断开两个ManyToMany实体之间的链接而不删除数据

Question

我有一个实体“组织”和一个实体“用户”都设置为ManyToMany，组织（组织）的领导者可以向其组织添加新用户，如果没有，将在数据库中创建用户已存在或链接到它（如果已存在）。

但是当领导者想要从组织中删除用户时，该用户将从数据库中删除，我不希望这种情况发生，因为用户可以不属于一个组织或属于多个组织而存在。

#[ORM\ManyToMany(targetEntity: User::class, mappedBy: 'organizations', cascade: ['persist'])]
    private Collection $users;

    /**
     * @return Collection<int, User>
     */
    public function getUsers(): Collection
    {
        return $this->users;
    }

    public function addUser(User $user): static
    {
        if (!$this->users->contains($user)) {
            $this->users->add($user);
            $user->addOrganization($this);
        }

        return $this;
    }

    public function removeUser(User $user): static
    {
        if ($this->users->removeElement($user)) {
            $user->removeOrganization($this);
        }

        return $this;
    }

#[ORM\ManyToMany(targetEntity: Organizations::class, inversedBy: 'users')]
    private Collection $organizations;


    /**
     * @return Collection<int, organizations>
     */
    public function getOrganizations(): Collection
    {
        return $this->organizations;
    }

    public function addOrganization(Organizations $organization): static
    {
        if (!$this->organizations->contains($organization)) {
            $this->organizations->add($organization);
        }

        return $this;
    }

    public function removeOrganization(Organizations $organization): static
    {
        $this->organizations->removeElement($organization);

        return $this;
    }

我尝试使用 Doctrine 生成的不同函数，但我尝试的所有最终结果都是从数据库中删除用户。

这是我当前的代码：

class OrganizationUserRemovingProcessor implements ProcessorInterface
{
    public function __construct(private OrganizationsRepository $organizationsRepository, private UserRepository $userRepository, private EntityManagerInterface $entityManager)
    {
        // dd('Bonjour!');
    }
    public function process(mixed $data, Operation $operation, array $uriVariables = [], array $context = []): mixed
    {

        $organization = $this->organizationsRepository->findOneBy(['id' => $uriVariables['id']]);

        if ($organization) {
            $user = $this->userRepository->findOneBy(['id' => $uriVariables['userId']]);

            if ($user) {
                $user->removeOrganization($organization);

                $this->entityManager->flush();

                return $organization;
            }
        }

        return null;
    }
}

您是否尝试在两个实体中都这样做？

<?php
class Organization
{
    public function removeUser(User $user): static
    {
        if ($this->users->contains($user)) {
            $this->users->removeElement($user);
            $user->removeOrganisation($this);
        }
    }
}

class User
{
    public function removeOrganization(Organizations $organization): static
    {
        if ($this->organisations->contains($organisation)) {
            $this->organisations->removeElement($organisation);
            $organisation->removeUser($this);
        }
    }
}
