Why is the record in the database not updated?

Question

symfony

I can not understand why the data in the database from the form is not updated.

$em = $this->getDoctrine()->getManager();
$vote = $em->getRepository('ACVoteVotesBundle:Votes')->findById($id);
$form = $this->createForm(new addVoteInfoType(), $vote);
$form->handleRequest($request);
$em->flush();

What's wrong?

Answer 1

The findBy* method returns an array.
Use findOneBy* or find($id) in the current case.

Answer 2

You forgot to do before flush.
$em->persist($vote);
