doctrine-orm - Symfony2 不一致的表单绑定和持久化行为，实体关联不一致

Question

我有一个属于一个或多个类别的实体，每个实体（Boom）都有许多属性或子元素（Boomelement），在这种情况下它们应该是 7。

当我尝试根据执行顺序保留实体时，我得到不同的结果：

如果我创建一个空实体，绑定请求，然后坚持：
- 生成实体
- 类别被正确分配
- 子元素被持久化，但它们没有与实体关联，具有外键的列显示为 null
如果我制作一个没有空实体的表单，则绑定请求并保持：
- 生成实体
- 该类别没有得到分配
- 子元素被持久化并与实体相关联
如果我使用空实体创建表单并分配 1 个空子元素，则绑定请求然后持久化：
- 生成实体
- 类别被分配
- 只有 1 个子元素与实体关联，其余子元素被持久化但未将列与外键关联显示为 null
如果我使用空实体创建表单并分配 7 个空子元素，则绑定请求然后持久化：
- 生成实体
- 类别被分配
- 7 个子元素与实体相关联
- 如果我动态添加更多子元素怎么办，它们将不会被关联

我认为这种行为是不一致和奇怪的，除此之外没有记录。

有没有办法正确地做到这一点？

控制器动作：

public function createAction() {
    $entityEmpty = new Boom();
    //for ($i = 0; $i <= 6; $i++) {
        $element = new Boomelement();
        $entityEmpty->addElement($element);
        //$element->setPosition($i);
    //}

    $form = $this->createForm(new BoomType(),$entityEmpty);
    $request = $this->getRequest();
    $form->bind($request);
    $entity = $form->getData();
    var_dump($entityEmpty);
    var_dump($entity);
    //exit;
    if ($form->isValid()) {
        $em = $this->getDoctrine()->getManager();
        $em->persist($entity);
        $em->flush();

        //return $this->redirect($this->generateUrl('boom_show', array('id' => $entity->getId())));
    }else{
        //var_dump($form->getErrors());
        //var_dump(get_class_methods($form));
    }

    return $this->render('BoomBackBundle:Boom:new.html.php', array(
                'entity' => $entity,
                'form' => $form->createView(),
            ));
}

当我使用空实体创建表单时，相关记录

public function createAction() {
    $entityEmpty = new Boom();
    $form = $this->createForm(new BoomType(),$entityEmpty);
    $request = $this->getRequest();
    $form->bind($request);
    if ($form->isValid()) {
        $em = $this->getDoctrine()->getManager();
        $em->persist($entityEmpty);
        $em->flush();

        return $this->redirect($this->generateUrl('boom_show', array('id' => $entity->getId())));
    }else{
        //var_dump($form->getErrors());
        //var_dump(get_class_methods($form));
    }

    return $this->render('BoomBackBundle:Boom:new.html.php', array(
                'entity' => $entity,
                'form' => $form->createView(),
            ));
}

doctrine-orm - Symfony2 不一致的表单绑定和持久化行为，实体关联不一致
