Question

当用户在edit_form上编辑数据（例如）然后单击提交按钮时，他会被重定向到页面，其中的更改应该是可见的。

public function updateAction(Request $request, $id)
{
    $em = $this->getDoctrine()->getManager();
    $entity = $em->getRepository('ClientBundle:Client')->find($id);

    $kdnr = $entity->getKdnr();

    if (!$entity) {
      throw $this->createNotFoundException($this->get('translator')->trans('client.messages.notfound'));
    }

    $deleteForm = $this->createDeleteForm($id);
    $editForm = $this->createEditForm($entity);
    $editForm->handleRequest($request);

    $entity->setKdnr($kdnr);

    if ($editForm->isValid()) {
        $em->flush();
        $this->getRequest()->getSession()->getFlashBag()->add('notice', $this->get('translator')->trans('messages.savenotice'));
        return $this->redirect($this->generateUrl('client_show', array('id' => $id)));
    }

    return $this->render('ClientBundle:Client:edit.html.twig', array(
        'entity'      => $entity,
        'edit_form'   => $editForm->createView(),
        'delete_form' => $deleteForm->createView(),
    ));
}

之后，该消息可见，但更改仅在刷新页面后可见。并且页面刷新后消息才会消失。当我离开视图并再次访问时，消息仍然存在。

是否可能在表单提交后直接显示更改并且消息仅显示一次？这是会话问题吗？
