How to assign roles on successful registration?

Question

I'm using fos user bundle and pugx multi user bundle. I've read all the documentation and I'm new to Symfony. In the pugx multi user bundle there's a sample on every point but one: sucessful registration.

• Samples of overriding controllers for generating forms => ok
• Samples of overriding templates for generating forms => ok
• Samples of overriding successful registration sample => nothing.

Here's my code:

class RegistrationController extends BaseController
{
    public function registerAction(Request $request)
    {   
        $response = parent::registerAction($request);
        return $response;
    }   

    public function registerTeacherAction()
    {   
        return $this->container
            ->get('pugx_multi_user.registration_manager')
            ->register('MyBundle\Entity\PersonTeacher');
    }   

    public function registerStudentAction()
    {   
        return $this->container
            ->get('pugx_multi_user.registration_manager')
            ->register('MyBundle\Entity\PersonStudent');
    }   
}

The problem is with ->get('pugx_multi_user.registration_manager') which returns a manager. In the fos user overring controllers help, they get either a form or a form.handler. I'm having hard times to "link" those with the pugx_multi_user manager.

What code should I put in the registerTeacherAction() to set roles for teacher, and in registerStudentAction() to set roles for student on a successful registration?

Solution 1 (Doctrine Listener/Subscriber)

---

You can easily add a doctrine prePersist listener/subscriber that adds the roles/groups to your entities depending on their type before persisting.

The listener

namespace Acme\YourBundle\EventListener;

use Doctrine\ORM\Event\LifecycleEventArgs;
use Acme\YourBundle\Entity\Student;

class RoleListener
{
    public function prePersist(LifecycleEventArgs $args)
    {
        $entity = $args->getEntity();
        $entityManager = $args->getEntityManager();

        // check for students, teachers, whatever ...
        if ($entity instanceof Student) {
            $entity->addRole('ROLE_WHATEVER');
            // or
            $entity->addGroup('students');
            // ...
        }

       // ... 
    }
}

The service configuration

# app/config/config.yml or load inside a bundle extension
services:
    your.role_listener:
        class: Acme\YourBundle\EventListener\RoleListener
        tags:
            - { name: doctrine.event_listener, event: prePersist }

Solution 2 (Doctrine LifeCycle Callbacks):

---

Using lifecycle callbacks you can integrate the role-/group-operations directly into your entity.

/**
 * @ORM\Entity()
 * @ORM\HasLifecycleCallbacks()
 */
class Student
{
    /**
     * @ORM\PrePersist
     */
    public function setCreatedAtValue()
    {
        $this->addRole('ROLE_WHATEVER');
        $this->addGroup('students');
    }

Solution 3 (Event Dispatcher):

---

Register an event listener/subscriber for the "fos_user.registration.success" event.
