 'Q')
            ->Join('Q.Category', 'c')
            ->where('P.qualificationId=Q.id')
            ->andwhere('Q.categoryId=c.id')
            ->getQuery();
    $user = $users->getResult();

    print_r($user);
    //qualification
    $Qlist = $this->getDoctrine()
            ->getRepository('serachBundle:qualification')
            ->findAll();
    //category
    $Catlist = $this->getDoctrine()
            ->getRepository('serachBundle:category')
            ->findAll();

    return $this->render('serachBundle:Default:Search.html.twig', array('user' => $user, 'Qlist' => $Qlist, 'Catlist' => $Catlist));
}

这是我的个人实体

您将这些关系命名为$qualificationid，因此您应该将查询设置为如下所示：

->Join('P.qualificationid', 'Q')
->Join('Q.categoryid', 'c')

记住在存储库类中进行所有查询。请尝试将您的捆绑包从serach重命名为search:-D
