我正在使用 symfony 2.7 表单组件来更新名为TapsAlert的实体。
问题是提交表单后实体没有更新。
我不知道出了什么问题。感谢您的建议,这是部分代码:

public function editarRegistroAction(Request $request, $id){

    $em = $this->getDoctrine()->getManager();
    $altd = $em->getRepository('ModeloBundle:TapsAlert')->find($id);


    $altd->setAsunto($altd->getAsunto());
    $altd->setGls($altd->getGls());
    $altd->setDestinatario($altd->getDestinatario());
    $altd->setPrts($altd->getPrts());
    $altd->setTags($altd->getTags());
    $altd->setValor($altd->getValor());


    $form = $this->createFormBuilder($altd)
        ->add('Asunto', 'text')
        ->add('gls', 'text')
        ->add('destinatario', 'text')
        //->add('dias', 'number')
        ->add('prts', 'text')
        ->add('Tags', 'text')
        ->add('valor', 'text')
        ->add('save', 'submit', array('label' => 'Guardar Cambios'))
        ->getForm();



        //$form->handleRequest($request);

        if ($form->isSubmitted() && $form->isValid()) {

            //$edAlert = $form->getData();
            $em = $this->getDoctrine()->getManager();
            //$em->persist($altd);
            $em->flush();

            return $this->redirect('http://192.168.1.128/');

        }



    return $this->render('MotoBundle:Default:edit.html.twig', array('form' => $form->createView()));

}

1 个答案:

答案 0 :(得分:2)

首先:这部分代码没有用。应该将其删除:

$altd->setAsunto($altd->getAsunto());
$altd->setGls($altd->getGls());
$altd->setDestinatario($altd->getDestinatario());
$altd->setPrts($altd->getPrts());
$altd->setTags($altd->getTags());
$altd->setValor($altd->getValor());

第二:您未处理您的请求:

  public function editarRegistroAction(Request $request, $id){
        $em = $this->getDoctrine()->getManager();
        $altd = $em->getRepository('ModeloBundle:TapsAlert')->find($id);

        $form = $this->createFormBuilder($altd)
            ->add('Asunto', 'text')
            ->add('gls', 'text')
            ->add('destinatario', 'text')
            //->add('dias', 'number')
            ->add('prts', 'text')
            ->add('Tags', 'text')
            ->add('valor', 'text')
            ->add('save', 'submit', array('label' => 'Guardar Cambios'))
            ->getForm();

            $form->handleRequest($request); //uncomment this line
            if ($form->isSubmitted() && $form->isValid()) {
                $em->flush();

                return $this->redirect('http://192.168.1.128/'); // This url should an be an external url
            }

        return $this->render('MotoBundle:Default:edit.html.twig', array('form' => $form->createView()));
    }

第三步:我相信您可以使用paramConvertor来改进代码:

  public function editarRegistroAction(Request $request, TapsAlert $tapsAlert){

        $form = $this->createFormBuilder($tapsAlert)
            ->add('Asunto', 'text')
            ->add('gls', 'text')
            ->add('destinatario', 'text')
            //->add('dias', 'number')
            ->add('prts', 'text')
            ->add('Tags', 'text')
            ->add('valor', 'text')
            ->add('save', 'submit', array('label' => 'Guardar Cambios'))
            ->getForm();

            $form->handleRequest($request);
            if ($form->isSubmitted() && $form->isValid()) {
                $this->getDoctrine()->getManager()->flush();

                return $this->redirect('http://192.168.1.128/'); // This url should an be an external url
            }

        return $this->render('MotoBundle:Default:edit.html.twig', array('form' => $form->createView()));
    }

这是一种更好的做法,也可以在单独的类中构建表单,有关更多详细信息,请查看官方文档https://symfony.com/doc/current/forms.html#creating-form-classes
