Question

我试图在父（Report）存储库中使用子类来执行leftJoin而不是获取＆＃39; 500内部服务器错误＆＃39;。我这样做如下。这里ReportCallOut表＆＃39; id＆＃39;（PK）字段是报告表＆＃39; id＆＃39;（PK）的外键。

    class ReportRepository extends EntityRepository
            {
                public function getPage($page = 1, $perPage = null, $filter = null) {

                    $qb = $this->createQueryBuilder('r')                   
                               ->leftJoin('r.client', 'c')                             
 ->leftJoin('ACMEModulesReportCentreBundle:ReportCallOut', 'rc', 'WITH', 'r.id=rc.id')
                               ->leftJoin('r.site', 's')                       
                               ->leftJoin('r.status', 'st');
            }

在我打印$ qb-＆gt; getQuery（） - ＆gt; getSQL（）时添加leftJoin之后比得到500内部服务器错误。

ReportController.php

class ReportCentreController extends ModuleController
{
    public function indexAction(Request $request, $page)
    {

        $request->getSession()->set('signBack', $request->getUri());


        $reportsRepository = $this->getDoctrine()
            ->getRepository('ACMEModulesReportCentreBundle:Report');

        $perPage = $this->container->getParameter('pagination_per_page');

        $filter = $this->get('acme_core.filters')->getFilter();
        $filter['division'] = $this->division;

        if ($this->isGranted('ROLE_REPORT_CENTRE_CAN_VIEW_OWN_REPORTS', $this->module)) {
            $filter['createdBy'] = $this->getUser();
        }


        $reportsPaginator = $reportsRepository->getPage($page, $perPage, $filter);

    }
}

ReportRepository.php

class ReportRepository extends EntityRepository
        {
            public function getPage($page = 1, $perPage = null, $filter = null) {

                $qb = $this->createQueryBuilder('r')                   
                           ->leftJoin('r.client', 'c')
                           ->leftJoin('r.site', 's')                       
                           ->leftJoin('r.status', 'st');
        }

Report.php

    abstract class Report {


        /**
         * @ORM\Column(type="integer")
         * @ORM\Id
         * @ORM\GeneratedValue(strategy="AUTO")
         */
        protected  $id;

        /**
        * @Gedmo\Versioned
        * @ORM\Column(type="string", length=255, nullable=true)
        */
    }

ReportCallOut.php

class ReportCallOut extends Report {

       // protected $locked = false;
        /**
        * @Gedmo\Versioned
        * @ORM\Column(type="date", nullable=true)
        */
        private $date;

        /**
        * @Gedmo\Versioned
        * @ORM\Column(type="time", nullable=true)
        */
        private $time;

        /**
        * @Gedmo\Versioned
        * @ORM\Column(type="string", length=255, nullable=true)
        */
        protected $job;
    }

检查此代码，如果不起作用，则分享您的实体文件＆＃34; ReportCallOut＆＃34;和＆＃34;客户＆＃34;。

$em = $this->getDoctrine()->getManager();
$clientRepository = $em->getRepository("AppBundle:client");
$where = ' c.cId=:id and c.cStatus !=9 ';

if (!empty($searchKey)) {
    $where .= " AND (r.rName LIKE '%" . $searchKey . "%'
                        OR c.cFirstName LIKE '%" . $searchKey . "%'
                        OR c.cLastName LIKE '%" . $searchKey . "%') ";
}

$qb = $this->createQueryBuilder('r')
        ->select('r.rId,c.cId')
        ->leftJoin('r.client', 'c')
        ->leftJoin('ACMEModulesReportCentreBundle:ReportCallOut', 'rc', 'WITH', 'r.rId=rc.rcId')
        ->leftJoin('r.site', 's')
        ->leftJoin('r.status', 'st')
        ->where($where)
        ->setParameter('id', $id)
        ->getQuery();
$resultData = $qb->getResult(\Doctrine\ORM\Query::HYDRATE_ARRAY);
