【问题描述】：
在控制器的 editAction 方法中，我尝试在类表继承中编辑现有实体。
但是表单提交后我得到错误：
既不是属性“id”也不是其中一种方法 “addId()”/“removeId()”、“setId()”、“id()”、“__set()”或“__call()” 在“AdBundle\Entity\AdFlat”类中存在并具有公共访问权限。
为什么 AdFlat 实体不是 AdBase 实体的扩展？
基础实体：
<?php

在控制器中：

if (!$adId) {
return $this->renderError('Unknown Ad');

}
$reflection = new \ReflectionClass($adEntity);
$adForm = $this->getForm($reflection->getShortName());
$form = $this->createForm($adForm, $adEntity);
$form->handleRequest($request);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($adEntity);
$em->flush();
return $this->redirectToRoute('ad_bundle_ad_view', array(
'id' => $adEntity->getId()
));
}
return $this->render('AdBundle:Ad:edit-ad-flat.html.twig', array(
'form' => $form->createView()
));
}
private function renderError($message = '')
{
return $this->render('::error.html.twig', array(
'error' => $message
));
}
private function getEntity($className)
{
$entityName = 'AdBundle\Entity\\' . $className;
return new $entityName();
}
private function getForm($className)
{
$formName = 'AdBundle\Form\Type\\' . $className . 'Type';
return new $formName();
}
