这是我的实体ObjektHistory：

namespace MBS\AllgemeinBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * ObjektHistory
 */
class ObjektHistory
{
  /**
   * @var \DateTime
   */
  private $datum;

  /**
   * @var boolean
   */
  private $typ;

  /**
   * @var boolean
   */
  private $outbox;

  /**
   * @var integer $uid
   *
   * @ORM\Column(name="id", type="integer", nullable=false)
   * @ORM\Id
   */
  private $id;

  /**
   * @var \MBS\AllgemeinBundle\Entity\Objekt
   */
  private $idSubunternehmer;

  /**
   * @var \MBS\AllgemeinBundle\Entity\Objekt
   */
  private $objektnummer;


  /**
   * Set datum
   *
   * @param \DateTime $datum
   * @return ObjektHistory
   */
  public function setDatum($datum)
  {
     $this->datum = $datum;

     return $this;
  }

  /**
   * Get datum
   *
   * @return \DateTime 
   */
  public function getDatum()
  {
     return $this->datum;
  }

 /**
  * Set typ
  *
  * @param boolean $typ
  * @return ObjektHistory
  */
 public function setTyp($typ)
 {
    $this->typ = $typ;

    return $this;
 }

 /**
  * Get typ
  *
  * @return boolean 
  */
 public function getTyp()
 {
    return $this->typ;
 }

 /**
  * Set outbox
  *
  * @param boolean $outbox
  * @return ObjektHistory
  */
 public function setOutbox($outbox)
 {
    $this->outbox = $outbox;

    return $this;
 }

 /**
  * Get outbox
  *
  * @return boolean 
  */
 public function getOutbox()
 {
    return $this->outbox;
 }

 /**
  * Get id
  *
  * @return integer 
  */
 public function getId()
 {
    return $this->id;
 }

 /**
  * Set idSubunternehmer
  *
  * @param \MBS\AllgemeinBundle\Entity\Objekt $idSubunternehmer
  * @return ObjektHistory
  */
 public function setIdSubunternehmer(\MBS\AllgemeinBundle\Entity\Objekt $idSubunternehmer = null)
 {
    $this->idSubunternehmer = $idSubunternehmer;

    return $this;
 }

 /**
  * Get idSubunternehmer
  *
  * @return \MBS\AllgemeinBundle\Entity\Objekt 
  */
 public function getIdSubunternehmer()
 {
    return $this->idSubunternehmer;
 }

 /**
  * Set objektnummer
  *
  * @param \MBS\AllgemeinBundle\Entity\Objekt $objektnummer
  * @return ObjektHistory
  */
 public function setObjektnummer(\MBS\AllgemeinBundle\Entity\Objekt $objektnummer = null)
 {
    $this->objektnummer = $objektnummer;

    return $this;
 }

 /**
  * Get objektnummer
  *
  * @return \MBS\AllgemeinBundle\Entity\Objekt 
  */
 public function getObjektnummer()
 {
    return $this->objektnummer;
 }
}

这是我的控制器：

namespace MBS\AllgemeinBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;
use MBS\AllgemeinBundle\Entity\ObjektHistory;


class DefaultController extends Controller
{
public function indexAction()
{
    $securityContext = $this->container->get( 'security.context' );
    if( $securityContext->isGranted( 'IS_AUTHENTICATED_FULLY' ) )
    {
        $em = $this->getDoctrine()->getManager();
        $objektHistoryRepo = $em->getRepository( 'MBSAllgemeinBundle:ObjektHistory' )
                                ->findBy(array("typ" =>2) , array('datum' => 'DESC'));

        return $this->render(
            'MBSAllgemeinBundle:Default:index.html.twig',
            array(
                "History" => $objektHistoryRepo
            )
        );
    }
    else
    {
        return $this->redirect($this->generateUrl('fos_user_security_login'));
    }
}
}

当我尝试使用

在资源库中搜索时

- ＆gt; findBy（数组（＆＃34; objektnummer＆＃34; =＆gt; 1234567），数组（＆＃39;数据＆＃39; =＆gt;＆＃39; DESC＆＃39;））;

我收到了错误

A single-valued association path expression to an entity with a composite primary key is not supported. Explicitly name the components of the composite primary key in the query.

我做错了什么？

Answer 1

我认为 objektHistory 实体中的ManyToOne关系应该像这样定义：

<many-to-one field="objektnummer" target-entity="Objekt" join-column="objektnummer">
   <join-column name="id_subunternehmer" referenced-column-name="objektnummer" />
</many-to-one>

您无需在实体中定义这些索引

不要从相关表中获取字段
