Попробуйте отредактировать запись в symfony (файл VichUploaderBundle)

Я пытаюсь редактировать запись в Symfony. Я могу редактировать текстовую запись, но я не могу редактировать новый файл в записи. ((Файл сохранен в хранилище, но не сохраняется в базе данных))

Как я могу это сделать в Symfony 3.4 с VichUploaderBundle 1.4 ... для вставки у меня нет проблем, я загружаю изображение в хранилище и сохраняю в базе данных .....

это мое действие редактирования

/**
 * @Route("/Article/editArticle/{id}",name = "editArticle")
 */
public function editArticleAction(Request $request, $id)
{
    $em = $this->getDoctrine()->getManager();
    $articleRepo=$em->getRepository('AdminBundle:Article');
    $articleata = $articleRepo->find($id);
    // $satelliteImage=new satelliteImage;
    $article = new Article();
    $form = $this->createForm(ArticleType::class,$article,array(
        'action' => $this->generateUrl('editArticle',array('id' => $articleata->getId())),
        'attr' => array(
            'class' => 'dropzone',
            'id'  => "my-awesome-dropzone"
        ),

        [
            'name'        => $articleata->getName(),

            'smallPic'    => $articleata->getSmallPic(),
            'largPic'     => $articleata->getLargPic(),
            'displayStatus' => $articleata->getDisplayStatus()]
    ));
   //

    if ($request->getMethod() == Request::METHOD_POST){
 $form->handleRequest($request);
        $article->setName($form->get('name')->getData());
        $article->setTitle($form->get('title')->getData());
