Symfony不在用户处保存m:n关系<-&燃气轮机；角色表

symfony2不在关系表（角色\用户）中保存关系。 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

<?php
/**

 * User: christianschade
 * Date: 02.02.15
 * Time: 19:29
 */

namespace Chris\UserBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\Role\RoleInterface;
/**
 * Role
 * @ORM\Entity(repositoryClass="Chris\UserBundle\Entity\RoleRepository")
 * @ORM\Table(name="roles")
 */

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;

    /**
     * @return ArrayCollection
     */
    public function getUsers()
    {
        return $this->users;
    }

    /**
     * @param ArrayCollection $users
     */
    public function setUsers($users)
    {
        $this->users = $users;
    }


    public function setRoles(array $roles)
    {
        $this->roles = $roles;

        // allows for chaining
        return $this;
    }
    /**
     * @inheritDoc
     */
    public function getId()
    {
        return $this->id;
    }
}

您需要在所有者站点上设置JoinTable，请查看

ORM文档
：


在
6.8
和
6.9
部分中，您将看到它是如何完成的
您需要在用户实体中编写关系，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;

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();



    }

/**
 * @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;
