Question

我无法获取实体的编辑表单字段以将实体值放在每个字段中。在我的控制器中，我能够搜索首先通过其第一个实体标识符搜索该特定行。在这种情况下，它是从表单中搜索DA编号（dano），该编号转到显示该行的操作。该行将有一个编辑操作，该操作将转到编辑页面，其中表单将具有显示要编辑的实体的输入字段。但是，在尝试将它们全部插入时，我不断收到此错误消息：

Catchable Fatal Error: Argument 1 passed to 
...Bundle\Controller\EditController::createEditForm() must be an instance of
...\Bundle\Entity\SumitomoMain, array given, called in 
...\Bundle\Controller\EditController.php on line 83 and defined in 
...\Bundle\Controller\EditController.php line 99

我绝对不知道从哪里开始检查问题。

以下是我的控制器中的操作：

/**
 * @return \Symfony\Component\HttpFoundation\Response
 * @Route("/", name="edit_home")
 * @Template()
 * @Method("GET")
 */
public function indexAction(Request $request)
{
    $form = $this->createDAForm();
    $form->handleRequest($request);

    if($form->isValid()) {

        return $this->redirect($this->generateUrl('edit_showda', array(
                'dano' => $form->get('dano')->getData()
                )));
    }

    return array(
            'searchdaform'      => $form->createView(),
        );
}

/**
 * @param Request $request
 * @return Response
 * @Route("/{dano}", name="edit_showda")
 * @Method("GET")

public function showDAAction($dano) {

    $getda = $this->getDoctrine()
        ->getRepository('CIRBundle:SumitomoMain')
        ->findByDano($dano);
    if (!$getda) {
        throw $this->createNotFoundException('Unable to find DA #');
    }

    return $this->render('CIRBundle:Edit:showda.html.twig', array(
            'dano' => $getda
        ));
}

/**
 * @param Request $request
 * @param $dano
 * @Route("/{dano}/edit", name="edit_editeda")
 * @Method("GET")
 * @Template()
 */
public function editDAAction($dano) {
    $em = $this->getDoctrine()->getManager();

    $entity = $em->getRepository('CIRBundle:SumitomoMain')->findByDano($dano);

    if (!$entity) {
        throw $this->createNotFoundException('Unable to find DA');
    }

    $editform = $this->createEditForm($entity);

    return array(
        'entity'      => $entity,
        'editform'    => $editform->createView()
     );

}

/**

 * @param $dano
 * @return array|\Symfony\Component\HttpFoundation\RedirectResponse
 * @throws \Symfony\Component\HttpKernel\Exception\NotFoundHttpException

 */
public function updateDAAction(Request $request, $dano) {
    $em = $this->getDoctrine()->getManager();

    $entity = $em->getRepository('CIRBundle:SumitomoMain')->find($dano);

    if (!$entity) {
        throw $this->createNotFoundException('Unable to find SumitomoMain entity.');
    }

    $editForm = $this->createEditForm($entity);
    $editForm->handleRequest($request);

    if ($editForm->isValid()) {
        $em->flush();

        return $this->redirect($this->generateUrl('edit_editeda', array('dano' => $dano)));
    }

    return array(
        'entity'      => $entity,
        'edit_form'   => $editForm->createView(),
    );
}

/**
 * Creates a form to edit a SumitomoMain entity.
 *
 * @param SumitomoMain $entity The entity
 *
 * @return \Symfony\Component\Form\Form The form
 */
private function createEditForm(SumitomoMain $entity)
{
    $form = $this->createForm(new SumitomoMainType(), $entity, array(
            'action' => $this->generateUrl('edit_update', array('dano' => $entity->getDano())),
            'method' => 'PUT',
        ));

    $form->add('submit', 'submit', array('label' => 'Update'));

    return $form;
}

  public function createDAForm() {
    $form = $this->createFormBuilder()
        ->setMethod('GET')
        ->add('dano', 'text', array(
                'label' => 'DA #',
            ))
        ->add('submit','submit')
        ->getForm();

    return $form;
}

我已经检查了我的表单类型，看起来一切都很好：

class SumitomoMainType extends AbstractType
{
 /**
 * @param FormBuilderInterface $builder
 * @param array $options
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('dano','text', array(
                'label' => 'DA'
            ))
        ->add('partno','text', array(
                'label' => 'Part'
            ))
        ->add('batchno','text', array(
                'label' => 'Batch'
            ))
        ->add('indate','date', array(
                'label' => 'Date',
                'widget' => 'single_text'
            ))
    ;
}

    $resolver->setDefaults(array(

任何帮助将不胜感激！

Answer 1

$em->getRepository('CIRBundle:SumitomoMain')->findByDano($dano)返回匹配项的数组。您将结果传递给createEditForm，findOneByDano只需要一个实体而不是数组。

您必须使用{{1}}代替，才能获得一个结果。

Symfony：使用表单编辑实体
