Bind an object to a Symfony form - symfony

Question

I have a entity with some data prefilled, and I want to display them on the form : here state would be ACTIVE and customerId = 1;
// Form file (ben.file.create)
protected function buildForm()
{
$this->formBuilder->add('name', 'text', ['label'=>'Nom du patient'])
->add('customerId', 'integer')
->add('state', 'choice', ['choices'=>['ACTIVE'=>'ACTIVE',
'DONE'=>'DONE', 'CANCELLED'=>'CANCELLED']]);
}
// in the controller
public function index()
{
$form = $this->createForm("ben-file-create");
$file = new BenFile();
$file->setCustomerId(1);
$file->setState('ACTIVE');
$form->getForm()->submit($file); // <--- Here the glue problem
return $this->render('create-file', array());
}
It looks like submit is not the right bind function. I would expect that the form is pre-filled accordingly, and after the POST request, I have an updated BenFile entity.

You can do easily in createForm method :
// in the controller
public function index(Request $request)
{
$file = new BenFile();
$file->setCustomerId(1);
$file->setState('ACTIVE');
$form = $this->createForm("ben-file-create", $file);
// handle submit
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
// flush entity
$fileNew = $form->getData();
$entityManager = $this->getDoctrine()->getManager();
$entityManager->persist($fileNew );
$entityManager->flush();
}
return $this->render('create-file', array());
}
