symfony2 persist manyToOne - symfony

Question

i Have a single page application and i use symfony as a Rest API.
In my object "ResidenceIntervenant, i have a ManyToOne relation :
manyToOne:
intervenant:
targetEntity: Intervenant
cascade: { }
fetch: LAZY
mappedBy: null
inversedBy: null
joinColumns:
intervenant_id:
referencedColumnName: id
orphanRemoval: false
When i do this :
$myData = json_decode($request->getContent(), true);
$intervenant = $this->em->getRepository('AppBundle:Intervenant')->find($intervenantId);
$relation = new ResidenceIntervenant();
$myData['intervenant'] = $intervenant->getId();
$form_relation = $this->formFactory->create(ResidenceIntervenantType::class, $relation, ['method' => "POST"]);
$form_relation->submit($myData, TRUE);
if ( ! $form_relation->isValid()) {
$this->em->persist($relation);
$this->em->flush();
}
it works and i have the id in my table
When i do :
$myData = json_decode($request->getContent(), true);
$intervenant = $this->em->getRepository('AppBundle:Intervenant')->find($intervenantId);
$relation = new ResidenceIntervenant();
$relation->setIntervenant($intervenant);
$form_relation = $this->formFactory->create(ResidenceIntervenantType::class, $relation, ['method' => "POST"]);
$form_relation->submit($myData, TRUE);
if ( ! $form_relation->isValid()) {
$this->em->persist($relation);
$this->em->flush();
}
it doesn't persists the id
Is this normal ?
my FormType biuldForm method :
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('contratNum')
->add('appareilNum')
->add('intervenantOrigine')
->add('intervenant')
->add('residence');
}
Thanks for your help
EDIT : add informations to show my entities
I tried to add these linee but it neither works:
$intervenant->addResidenceIntervenant($relation);
$this->em->persist($intervenant);
$this->em->flush();

EDIT : Problem solved
i updated addResidenceIntervenant like this :
public function addResidenceIntervenant(\AppBundle\Entity\ResidenceIntervenant $residenceIntervenant)
{
$this->residenceIntervenant[] = $residenceIntervenant;
$residenceIntervenant->setIntervenant($this);
return $this;
}
i added these lines after persisting my relation :
$intervenant->addResidenceIntervenant($relation);
$this->em->persist($intervenant);

Answer 1

Your second example has this line:
$relation->setIntervenant($intervenant);
Does the method setIntervenant() set the relation?
I think you should do something like this:
public function setIntervenant(Intervenant $intervenant)
{
$this->intervenant = $intervenant;
$intervenant->setResidence($this);
}
Anyway, the relations in Doctrine can be unidirectional or bidirectional.
Your Many-To-One relation seems to be unidirectional. You should set a One-To-Many relation on your Intervenant entity.
Read more about this in the Doctrine documentation:
Many-to-One, Unidirectional (This is what you did)
One-to-Many, bidirectional (This is what you should do)
One-To-Many, Unidirectional with Join Table (Just for completeness)
So, you should trait your Intervenant as the Doctrine treats the Feature while your ResidenceIntervenant has to be treated as the Product in the Doctrine documentation.
