【问题描述】：
我创建一个新对象并将其绑定到一个表单。用户填写表格并转到预览页面。我将用户响应存储在会话中。
当用户返回编辑表单时，当我尝试从会话中重新加载对象时，问题就出现了。我明白了：
错误：必须管理传递给选择字段的实体。
有人知道我哪里可能出错了吗？这是控制器的代码。
public function previewdealAction(Request $request){
$session = $this->getRequest()->getSession();
$coupon = $session->get('coupon');
$form = $this->createForm(new CouponType(), $coupon);
if ($request->getMethod() == 'POST') {
//bind the posted form values
$form->bindRequest($request);
//once a valid form is submitted ...
if ($form->isValid()){
//Proceed to Previewing deal
$file = $coupon->getImage();
$file->upload();
$session->set('coupon', $coupon);
$repository = $this->getDoctrine()
->getRepository('FrontendUserBundle:Coupon');
$coupons = $repository->findAll();
return $this->render('FrontendHomeBundle:Merchant:dealpreview.html.twig', array('coupon'=>$coupon, 'coupons'=>$coupons));
}
}
}
public function builddealAction(Request $request){
$em = $this->get('doctrine')->getEntityManager();
$user = $this->container->get('security.context')->getToken()->getUser();
//check for a coupon session variable
$session = $this->getRequest()->getSession();
$coupon = $session->get('coupon');
//If coupon is not set
if($coupon == NULL){
$coupon = new Coupon();
$date = new \DateTime(date("Y-m-d H:i:s"));
$coupon->setStartdate($date);
$coupon->setPosterid($user);
$session->set('coupon', $coupon);
}
$form = $this->createForm(new CouponType(), $coupon);
return $this->render('FrontendHomeBundle:Merchant:builddeal.html.twig', array(
'form' => $form->createView(),
));
}

这里是优惠券类型类
【问题讨论】：
-
你能添加你的 CouponType 类吗？
-
优惠券和分类有什么关系？
-
max per 只是优惠券实体中的一个整数字段。
-
主要的违规字段似乎是城市和类别。但这很奇怪，如果我从会话中加载优惠券实体，它只会引发错误，而不是如果它是新的 Coupon();
-
你找到解决方案了吗？我正在使用
FormBuilder::setData()遇到类似的问题，我已从已发布的表单中提取并存储在会话中。
