实体框架-如何创建编辑/更新表单

Question

我尝试在Symfony中编辑表单

public function editAction()
{
  $id      = 5;
  $em      = $this->getDoctrine()->getEntityManager();
  $request = $this->get('request');
  $entity  = $em->getRepository('SurgeryPatientBundle:Patients')->find($id);
  $form    = $this->createForm(new SurgeryPatientBundleFormPatientsType(), $entity);
  $form->bindRequest($request);
  return $this->render('SurgeryPatientBundle:Patient:newpatient.html.twig',array('form'=>$form->createView()));
  if($form->isValid())
  {
    //do someting
  }
  else
  {
    //do something
  }
} 

我仍然得到没有数据的空表单，变量$entity是isset。我确实插入了表单，但我无法处理编辑动作。我不想用终端和php app/console创建表单因为我想知道怎么做

假设您正在使用symfony 2.0。x :

你不应该在发送数据给视图之前绑定你的请求，也不应该在测试提交的数据之前渲染视图(我猜你给我们看测试代码)

public function editAction()
{
    $id      = 5;
    $em      = $this->getDoctrine()->getEntityManager();
    $request = $this->get('request');
    $entity  = $em->getRepository('SurgeryPatientBundle:Patients')->find($id);
    $form    = $this->createForm(new SurgeryPatientBundleFormPatientsType(), $entity);
    if ($request->getMethod() == 'POST') {
        $form->bindRequest($request);
        if ($form->isValid()) {
            return $this->redirect($this->generateUrl('task_success'));
        }
    }
    return $this->render('SurgeryPatientBundle:Patient:newpatient.html.twig',array('form'=>$form->createView()));
}
