How to set related entity id in one to many relationship Symfony? - symfony

Question

I am trying to persist two entities that have OneToMany and ManyToOne relationships.
I'm trying to embed a collection of forms inside a form.
I have a many to one related entities and everytime I create a new CurriculumVitae which is related to Candidat the column candidat_id_id is null.
Only the entity CurriculumVitae is successfully created and persisted except the Candidat id in the data datatable.
CurriculumVitae Table
id | titre | candidat_id_id | id_education
candidat_id_id is: null
id_education has this value: Doctrine\Common\Collections\ArrayCollection#000000003d585f990000000052235238
Education Table is empty
id | description | id_curriculum_vitae_id
My problem is with the id_curriculum_vitae_id and the id_education.
CurriculumVitae Entity:
/**
* 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);
}
}
Education Entity:
/**
* 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;
}
CurriculumVitaeController :
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(),
));
}
}
CurriculumVitaeType:
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

Try this code and update your database's schema
/**
* #var CurriculumVitae
* #ORM\ManyToOne(targetEntity="GE\CandidatBundle\Entity\CurriculumVitae")
*#ORM\JoinColumn(name="candidatId",referencedColumnName="id",onDelete="SET NULL")
*/
private $idCurriculumVitae;

Answer 2

Sorry, i found my problem.
the id must be defined in the Controller.
$curriculumVitae->setCandidat($candidat);
