Doctrine inserting on POST_WRITE event with Symfony 5 and APIplatform - php

Question

I want to add a new UserTeam(which get a team, a user and a role) each time a User create a Team. I created an event subscriber TeamFirstUserAdminSubscriber.php but it doesn't work and I have no error message.
here is my database model:
and here is the file TeamFirstUserAdminSubscriber.php
<?php
namespace App\Events;
use ApiPlatform\Core\EventListener\EventPriorities;
use App\Entity\Team;
use App\Entity\UserTeam;
use App\Repository\RoleUserTeamRepository;
use App\Repository\TeamRepository;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpKernel\Event\ViewEvent;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\Security\Core\Security;
class TeamFirstUserAdminSubscriber implements EventSubscriberInterface
{
private $security;
private $repository;
private $repositoryT;
private $manager;
public function __construct(Security $security, RoleUserTeamRepository $repository, TeamRepository $repositoryT, EntityManagerInterface $manager)
{
$this->security = $security;
$this->repository = $repository;
$this->repositoryT = $repositoryT;
$this->manager = $manager;
}
public static function getSubscribedEvents()
{
return[
KernelEvents::VIEW => ['setInstanceUserTeam', EventPriorities::POST_WRITE],
];
}
public function setInstanceUserTeam(ViewEvent $event)
{
$team = $event->getControllerResult();
$method = $event->getRequest()->getMethod();
if($team instanceof Team && $method === 'POST')
{
//get the user connected
$user = $this->security->getUser();
//get the last team created
$lastTeam = $this->repositoryT->findLastTeamCreated();
//get the admin role (NOT the symfony one)
$admin = $this->repository->findOneByRoleAdmin('Admin');
//should create a new UserTeam instance with the User, the Team and the RoleUserTeam wanted
$userTeam = new UserTeam();
$userTeam->setUser($user);
$userTeam->setTeam($lastTeam);
$userTeam->setRoleUserTeam($admin);
$manager = $this->manager;
$manager->persist($userTeam);
$manager->flush();
}
}
The new UserTeam is not created in the databse when I try it out with postman, but the Team is well created.
I think I am missing something but I don't know what.
Could anyone help me ?

Answer 1

I can't see your full code(controller, forms etc), but you can achieve this without an event listener. As you already know, what team to be assigned for a user, why don't you assign that on the entity when creating the user object. For example if you using form in the controller
public function addAdminUser(Request $request, RoleUserTeamRepository $repository, TeamRepository $repositoryT, EntityManagerInterface $manager)
{
$user = new User();
$form = $this->createForm(UserForm::class, $user);
$form->handleRequest($form);
 
if ($form->isSubmitted && $form->isValid()) {
//get the last team created
$lastTeam = $this->repositoryT->findLastTeamCreated();
//get the admin role (NOT the symfony one)
$admin = $this->repository->findOneByRoleAdmin('Admin');

//should create a new UserTeam instance with the User, the Team and the
RoleUserTeam wanted
$userTeam = new UserTeam();
$userTeam->setUser($user);
$userTeam->setTeam($lastTeam);
$userTeam->setRoleUserTeam($admin);
$user->setUserTeam($userTeam);

//persist the user
$manager->persist($user);
$manager->flush();
}
}
If you want to use events I would suggest use Doctrine events. You can use prePersist event on user entity to achieve same result. Doctrine Events

I solved my problem, I needed a cascade persist in my entities. Here, if it can hepl some people :
I had this in the Team entity
public function __construct()
{
$this->id = Team::class;
$this->userTeams = new ArrayCollection();
$this->categories = new ArrayCollection();
}
public function userTeam()
{
$newUserTeam = new UserTeam();
$newUserTeam->setTeam($this);
$this->userTeams->add($newUserTeam);
}
UserTeam entity, I had to add cascade={"persist"} in the relation ManyToOne:
class UserTeam
{
/**
* #ORM\Id
* #ORM\GeneratedValue
* #ORM\Column(type="integer")
*/
private $id;
/**
* #ORM\ManyToOne(targetEntity=Team::class, inversedBy="userTeams", cascade={"persist"})
* #ORM\JoinColumn(nullable=false)
* #Groups({"users_read", "userTeam_read"})
*/
private $team;
And the TeamByUserSubscriber that I modified :
<?php
namespace App\Events;
use ApiPlatform\Core\EventListener\EventPriorities;
use App\Entity\Team;
use App\Entity\UserTeam;
use App\Repository\RoleUserTeamRepository;
use App\Repository\TeamRepository;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpKernel\Event\ViewEvent;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\Security\Core\Security;
class TeamByUserSubscriber implements EventSubscriberInterface
{
private $security;
private $repository;
private $entityManager;
public function __construct(Security $security, RoleUserTeamRepository $repository, EntityManagerInterface $entityManager)
{
$this->security = $security;
$this->repository = $repository;
$this->entityManager = $entityManager;
}
public static function getSubscribedEvents()
{
return[
KernelEvents::VIEW => ['setUserForTeam', EventPriorities::PRE_VALIDATE],
];
}
public function setUserForTeam(ViewEvent $event)
{
$team = $event->getControllerResult();
$method = $event->getRequest()->getMethod();
if($team instanceof Team && $method === 'POST')
{
//get the connected User
$user = $this->security->getUser();
//put the current User to the team we are creating (as the creator of the team)
$team->setUser($user);
//get the Admin role from the RoleUserTeam entity
$admin = $this->repository->findOneByRoleAdmin('Admin');
//create a new instance of UserTeam with the connected User, the Team we are creating and the role
$userTeam = new UserTeam();
$userTeam->setUser($user);
$userTeam->setTeam($team);
$userTeam->setRoleUserTeam($admin);
$manager = $this->entityManager;
$manager->persist($userTeam);
$manager->flush();
}
}
