Question

我有一个symfony表单，由于某种原因无法构建它应该构建的对象，因此当我在控制器中调用EntityManager#persist() expects parameter 1 to be an entity object, array given.时，我得到$manager->persist($form->getData());。现在我几乎确信问题来自于我的实体的构建方式，但我无法弄清楚什么是错误的。

表格

class EtatSuiviDossierType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $option)
    {
        $builder
            ->add('nom', TextType::class, array(
                'required' => true
            ))
            ->add('task', EntityType::class, array(
                'class' => 'AppBundle:Task',
                'choice_label' => function ($task)
                {
                    return $task->getName();
                }
                ,'label' => 'Tâche (Optionnelle)'
            ))
            ->add('btnAction', SubmitType::class);
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'AppBundle\Entity\Task'
        ));
    }
}

        $this->addFlash('message', $message);

我的实体是否正确构建？感谢任何能提供任何建议的人！

TL; DR

我必须从我的控制器

中初始化我的表单

$etatSuiviDossier = new EtatSuiviDossier("");
$form = $this->createForm(EtatSuiviDossierType::class, $etatSuiviDossier);

Answer 1

在Controller中创建表单时，您应该在其中传递一个新的实体：

$etatSuiviDossier = new EtatSuiviDossier();
$form = $this->createForm(EtatSuiviDossierType::class, $etatSuiviDossier);
$form->handleRequest($request);

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

    $etatSuiviDossier // here is your entity with formdata

    // save your entity
    $em = $this->getDoctrine()->getManager();
    $em->persist($etatSuiviDossier);
    $em->flush();

}

实体自动填充。
