了解 Symfony 5 Doctrine ManyToOne 关系概念与用户和角色

Question

我试图理解 Doctrine ORM 关系概念，因为据我所知，我花了很多时间来创建一个非常简单的用例，但是，我没能做到，因为我有知识匮乏...

这是我的问题：我有 2 个实体，UserApp 和 RoleApp。

我希望有可能管理来自用户的角色，而不是硬编码角色，以数组格式直接进入用户 table。所以要做到这一点，我有一个经典的外键 role_id 到 user_app table，它将主键引用到 role_app table.

我需要为每个用户获取他的角色，并以 Symfony 身份验证所需的正确格式引入它：

        class UserApp implements UserInterface, \Serializable{
    .....
    /**
     * @var UserRole
     * @ORM\ManyToOne(targetEntity="App\Entity\UserRole")
     * @ORM\JoinColumn(nullable=false)
     *
     */
    private $role;

    public function getUserRole(): array{ // I know it's wrong but I don't know what is the right type to get 

        return $this->role->getUserRole($this);
    }

    /**
     * Returns the roles or permissions granted to the user for security.
     */
    public function getRoles(): array{
    //$role = ["ADMIN_USER"];
    $role = $this->getUserRole();
    dump($role);

    return array_unique($role);


class UserRole{
    /**
     * @ORM\Column(type="json")
     */
    private $appRole = [];

    public function getUserRole(UserApp $user): ?array
    {
        $userRoleRepository = new UserRoleRepository();
        $userRole[] = $userRoleRepository->find(1);
        dump($userRole);
        return $userRole;
    }

}

但是这段代码没有为 Symfony 身份验证的用户角色需求提供正确的格式:(

终于如愿以偿了；这是我的解决方案，我希望它能帮助...

   class UserApp implements UserInterface, \Serializable
   {
  ....
      /**
     * @var UserRole
     * @ORM\ManyToOne(targetEntity="App\Entity\UserRole")
     * @ORM\JoinColumn(nullable=false)
     *
     */
    private $role;

    public function getUserRole(): UserRole
    {
        return $this->role->getRoleUser($this);
    }

    /**
     * Returns the roles or permissions granted to the user for security.
     * it's for authentification compliance
     */
    public function getRoles(): array
    {
        $arrRole = $this->getUserRole()->getAppRole();
        return array_unique($arrRole);
    }

    ......

    class UserRole{

    .....
    /**
     * @ORM\Column(type="json")
     */
    private $appRole = [];//For authentification compliance

    .....
   public function getRoleUser(UserApp $user): ?self
    {
        return $this;
    }`enter code here`
