具有多个实体的Symfony2表单在提交时变慢

Question

我有一个名为Materials的实体，有8个关联实体（带连接表）。 当我提交表单来更新数据库中的现有实体/记录时，最多需要24秒才能完成该过程。我读到了一些我不应该使用的地方：

$em = $this->getDoctrine()->getManager();
$form->handleRequest($request);
$data = $form->getData();
$em->persist($data);
$em->flush();

因为多个实体需要花费太长时间才能坚持，但为了提高性能，我应该使用更新查询：

Exp.
$em = $this->getDoctrine()->getManager();
$repo = $em->getRepository('ourcodeworldBundle:Posts');
$newCreatedAt = new \DateTime();

$qb = $repo->createQueryBuilder('p');
    $qb->update()
        ->set('p.createdAt', ':newCreatedAt')
        ->setParameter('newCreatedAt', $newCreatedAt); 
$qb->getQuery()->execute();

有人知道这是否正确，如果是，我是否必须手动更新每个实体？我需要很长时间才能将其写为查询，因为它有很多。

Answer 1

我发现了问题。

用于在我的控制器中$form->handleRequest($request);处失败的表单：

if ($request->getMethod() == 'POST') {
  $req = $request->request->get("material");
  $form->handleRequest($request);
  ...
}

但真正的问题是我的Material类中的Assert语句没有很好地定义。一旦我更正了handleRequest，就不再减慢表单提交过程。

这是我更新的Material类，带有固定的Assert语句：
