如何在一对多关系Symfony中设置相关实体id？

Question

我试图坚持两个实体，它们有一对一和多对一的关系。

我正在尝试将表单集合嵌入到表单中。

我有一个多对一相关的实体，每次我创建一个新的课程简历，它与Candidat列相关candidat_id_id为空。

除了数据可数据中的Candidat id之外，只有实体Curendar umVitae被成功创建和持久化。

• 简历表

id|titre|candidat_id_id|id_education

candidat_id_id是：null

id\U教育具有以下价值：条令\公共\收藏\ArrayCollection@000000003d585f990000000052235238

• 教育表为空

id |描述| id\U履历表\U简历id

我的问题是id\U履历和id\U教育。

简历实体：

/**
 * CurriculumVitae
 *
 * @ORM\Table(name="curriculum_vitae")
 * @ORM\Entity(repositoryClass="GE\CandidatBundle\Repository\CurriculumVitaeRepository")
 */
class CurriculumVitae
{
    /**
     * @var Candidat
     *
     * @ORM\ManyToOne(targetEntity="GE\CandidatBundle\Entity\Candidat")
     */
    protected $candidatId;

    /**
     * @var Education
     * @ORM\OneToMany(targetEntity="GE\CandidatBundle\Entity\Education", mappedBy="idCurriculumVitae", cascade={"persist", "remove"})
     * @ORM\Column(name="id_education")
     */
    protected $educations;

/**
 * Add education
 *
 * @param \GE\CandidatBundle\Entity\Education $education
 *
 * @return CurriculumVitae
 */
public function addEducation(\GE\CandidatBundle\Entity\Education $education)
{
    $this->educations[] = $education;
    $education->setCurriculumVitae($this);
    return $this;
}

/**
 * Remove education
 *
 * @param \GE\CandidatBundle\Entity\Education $education
 */
public function removeEducation(\GE\CandidatBundle\Entity\Education $education)
{
    $this->educations->removeElement($education);
}
}

教育实体：

/**
 * Education
 *
 * @ORM\Table(name="education")
 * @ORM\Entity(repositoryClass="GE\CandidatBundle\Repository\EducationRepository")
 */
class Education
{
    ...
    /**
     * @var CurriculumVitae
     * @ORM\ManyToOne(targetEntity="GE\CandidatBundle\Entity\CurriculumVitae")
     */
    private $idCurriculumVitae;
}

简历控制员：

class CurriculumVitaeController extends Controller
{
    /**
     * Creates a new curriculumVitae entity.
     *
     * @Route("/candidat/cv/ajouter", name="cv_new")
     * @Method({"GET", "POST"})
     */
    public function newAction(Request $request)
    {
        $curriculumVitae = new Curriculumvitae();
        $form = $this->createForm('GE\CandidatBundle\Form\CurriculumVitaeType', $curriculumVitae);
        $form->handleRequest($request);

        if ($form->isSubmitted() && $form->isValid()) {
            $em = $this->getDoctrine()->getManager();
            $em->persist($curriculumVitae);
            $em->flush();
            $request->getSession()
                ->getFlashBag()
                ->add('infoCv', 'Votre cv a été bien enregistrée.');

            return $this->redirectToRoute('cv_show', array('id' => $curriculumVitae->getId()));
        }

        return $this->render('curriculumvitae/new.html.twig', array(
            'curriculumVitae' => $curriculumVitae,
            'form' => $form->createView(),
        ));
    }
}

课程简历类型：

public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('candidat', EntityType::class, array(
            'class' => 'GECandidatBundle:Candidat',
            'choice_label' => 'id',
            'multiple'      => false,
            ))
            ->add('educations',
                CollectionType::class, [
                    'entry_type' => EducationType::class,
                    'allow_add' => true,
                    'allow_delete' => true,
                    'prototype' => true,
                    'by_reference' => false,
                    'label' => 'Educations:'
                ]
            )
        ;
    }

Answer 1

对不起，我发现了我的问题。

必须在控制器中定义id。

$curriculumVitae->setCandidat($candidat);

Answer 2

尝试此代码并更新您数据库的模式/** * @var Curendar umVitae*@ORM\ManyToOne（Target etEntity="GE\CandidatBundle\Entity\Curendar umVitae"）*@ORM\JoinCol列（name="CandidatId"，引用的列名称="id"， onDelete="SET NULL"）*/Private$idCurendar umVitae；
