Question

symfony2不保存关系表（role_user）中的关系。我想要一个从用户到角色的m：n关系。

实体中是否缺少组件？

谢谢！

角色实体

 */

class Role implements RoleInterface{
    /**
     * @ORM\Column(type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;
    public function getRole() {

        return $this->role;
    }
    /**
     * @ORM\Column(name="roles", type="json_array")
     */
    private $roles =  array();
    /**
     * @ORM\ManyToMany(targetEntity = "User", inversedBy = "roles")
     *
     * @var ArrayCollection $users

    protected $users;

    /**

    {

    }

    public function setUsers($users)
    {

    }


    public function setRoles(array $roles)
    {

        return $this;

Userload Fixture

public function load(ObjectManager $manager)
    {

            $user = new User();
            $user->setUsername($i);
            $user->setIsActive(1);
            $user->setLetzterLogin(new \DateTime("2015-02-01 14:00"));
            $user->setPassword($this->encodePassword($user,"user"));
            $user->setEmail($i . "@" .$i .".de");
            $user->setVorname("Christian");
            $user->setNachname("Schade");
            $role = $manager->getRepository('UserBundle:Role')->findRoleByName("USER");
            $user->setRoles($role);
            $manager->persist($user);



        $manager->flush();



    }

Answer 1

您需要在所有者网站上设置JoinTable，请查看ORM documentation：
http://doctrine-orm.readthedocs.org/en/latest/reference/association-mapping.html

在6.8和6.9部分下，您将看到它是如何完成的

Answer 2

您需要在用户实体中编写关系，例如：

/**
 * @ORM\ManyToMany(targetEntity="Role", inversedBy="users")
 * @ORM\JoinTable(name="role_user",
 *      joinColumns={@ORM\JoinColumn(name="user_id", referencedColumnName="id")},
 *      inverseJoinColumns={@ORM\JoinColumn(name="role_id", referencedColumnName="id")}
 *      )
 */
private $roles;

Symfony不会在User＆lt; - ＆gt; Roles表中保存m：n关系
