Symfony 4 - Object of class could not be converted to String - php

Question

After looking over the internet and here I didn' find something useful for me.
I'm currently creating a CRUD. Every 'Entreprise' having one or multiple 'Site' and I'm currently doing the CRUD for Site. I've made it by doing the make:form command.
Whhen I'm going to create a site the following error appear :
Catchable Fatal Error: Object of class App\Entity\Entreprise could not
be converted to string
I've tried to add the function __toString() as i saw. But maybe i didn't add it crrectly it changes nothing so I removed it.
My controller to create a site looks like this :
/**
* #Route("admin/sites/new", name="admin.sites.new")
* #param Request $request
* #return RedirectResponse|Response
*/
public function new (Request $request)
{
$site = new Site();
$form = $this->createForm(SiteType::class, $site);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()){
$this->em->persist($site);
$this->em->flush();
$this->addFlash('success', 'Site crée avec succès');
return $this->redirectToRoute('admin.sites.index');
}
return $this->render('admin/sites/create.html.twig', [
'site' => $site,
'form' => $form->createView()
]);
}
}
My SiteType generate by the make:form commande :
/**
* #Route("admin/sites/new", name="admin.sites.new")
* #param Request $request
* #return RedirectResponse|Response
*/
public function new (Request $request)
{
$site = new Site();
$form = $this->createForm(SiteType::class, $site);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()){
$this->em->persist($site);
$this->em->flush();
$this->addFlash('success', 'Site crée avec succès');
return $this->redirectToRoute('admin.sites.index');
}
return $this->render('admin/sites/create.html.twig', [
'site' => $site,
'form' => $form->createView()
]);
}
}
So here are my ENTITY
Entreprise
namespace App\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;
/**

// set the owning side to null (unless already changed)
if ($entrepriseId->getEntrepriseId() === $this) {
$entrepriseId->setEntrepriseId(null);
}
}
return $this;
}
}
And here is
Site

use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;

public function __construct()
{
$this->site_id = new ArrayCollection();
}
public function getId(): ?int
{

}
public function getSiteNom(): ?string
{
return $this->site_nom;
}
public function setSiteNom(string $site_nom): self
{
$this->site_nom = $site_nom;
return $this;
}
public function getSiteRaisonSociale(): ?string
{
return $this->site_raison_sociale;
}
public function setSiteRaisonSociale(string $site_raison_sociale): self
{
$this->site_raison_sociale = $site_raison_sociale;
return $this;
}
public function getSiteAPE(): ?string
{
return $this->site_APE;
}
public function setSiteAPE(string $site_APE): self
{
$this->site_APE = $site_APE;
return $this;
}
/**

*/
public function getSiteId(): Collection
{
return $this->site_id;
}
public function addSiteId(Client $siteId): self
{
if (!$this->site_id->contains($siteId)) {
$this->site_id[] = $siteId;
$siteId->addSiteId($this);
}
return $this;
}
public function removeSiteId(Client $siteId): self
{

}
return $this;
}
public function getAdresseId(): ?Adresse

}
public function setAdresseId(Adresse $adresse_id): self
{
$this->adresse_id = $adresse_id;
return $this;
}
public function getEntrepriseId(): ?Entreprise
{
return $this->entreprise_id;
}
public function setEntrepriseId(?Entreprise $entreprise_id): self
{
$this->entreprise_id = $entreprise_id;
return $this;
}
public function __toString()
{
return $this->getSiteNom();
}
}
I didn't know what's wrong. Maybe the __toString I didn't write correclty !
I've wrote :
public function __toString()
{
return $this->getSiteNom();
}
}

Catchable Fatal Error: Object of class App\Entity\Entreprise
You need to implement the __toString() method in the Entreprise entity
namespace App\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity(repositoryClass="App\Repository\EntrepriseRepository")
*/
class Entreprise
{
//...
public function __toString()
{
return $this->entreprise_nom;
}
// ...
}
