OneToMany/ManyToOne Bidirectional not working

Question

Hi everyone and thanks for help,

I'm currently dealing with a problem while I want to make an OneToMany/ManyToOne Bidirectional Relationship with Doctrine2 (& Symfony2.5.6).

Here are my two classes : Voiture , and Voiture modeles

namespace Esprit\ParcBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

 /**
* @ORM\Entity
*/
class Voiture
{
/**
 * @ORM\Id
 * @ORM\GeneratedValue
 * @ORM\Column(type="integer")
 */
private $id;

/**
 * @ORM\Column(type="string")
 */
private $serie;

/**
 * @ORM\Column(type="date")
 */
private $dateM;

/**
 * @ORM\Column(type="string")
 */
private $marque;

/**
 * @ORM\Column(type="integer")
 * @ORM\ManyToOne(targetEntity="ModeleVoiture")
 * @ORM\JoinColumn(referencedColumnName="id")
 */
private $id_m;

and :

 <?php

 namespace Esprit\ParcBundle\Entity;

 use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 */
class ModeleVoiture
{
/**
 * @ORM\Id
 * @ORM\GeneratedValue
 * @ORM\Column(type="integer")
 */
private $id;

/**
 *@ORM\Column(type="string")
 */
private $libelle;

/**
 * @ORM\Column(type="string")
 */
private $pays;

when i want to phpmyadmin to check if the foreign key relationis added or no, i can't find it thank you for your help.

您需要从private $id_m;删除@ORM\\Column(type="integer") private $id_m;
