Symfony 2 - 两级嵌套表单

Question

我是Symfony 2的新手，我不得不说我仍然没有得到关于它的一切，这就是我想要实现的目标。 在“测验”页面上，管理员添加一个新测验，因为他这样做，他可以动态添加新问题，尽可能多地使用jQuery和嵌套表单“问题”。然后创建第二个级别，对于他创建的每个问题，他可以创建答案，并选择一个或多个作为正确的答案，基本上让我有多项选择问卷。

我设法让所有工作都为数据持久性T_T

 ErrorHandler ->handle ('2', 'spl_object_hash() expects parameter 1 to be object, array given', 
'C:\wamp\www\Symfony\vendor\doctrine\orm\lib\Doctrine\ORM\UnitOfWork.php', '1367', array(**'entity'** => array('qContent' => 'Test QuestionContent', 'qType' => '2', 'answer' => array(array('aContent' => 'Test AswerContent', 'isRight' => '1'))), 'assume' => '2'))

我理解Doctrine想要一个实体而不是一个数组，但是如何在不必完全重建数据持久化过程的情况下保持我的表单返回的内容？！

好的，你已经等了足够长的时间，这是代码^^

AddQuiz Controler：

 public function addQuizAction($lesson)
    {
        $new_quiz = new Quiz;

        //Find the lesson entity
        $repository = $this ->getDoctrine()
                             ->getManager()
                             ->getRepository('InkyCourseBundle:Lesson');
        $lessonRep = $repository->findOneBy(array('id' => $lesson));

        // Create Quiz


        if ($this->getUser()) { $new_quiz->setUser($this->getUser());}
        if ($lessonRep) { $new_quiz->setLesson($lessonRep);}

        $form = $this->createForm(new QuizType(), $new_quiz);
        $request = $this->getRequest();
        if ($request->getMethod() == 'POST')
        {
            $form->bind($request);
            if ($form->isValid()) 
            {
                $em = $this->getDoctrine()->getManager();
                $em->persist($new_quiz);
                $em->flush();

                $this->get('session')->getFlashBag()->add('info', 'Quiz bien ajouté');
                return $this->redirect($this->generateUrl('quiz_edit', array('id' => $new_quiz->getId(),'lesson' => $lesson)));
            }
        }
