Symfony：使用表单编辑实体

Question

我在获取实体的编辑表单字段以将实体值放置在每个字段中时遇到麻烦。 在我的控制器中，我能够通过第一个实体标识符搜索到该特定行。 在这种情况下，这是从表单中搜索DA编号（dano），然后转到显示该行的操作。 该行将具有一个编辑操作，该操作将转到一个编辑页面，在该页面上表单将具有显示要编辑实体的输入字段。 但是，除了尝试将它们全部插入时，我总是收到此错误消息：

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 Request $request
 * @param $dano
 * @return array|\Symfony\Component\HttpFoundation\RedirectResponse
 * @throws \Symfony\Component\HttpKernel\Exception\NotFoundHttpException
 * @Route("/{dano}", name="edit_update")
 * @Method("PUT")
 * @Template("CIRBundle:Edit:editda.html.twig")
 */
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;
}

我检查了我的表单类型，一切看起来都很好：

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(
        'data_class' => 'CIR\Bundle\Entity\SumitomoMain'

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。 您将该结果传递给createEditForm ，它只需要一个实体而不是一个数组。

您必须改用findOneByDano才能获得一个结果。
