[ObjectMapper] Add support for Doctrine entities #60610

Description
Add support for Doctrine entities.
Currently I am encountering the following error:
A new entity was found through the relationship 'App\Entity\User#location' that was not configured to cascade persist operations for entity: App\Entity\Location@788. To solve this issue: Either explicitly call EntityManager#persist() on this unknown entity or configure cascade persist this association in the mapping for example #[ORM\ManyToOne(..., cascade: ['persist'])]. If you cannot find out which entity causes the problem implement 'App\Entity\Location#__toString()' to get a clue.
Example
Hi,
I have a classic User entity:
<?php
namespace App\Entity;
[...]
#[ORM\Entity(repositoryClass: UserRepository::class)]
#[ORM\Table(name: '`user`')]
class User implements UserInterface, PasswordAuthenticatedUserInterface
{
#[ORM\Id]
#[ORM\GeneratedValue]
#[ORM\Column]
private ?int $id = null;
#[ORM\Column(length: 180)]
private ?string $email = null;
#[ORM\Column]
private ?string $password = null;
#[ORM\ManyToOne]
#[ORM\JoinColumn(nullable: false)]
private ?Location $location = null;
[...]
}As well as another entity Location:
<?php
namespace App\Entity;
[...]
#[ORM\Entity(repositoryClass: LocationRepository::class)]
class Location
{
#[ORM\Id]
#[ORM\GeneratedValue]
#[ORM\Column]
private ?int $id = null;
#[ORM\Column]
private string $cityName;
#[ORM\Column(length: 255)]
private string $countryName;
[...]
}The Registration DTO is linked to the User entity. This DTO has the $location property which represents a Location entity.
<?php
namespace App\Form\Model;
[...]
#[Map(target: User::class)]
final class Registration
{
public ?string $email = null;
public ?string $plainPassword;
public ?Location $location;
[...]
}Finally, here is the controller that I use to map the Dto Registration to the User entity:
<?php
namespace App\Controller\User;
[...]
final class RegistrationController extends AbstractController
{
#[Route('/register', methods: ['GET', 'POST'])]
public function register(
#[CurrentUser] ?User $user,
Request $request,
UserPasswordHasherInterface $userPasswordHasher,
EntityManagerInterface $entityManager,
RegistrationSession $registrationSession,
ObjectMapperInterface $objectMapper,
RegistrationStep $registrationStep = RegistrationStep::Email,
): ?Response {
$registration = $registrationSession->start();
$form = $this->createForm(RegistrationForm::class, $registration, ['step' => $registrationStep]);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$registrationSession->save($form->getData());
if (Registration::isFinalStep($registrationStep)) {
$user = new User();
$objectMapper->map($registration, $user);
/** @var string $plainPassword */
$plainPassword = $registration->plainPassword;
// encode the plain password
$user->setPassword($userPasswordHasher->hashPassword($user, $plainPassword));
$entityManager->persist($user);
$entityManager->flush();
$registrationSession->terminate();
}
}
return $this->render(\sprintf('user/registration/register/%s.html.twig', u($registrationStep->value)->snake()), $parameters);
}
}The problem is when I persist then flush, I get the following error:
A new entity was found through the relationship 'App\Entity\User#location' that was not configured to cascade persist operations for entity: App\Entity\Location@788. To solve this issue: Either explicitly call EntityManager#persist() on this unknown entity or configure cascade persist this association in the mapping for example #[ORM\ManyToOne(..., cascade: ['persist'])].
