Trying to insert data ManyToOne FOSRestBundle - rest

Question

I'm trying to creating an API REST with the bundle FOSRestBundle (SF5).
I've an entity "Categorie" which can have an parent "Categorie".
Here is the entity :
<?php
namespace App\Entity\Main;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
use JMS\Serializer\Annotation\Expose;
use JMS\Serializer\Annotation\ExclusionPolicy;
use Symfony\Component\Validator\Constraints as Assert;
/**
* #ORM\Entity(repositoryClass="App\Repository\CategorieRepository")
* #ORM\Table(name="categorie")
* #ExclusionPolicy("all")
*/
class Categorie
{
/**
* #ORM\Id()
* #ORM\GeneratedValue()
* #Expose
* #ORM\Column(type="integer")
*/
private $id;
/**
* #var string
* #Assert\NotBlank()
* #Expose
* #ORM\Column(type="string", length=255)
*/
private $libelle;
/**
* #var string
* #Assert\NotBlank()
* #Expose
* #ORM\Column(type="string", length=255)
*/
private $icone;
/**
* #var Categorie
* #ORM\ManyToOne(targetEntity="App\Entity\Main\Categorie", inversedBy="categories", cascade={"all"}, fetch="EAGER")
* #ORM\JoinColumn(name="categorie_parent_id", referencedColumnName="id", nullable=true)
*/
private $categorieParent;
/**
* #var ArrayCollection
* #ORM\OneToMany(targetEntity="App\Entity\Main\Categorie", mappedBy="categorieParent")
*/
private $categories;
/**
* #var ArrayCollection
* #ORM\OneToMany(targetEntity="App\Entity\Main\Produit", mappedBy="categorie")
*/
private $produits;
public function __construct()
{
$this->produits = new ArrayCollection();
}
public function getId(): ?int
{
return $this->id;
}
public function getLibelle(): ?string
{
return $this->libelle;
}
public function setLibelle(string $libelle): self
{
$this->libelle = $libelle;
return $this;
}
public function getIcone(): ?string
{
return $this->icone;
}
public function setIcone(string $icone): self
{
$this->icone = $icone;
return $this;
}
public function setCategorieParent(Categorie $categorieParent): self
{
$this->categorieParent = $categorieParent;
return $this;
}
public function getCategorieParent(Categorie $categorieParent)
{
return $this->categorieParent;
}
}
Here is my action in controller :
/**
* #Rest\View(statusCode=Response::HTTP_CREATED)
* #Rest\Post("/api/{_locale}/categorie/create", name="api_categorie_create")
* #ParamConverter("categorie", converter="fos_rest.request_body")
* #IsGranted("ROLE_SUPER_ADMIN")
* #return Categorie|View
*/
public function create(Categorie $categorie, ConstraintViolationList $violations)
{
if (count($violations)) {
return $this->view($violations, Response::HTTP_BAD_REQUEST);
}
$em = $this->getDoctrine()->getManager('main');
$em->persist($categorie);
$em->flush();
return $categorie;
}
When I use postman to insert data with this content :
{
"libelle":"Blonde",
"icone":"blonde.png",
"categorieParent.id": 1
}
"libelle" and "icone" are inserted but "categorieParent" wasn't set.
I've try :
{
"libelle":"Blonde",
"icone":"blonde.png",
"categorieParent": 1
}
{
"libelle":"Blonde",
"icone":"blonde.png",
"categorieParent": {
"id": 1
}
}
For each try, I set id with number and string.
And anything doesn't work.
Thx for help :) !

CategorieParent will only accept a Categorie entity; libelle and icone work because they are simple strings. You should use the passed integer to fetch the Entity, then save the values.
