Set an entity as default [symfony2] - php

Question

I have a form where a user can upload a picture once the picture is upload it's also persist as true. I would like only the latest picture upload to be set as default (true) and the other picture of that particular user_id are set to true to be persist as false. I don't want a user to have many pictures as default.
This is what I have done:
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));
}

Set defaultPicture to false for all user avatars before creating new one.
if ($form->isSubmitted() && $form->isValid()) {
foreach ($this->container->get('security.token_storage')->getToken()->getUser()->getAvatar() as $avatar) {
$avatar->setDefaultPicture(false);
}
...
}
