我有一个到多个集合，其中2个集合正在工作但是cursuri（变量名称）没有得到门徒的id是null.Laboratoare和referate工作为什么？我尝试了一切唯一的区别我看到的是这个名字。 Disciplina实体

 use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\CollectionType;
use Symfony\Component\Form\FormBuilderInterface;

 use Vich\UploaderBundle\Form\Type\VichFileType;

 class DisciplinaForm extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('imageFile', VichFileType::class, [
            'required' => false,

CursForm，referate和laboratoare是相同的形式，只有名称被更改

   <?php

   namespace AppBundle\Form;

  use AppBundle\Entity\Curs;
  use Symfony\Component\Form\AbstractType;
 use Symfony\Component\Form\FormBuilderInterface;
 use Symfony\Component\OptionsResolver\OptionsResolver;
 use Vich\UploaderBundle\Form\Type\VichFileType;

  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 \Symfony\Component\HttpFoundation\Response
    * @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字不同而且不起作用。实验和遗嘱正在运作但是cursuri不是。任何帮助？

2 个答案:

答案 0 :(得分：0)

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

另外，愚蠢的形式是调用方法addCourse而不是addCourses，它给了我id null，对于reall ???????要验证这一点，你可以删除setCourses方法，它会告诉你想要的方法。

答案 1 :(得分：0)

我对你的建议是在实体课程中建立你的关系，然后让机器人完成剩下的工作，发出：

Foo

这将确保您拥有所有必需的方法。例如，因为您拥有未使用的php bin/console doctrine:generate:entities AppBundle:Curs 方法。相反，您需要setCursuri()，addCurs(\AppBundle\Entity\Curs $curs)和removeCurs(\AppBundle\Entity\Curs $curs)。
