我对Symfony有问题，我正在尝试动态嵌套表单
有一个订单，每个订单有多张票证
当我坚持表格时，我有一张桌子，上面有票证和订单，但是没有commands_id，所以没有链接
这是我的代码：

还有控制器
namespace CoreBundle\Controller;
use CoreBundle\Entity\Commandes;
use CoreBundle\Form\CommandesType;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
class DefaultController extends Controller
{
public function indexAction(Request $request)
{
$commandes = new Commandes();
$form = $this->createForm(CommandesType::class, $commandes);
if ($request->isMethod('POST') && $form->handleRequest($request)->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($commandes);
$em->flush();
return $this->render('@Core/Default/index.html.twig', array(
'form' => $form->createView(),
));
}
}
我已经进行了几次搜索，我认为问题出在控制器或实体上，但是找不到！
谢谢您的帮助
答案 0 :(得分：0)
您的Commandes实体无效。
尝试一下：
/**
* Add billet
*
* @param \CoreBundle\Entity\Billets $billet
*
* @return Commandes
*/
public function addBillet(\CoreBundle\Entity\Billets $billet)
{
$billet->setCommandes($this);
$this->billets->add($billet);
return $this;
}
