Установить сущность по умолчанию [symfony2]

Question

У меня есть форма, где user может загрузить изображение после загрузки изображения, оно также сохраняется как true. Я хотел бы, чтобы только последняя загрузка изображения была установлена ​​по умолчанию (true), а другая картинка этого user_id установлена ​​в значение true, чтобы она сохранялась как false. Я не хочу, чтобы у пользователя было много фотографий по умолчанию.

Это то, что я сделал:

public function avatarUserAction(Request $request) 
{ 
    $em = $this->getDoctrine()->getManager(); 
    $user = $this->container->get('security.token_storage')->getToken()->getUser(); 
    $entity = new Avatar(); 
    $form = $this->createForm(new AvatarType(),$entity); 
    if ($this->get('request')->getMethod() == 'POST') { 
     $form->handleRequest($request); 
     if ($form->isSubmitted() && $form->isValid()) { 

      $entity->setCreatedAt(new \DateTime()); 
      $entity->setDefaultPicture(true); 
      $entity->setUser($this->container->get('security.token_storage')->getToken()->getUser()); 
      $em->persist($entity); 
      $em->flush(); 
     } 
     return $this->redirect($this->generateUrl('avatarUser')); 
    } 

    return $this->render('ApplicationSonataUserBundle:Profile:avatar.html.twig', array('user' => $user,'entity' => $entity, 
     'form' => $form->createView())); 
} 

.

public function avatarUserAllAction() 
{ 
    $em = $this->getDoctrine()->getManager(); 
    $user = $this->container->get('security.token_storage')->getToken()->getUser(); 
    $entity = $em->getRepository('ApplicationSonataUserBundle:Avatar')->byAvatar($user); 
    return $this->render('ApplicationSonataUserBundle:Profile:avatar_all_image.html.twig', array('user' => $user,'entity' => $entity)); 
} 

routing.yml

avatarUser: 
    pattern: /profile/picture 
    defaults: { _controller: FLYBookingsBundle:Post:avatarUser } 

avatarUserAll: 
    pattern: /profile/picture 
    defaults: { _controller: FLYBookingsBundle:Post:avatarUserAll }

Answer 1

Установите defaultPicture в false для всех пользовательских аватаров перед созданием нового.

if ($form->isSubmitted() && $form->isValid()) { 
    foreach ($this->container->get('security.token_storage')->getToken()->getUser()->getAvatar() as $avatar) { 
     $avatar->setDefaultPicture(false); 
    } 

    ... 
}
