symfony - One form with all row of one entity

Question

I have an entity Film with 3 string fields. I've made a form to create Entities A without problems, it woks fine.

Now I would like to make a Table with each films in my entity (one by row) and to be able to change the fields I want to, and save in one time all the changes.

I've try with the cook book "How to Embed a Collection of Forms" but it doesn't correspond to my problem :c/

Here is some sample code to explain what I'm trying to do but who doesn't work :

Entity Film

 class Film
 {
     /**
     * @var int
     *
     * @ORMColumn(name="id", type="integer")
     * @ORMId
     * @ORMGeneratedValue(strategy="AUTO")
     */
     private $id;

/**
 * @ORMColumn(type="string",nullable=false)
 */
private $name;

/**
 *
 * @ORMColumn(type="string")
 */
private $style;

/**
 * @ORMColumn(type="string")
 */
private $director;

/**
 * @ORMColumn(type="string")
 */
private $actor;

Controller Film

 public function updateAction(Request $request)
 {

    $films = $this->getDoctrine()
                  ->getRepository('LfayBundle:FilmFilm');
    $films_all = $films->findAll();

    foreach ($films_all as $film) {
        $form = $this->createForm(FilmType::class, $film);
        $forms[] = $form->createView();
    }

    $form_film->handleRequest($request);
    if ($form_film->isSubmitted() && $form_film->isValid()) {

        $em = $this->getDoctrine()->getManager();
        $em->persist($films_all);
        $em->flush();

        return $this->redirectToRoute('film_update');
    }

    return $this->render(
      'film/film_update.html.twig',
      array(
        'form_film' => $forms,
      )
    );
}

Type Film

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('name', TextType::class)
        ->add('style', TextType::class)
        ->add('director', TextType::class)
        ->add('actor', TextType::class)
    ;
}

/**
 * @param OptionsResolver $resolver
 */
public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'LfayBundleEntityFilmFilm'
    ));
}

I've found !!!!

Here is my solution if someone need to solve the same problem.

FilmController :

   /**
     * @Route("/film/update", name="film_update")
     */
    public function updateAction(Request $request)
    {

        $films = array('films' => $this->getDoctrine()->getRepository('LfayBundle:FilmFilm')->findAll()) ;
        $forms = $this->createForm(FilmContainerType::class, $films);

        $forms->handleRequest($request);
        if ($forms->isSubmitted() && $forms->isValid()) {

            $em = $this->getDoctrine()->getManager();
            //$em->persist($films_all);
            $em->flush();

            return $this->redirectToRoute('film_update');
        }

        return $this->render(
          'film/film_update.html.twig',
          array(
            'forms' => $forms->createView(),
          )
        );
    }

FilmContainerType :

class FilmContainerType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
          ->add('films', CollectionType::class, array(
          'entry_type' => FilmType::class));
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
          'data_class' => null
        ));
    }

    public function getName()
    {
        return 'xxxx_bundle_film_container_type';
    }
}

FilmType :

class FilmType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
          ->add('style', TextType::class)
          ->add('director', TextType::class)
          ->add('actor', TextType::class)
        ;
    }

    /**
     * @param OptionsResolver $resolver
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'xxxxBundleEntityFilmFilm'
        ));
    }
}

                                </tr>
                            {% endfor %}
                             </tbody>
                        </table>
                         <button type="submit" class="btn btn-primary btn-lg btn-block">Modifier</button>
                         {{ form_end(forms) }}
