Unlink role - BjyAuthorize Doctirne

Question

BjyAuthorize modifies the User entity and provides an addRole() method. This accepts a role object and populates the user_role_linker_table

How is it possible to remove a role once it is added to a user?

The associations are set in User:

/**
     * @var \Doctrine\Common\Collections\Collection
     * @ORM\ManyToMany(targetEntity="Application\Entity\Role")
     * @ORM\JoinTable(name="user_role_linker",
     *      joinColumns={@ORM\JoinColumn(name="user_id", referencedColumnName="id")},
     *      inverseJoinColumns={@ORM\JoinColumn(name="role_id", referencedColumnName="id")}
     * )
     */
    protected $roles;

Answer 1

After hours of struggle I came up with the following solution:

$userDetails = $em->getRepository('Application\Entity\UserDetails')->findOneBy(['id' => $data['user-details-id']]);
$user = $userDetails->getUser();

$roleRepo = $em->getRepository('Application\Entity\Role');
$roleResult = $roleRepo->findOneBy(['id' => $id]); //$id is the role to delete
$user->removeRole($roleResult);

$em->merge($user);
$em->flush();

In the User entity I added the method:

    public function removeRole($role)
    {
        return $this->roles->removeElement($role);
    }

Not sure if this is the approach that the authors of BjyAuthorize intended but it works for me...

Looks good to me. Just want to add that you should first check if the roles contains that role you want to delete.

Such as this:

public function removeRole($role)
{
    if (!$this->roles->contains($role))
    {
         return;
    }
    $this->roles->removeElement($role);
}
