Symfony 4.4 security get user with relation entity data after login

Question

I'm using the security bundle for Symfony 4.4.

My "User" entity is related to the "Info" entity on OneToOne.

When I'm logged I want to have "Info" data without extra query.

for exemple in my controller (after login)

when I use $this->getUser();

I have

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

Expected result

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

In my guard

in getUser method of my guard I'm using UserRepository for find my user by email.

// \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()
            ;
    }

but I'm loosing the entity Info data after my login.

How to keep my relation entity data after login ?

Answer 1

It's a very good question I find because it's really often met by beginners. The link between a custom provider and the getUser() method is not always obvious.
Often the user is not alone in an application, he comes with an address, a team, a size, a color, a packet of information that it is useful to have on hand everywhere without making additional requests.
