User Entity with Symfony

This documentation is based on the official Symfony Documentation with some API Platform integrations.

# Creating the Entity and Repository

You can follow the official Symfony Documentation and add the API Platform attributes (e.g. #[ApiResource]) by your own, or just use the following entity file and modify it to your needs:

<?php
// api/src/Entity/User.php

namespace App\Entity;

use ApiPlatform\Metadata\ApiFilter;
use ApiPlatform\Metadata\ApiProperty;
use ApiPlatform\Metadata\ApiResource;
use ApiPlatform\Metadata\Delete;
use ApiPlatform\Metadata\Get;
use ApiPlatform\Metadata\GetCollection;
use ApiPlatform\Metadata\Patch;
use ApiPlatform\Metadata\Post;
use ApiPlatform\Metadata\Put;
use Doctrine\ORM\Mapping as ORM;
use App\Repository\UserRepository;
use App\State\UserPasswordHasher;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;
use Symfony\Component\Security\Core\User\PasswordAuthenticatedUserInterface;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Component\Serializer\Annotation\Groups;
use Symfony\Component\Validator\Constraints as Assert;

#[ApiResource(
    operations: [
        new GetCollection(),
        new Post(processor: UserPasswordHasher::class, validationContext: ['groups' => ['Default', 'user:create']]),
        new Get(),
        new Put(processor: UserPasswordHasher::class),
        new Patch(processor: UserPasswordHasher::class),
        new Delete(),
    ],
    normalizationContext: ['groups' => ['user:read']],
    denormalizationContext: ['groups' => ['user:create', 'user:update']],
)]
#[ORM\Entity(repositoryClass: UserRepository::class)]
#[ORM\Table(name: '`user`')]
#[UniqueEntity('email')]
class User implements UserInterface, PasswordAuthenticatedUserInterface
{
    #[Groups(['user:read'])]
    #[ORM\Id]
    #[ORM\Column(type: 'integer')]
    #[ORM\GeneratedValue]
    private ?int $id = null;

    #[Assert\NotBlank]
    #[Assert\Email]
    #[Groups(['user:read', 'user:create', 'user:update'])]
    #[ORM\Column(length: 180, unique: true)]
    private ?string $email = null;

    #[ORM\Column]
    private ?string $password = null;

    #[Assert\NotBlank(groups: ['user:create'])]
    #[Groups(['user:create', 'user:update'])]
    private ?string $plainPassword = null;

    #[ORM\Column(type: 'json')]
    private array $roles = [];

    public function getId(): ?int
    {
        return $this->id;
    }

    public function getEmail(): ?string
    {
        return $this->email;
    }

    public function setEmail(string $email): self
    {
        $this->email = $email;

        return $this;
    }

    /**
     * @see PasswordAuthenticatedUserInterface
     */
    public function getPassword(): string
    {
        return $this->password;
    }

    public function setPassword(string $password): self
    {
        $this->password = $password;

        return $this;
    }

    public function getPlainPassword(): ?string
    {
        return $this->plainPassword;
    }

    public function setPlainPassword(?string $plainPassword): self
    {
        $this->plainPassword = $plainPassword;

        return $this;
    }

    /**
     * @see UserInterface
     */
    public function getRoles(): array
    {
        $roles = $this->roles;

        $roles[] = 'ROLE_USER';

        return array_unique($roles);
    }

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

        return $this;
    }

    /**
     * A visual identifier that represents this user.
     *
     * @see UserInterface
     */
    public function getUserIdentifier(): string
    {
        return (string) $this->email;
    }

    /**
     * @see UserInterface
     */
    public function eraseCredentials(): void
    {
        $this->plainPassword = null;
    }
}

The repository is same as generated by Symfony. For completeness:

<?php
// api/src/Repository/UserRepository.php

namespace App\Repository;

use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;
use Doctrine\Persistence\ManagerRegistry;
use App\Entity\User;
use Symfony\Component\Security\Core\Exception\UnsupportedUserException;
use Symfony\Component\Security\Core\User\PasswordAuthenticatedUserInterface;
use Symfony\Component\Security\Core\User\PasswordUpgraderInterface;

/**
 * @extends ServiceEntityRepository<User>
 *
 * @method User|null find($id, $lockMode = null, $lockVersion = null)
 * @method User|null findOneBy(array $criteria, array $orderBy = null)
 * @method User[]    findAll()
 * @method User[]    findBy(array $criteria, array $orderBy = null, $limit = null, $offset = null)
 */
class UserRepository extends ServiceEntityRepository implements PasswordUpgraderInterface
{
    public function __construct(ManagerRegistry $registry)
    {
        parent::__construct($registry, User::class);
    }

    public function save(User $entity, bool $flush = false): void
    {
        $this->getEntityManager()->persist($entity);

        if ($flush) {
            $this->getEntityManager()->flush();
        }
    }

    public function remove(User $entity, bool $flush = false): void
    {
        $this->getEntityManager()->remove($entity);

        if ($flush) {
            $this->getEntityManager()->flush();
        }
    }

    /**
     * Used to upgrade (rehash) the user's password automatically over time.
     */
    public function upgradePassword(PasswordAuthenticatedUserInterface $user, string $newHashedPassword): void
    {
        if (!$user instanceof User) {
            throw new UnsupportedUserException(sprintf('Instances of "%s" are not supported.', \get_class($user)));
        }

        $user->setPassword($newHashedPassword);

        $this->save($user, true);
    }
}

# Creating and Updating User Password

There’s no built-in way for hashing the plain password on POST, PUT or PATCH. Happily you can use the API Platform state processors for auto-hashing plain passwords.

First create a new state processor:

<?php
// api/src/State/UserPasswordHasher.php

namespace App\State;

use ApiPlatform\Metadata\Operation;
use ApiPlatform\State\ProcessorInterface;
use Symfony\Component\PasswordHasher\Hasher\UserPasswordHasherInterface;

/**
 * @implements ProcessorInterface<User, User|void>
 */
final readonly class UserPasswordHasher implements ProcessorInterface
{
    public function __construct(
        private ProcessorInterface $processor,
        private UserPasswordHasherInterface $passwordHasher
    )
    {
    }

    /**
     * @param User $data
     */
    public function process(mixed $data, Operation $operation, array $uriVariables = [], array $context = []): User
    {
        if (!$data->getPlainPassword()) {
            return $this->processor->process($data, $operation, $uriVariables, $context);
        }

        $hashedPassword = $this->passwordHasher->hashPassword(
            $data,
            $data->getPlainPassword()
        );
        $data->setPassword($hashedPassword);
        $data->eraseCredentials();

        return $this->processor->process($data, $operation, $uriVariables, $context);
    }
}

Then bind it to the ORM persist processor:

# api/config/services.yaml

services:
  # ...

  App\State\UserPasswordHasher:
    bind:
      $processor: '@api_platform.doctrine.orm.state.persist_processor'

You may have wondered about the following lines in our entity file we created before:

    operations: [
        ...
        new Post(processor: UserPasswordHasher::class),
        new Put(processor: UserPasswordHasher::class),
        new Patch(processor: UserPasswordHasher::class),
        ...
    ],

This just means we want to run the new created state processor to these specific operations. So we’re done. Create a new user, change the password and enjoy!
