我有以下具有多对多关系的实体: 用户
/**
* @ORM\ManyToMany(targetEntity = "Role", mappedBy = "users")
*
* @var ArrayCollection $roles;
*/
private $roles;
角色
/**
* @ORM\ManyToMany(targetEntity = "User", inversedBy = "roles")
*
* @var ArrayCollection $users
*/
protected $users;
Doctrine 生成了 3 个表: 用户 角色 用户角色
然后我添加了数据 fixture :
class FixtureLoader implements FixtureInterface {
public function load(ObjectManager $manager) {
$role = new Role();
$role->setName('Администратор');
$role->setRole('ROLE_ADMIN');
$manager->persist($role);
$user = new User();
$user->setUsername('ahmed');
$user->setEmail('ahmed@umahanov.com');
$user->setSalt(md5(time()));
$user->setIsActive(false);
$encoder = new MessageDigestPasswordEncoder('sha512',true,10);
$password = $encoder->encodePassword('admin', $user->getSalt());
$user->setPassword($password);
//$user->getUserRoles()->add($role);
$user->addRole($role);
$manager->persist($user);
$manager->flush();
}
}
当我使用控制台加载它时，只有 2 个表填充了数据，但保留多对多关系的 user_role 表是空的。
如何解决这个问题？还是我需要自己填充？

最佳答案
设置相关实体时，必须在两边都设置:
对于 User 类:
/**
* Add roles
*
* @param \Umahanov\UserBundle\Entity\Role $roles
* @return User
*/
public function addRole(\Umahanov\UserBundle\Entity\Role $roles) {
$this->roles[] = $roles;
$roles->addUser($this);
return $this;
}
