Symfony 3系列数量一到一对，FK是无效的

Question

我有一对一的colletion，其中2个集合在起作用，但是cursuri（可变的名称）没有获得纪律的ID，null.laboratoare和引用正在工作为什么？我尝试了所有我看到的唯一区别是名字。纪律实体

        ->add("locatieLaborator")
        ->add("descriere")
        ->add("personal")
        ->add('laboratoare',CollectionType::class,[
            'entry_type'=>LaboratorForm::class,
            'allow_add' => true,
            'by_reference' => false,

遏制，引用和Laboratoare是相同的形式，只有名称被更改

   <?php
   namespace AppBundleForm;
  use AppBundleEntityCurs;
  use SymfonyComponentFormAbstractType;
 use SymfonyComponentFormFormBuilderInterface;
 use SymfonyComponentOptionsResolverOptionsResolver;
 use VichUploaderBundleFormTypeVichFileType;
  class CursForm extends AbstractType
 {
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add("nume")
        ->add("ordine")
        ->add('file', VichFileType::class, [
            'required' => false,
            'allow_delete' => false, // not mandatory, default is true
            'download_link' => false, // not mandatory, default is true
        ]);
}
public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults([
        'data_class' => Curs::class
    ]);
}
}

控制器

      /**
    * @param $name
     * @return SymfonyComponentHttpFoundationResponse
    * @Route("/adauga/disciplina",name="adauga_disciplina")
    */
    public function newAction(Request $request)
   {
    $form = $this->createForm(DisciplinaForm::class);
    // only handles data on POST
    $form->handleRequest($request);
    if ($form->isSubmitted() && $form->isValid()) {
        $disciplina = $form->getData();
        $em = $this->getDoctrine()->getManager();
        $em->persist($disciplina);
        $em->flush();
        $this->addFlash(
            'success',
            sprintf('Disciplina adaugata.')
        );
        return $this->redirectToRoute('adauga_disciplina');
    }
    return $this->render('disciplina/adauga_disciplina.html.twig',[
        'form'=>$form->createView()
    ]);
  }

这几乎是不可能的，只有名称是不同的，并且不起作用。laboratoare和引用在起作用，但是cursuri却没有。任何帮助？

Answer 1

我必须运行那些控制台命令

php vendor/bin/doctrine.php orm:clear-cache:result
php vendor/bin/doctrine.php orm:clear-cache:query
php vendor/bin/doctrine.php orm:clear-cache:metadata

加上愚蠢的表单调用方法addcourse而不是addCourses，它给了我id null，用于reall ???????？

Answer 2

我对您的建议就是在实体类中建立您的关系，然后让机器人通过发行：

来完成所有工作的工作。

php bin/console doctrine:generate:entities AppBundle:Curs

这将确保您拥有所有必要的方法。因为，例如，您拥有未使用的setCursuri()方法。相反，您需要addCurs(AppBundleEntityCurs $curs)，removeCurs(AppBundleEntityCurs $curs)和getCursuri()。
