Symfony 4.4 安全在登录后获取具有关系实体数据的用户

问题描述

我正在使用 Symfony 4.4 的安全包。

我的“用户”实体与 OnetoOne 上的“信息”实体相关。

当我登录时,我希望获得“信息”数据而无需额外查询

以我的控制器为例(登录后)

当我使用 $this->getUser();

我有

App\Entity\User\User {#1705 ▼
  -id: 1
  -email: "email@email.com"
  -roles: array:1 [▶]
  -password: "password"
  -info: Proxies\__CG__\App\Entity\User\Info {#1716 ▼
    +__isInitialized__: false
    -id: 1
    -firstname: null
    -lastname: null
  }
}

预期结果

App\Entity\User\User {#1705 ▼
  -id: 1
  -email: "email@email.com"
  -roles: array:1 [▶]
  -password: "password"
  -info: Proxies\__CG__\App\Entity\User\Info {#1716 ▼
    +__isInitialized__: true
    -id: 1
    -firstname: "Firstname"
    -lastname: "Lastname"
  }
}

在我身边

在我的守卫的 getUser 方法中,我使用 UserRepository 通过电子邮件查找我的用户

// \App\Security\AppCustomAuthenticator


    public function getUser($credentials,UserProviderInterface $userProvider)
    {
        // Load / create our user however you need.
        // You can do this by calling the user provider,or with custom logic here.
        $user = $this->userRepository->findUserByEmail($credentials['email']);

        if (!$user) {
            // fail authentication with a custom error
            throw new CustomUserMessageAuthenticationException('User not found');
        }

        return $user;
    }
// \App\Repository\User\UserRepository

    public function findUserByEmail(string $email): ?User
    {
        return $this->createqueryBuilder('user')
                    ->addSelect('user_info')
                    ->leftJoin('user.info','user_info')
                    ->andWhere('user.email = :email')
                    ->setParameter('email',$email)
                    ->getQuery()
                    ->getoneOrNullResult()
            ;
    }

但我在登录后丢失了实体 Info 数据。

登录后如何保留我的关系实体数据?

解决方法

我发现这是一个很好的问题,因为初学者确实经常遇到它。自定义提供程序和 getUser() 方法之间的联系并不总是很明显。
在应用程序中,用户通常并不孤单,他会提供地址、团队、尺寸、颜色和一包信息,这些信息随处可见,无需额外请求。

我遇到了同样的问题,如果有人一直在寻找简单的解决方案。

使您的存储库实现 UserProviderInterface,添加 3 个必需的方法(loadUserByUsernamerefreshUsersupportsClass),修改 loadUserByUsername 方法以加入想要 Doctrine 关系并修改 security.yaml 以使用您的 UserRepository 作为自定义提供程序。
