Persist entity on non persisted field change - symfony

Question

I've an entity with a plainPassword and a password attribute. In form, I map on the plainPassword. After, when the user valid the form, I do password validation on the plainPassword.
To encode the password, I use an EventSubscriber that listen on prePersist and preUpdate. It works well for the register form, because it's a new entity, the user fill some persisted attributes, then doctrine persist it and flush.
But, when I just want to edit the password, it doesn't work, I think it's because the user just edit a non persisted attribute. Then Doctrine doesn't try to persist it. But I need it, to enter in the Subscriber.
Someone know how to do it ? (I've a similar problem in an other entity) For the moment, I do the operation in the controller...
Thanks a lot.
My UserSubscriber
class UserSubscriber implements EventSubscriber
{
private $passwordEncoder;
private $tokenGenerator;
public function __construct(UserPasswordEncoder $passwordEncoder, TokenGenerator $tokenGenerator)
{
$this->passwordEncoder = $passwordEncoder;
$this->tokenGenerator = $tokenGenerator;
}
public function getSubscribedEvents()
{
return array(
'prePersist',
'preUpdate',
);
}
public function prePersist(LifecycleEventArgs $args)
{
$object = $args->getObject();
if ($object instanceof User) {
$this->createActivationToken($object);
$this->encodePassword($object);
}
}
public function preUpdate(LifecycleEventArgs $args)
{
$object = $args->getObject();
if ($object instanceof User) {
$this->encodePassword($object);
}
}
private function createActivationToken(User $user)
{
// If it's not a new object, return
if (null !== $user->getId()) {
return;
}
$token = $this->tokenGenerator->generateToken();
$user->setConfirmationToken($token);
}
private function encodePassword(User $user)
{
if (null === $user->getPlainPassword()) {
return;
}
$encodedPassword = $this->passwordEncoder->encodePassword($user, $user->getPlainPassword());
$user->setPassword($encodedPassword);
}
My user Entity:
class User implements AdvancedUserInterface, \Serializable
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #ORM\Column(name="email", type="string", length=255, unique=true)
* #Assert\NotBlank()
* #Assert\Email()
*/
private $email;
/**
* #Assert\Length(max=4096)
*/
private $plainPassword;
/**
* #ORM\Column(name="password", type="string", length=64)
*/
private $password;
ProfileController:
class ProfileController extends Controller
{
/**
* #Route("/my-profile/password/edit", name="user_password_edit")
* #Security("is_granted('IS_AUTHENTICATED_REMEMBERED')")
*/
public function editPasswordAction(Request $request)
{
$user = $this->getUser();
$form = $this->createForm(ChangePasswordType::class, $user);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
// Encode the password
// If I decomment it, it's work, but I want to do it autmaticlally, but in the form I just change the plainPassword, that is not persisted in database
//$password = $this->get('security.password_encoder')->encodePassword($user, $user->getPlainPassword());
//$user->setPassword($password);
$em = $this->getDoctrine()->getManager();
$em->flush();
$this->addFlash('success', 'Your password have been successfully changed.');
return $this->redirectToRoute('user_profile');
}
return $this->render('user/password/edit.html.twig', [
'form' => $form->createView(),
]);
}
}

You can force Doctrine to mark an object as dirty by manipulating the UnitOfWork directly.
$em->getUnitOfWork()->scheduleForUpdate($entity)
However, I do strongly discourage this approach as it violates carefully crafted abstraction layers.
