我为我的问题对象制作了一个CRUD。我测试后发生错误。
似乎getId()返回某种空字符串。
自动生成的CRUD的默认行为是在成功创建实体后将用户重定向到视图页面。但在这种情况下,它会返回错误
" 参数" id"路线" question_show"必须匹配" [^ /] ++" (""给出)生成相应的网址。"
这是我的控制器代码:
/**
* Creates a new Question entity.
*
* @Route("/ask", name="question_create")
* @Method("POST")
* @Template("VerySoftAskMeBundle:Question:ask.html.twig")
*/
public function createAction(Request $request) {
$entity = new Question();
$form = $this->createCreateForm($entity);
$form->handleRequest($request);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($entity);
$em->flush();
return $this->redirect($this->generateUrl('question_show', array('id' => $entity->getId())));
}
return array(
'entity' => $entity,
'form' => $form->createView(),
);
}
以下是视图操作:
/**
* Finds and displays a Question entity.
*
* @Route("/{id}", name="question_show")
* @Method("GET")
* @Template()
*/
public function showAction($id) {
$em = $this->getDoctrine()->getManager();
$entity = $em->getRepository('VerySoftAskMeBundle:Question')->find($id);
if (!$entity) {
throw $this->createNotFoundException('Unable to find Question entity.');
}
$deleteForm = $this->createDeleteForm($id);
return array(
'entity' => $entity,
'delete_form' => $deleteForm->createView(),
);
}
/**
* Creates a form to create a Question entity.
*
* @param Question $entity The entity
*
* @return Form The form
*/
private function createCreateForm(Question $entity) {
$form = $this->createForm(new QuestionType(), $entity, array(
'action' => $this->generateUrl('question_create'),
'method' => 'POST',
'em' => $this->getDoctrine()->getEntityManager()
));
$form->add('submit', 'submit', array('label' => 'Ask'));
return $form;
}
我该如何解决这个问题?

您的实体似乎未持久存储在数据库中。你能检查一下吗?
此外,您的代码中似乎是一个拼写错误" $ form = $ this-> createCreateForm($ entity);",而不是$ this-> createForm
否则我使用下面的代码(与你的代码相似)没有问题
/**
* @Route("/new", name="item_new")
* @Template()
*
* @return array
*/
public function newAction(Request $request)
{
$em = $this->get('doctrine.orm.entity_manager');
$item = new Item();
$form = $this->createForm(new ItemType(), $item, array(
'action' => $this->generateUrl('item_new'),
'method' => 'POST',
));
$form->handleRequest($request);
if ($form->isValid()) {
$em->persist($item);
$em->flush();
return $this->redirect($this->generateUrl('item_list'));
}
return array('form' => $form->createView());
}

修正了它。我继承了一个名为Post
的类,它有一个$id
变量。事实证明我忘记删除$id
类中的Question
变量,这就是为什么Symfony对要返回的id感到困惑的原因。
