Symfony entity constraints not respected on form used with ajax patch request - ajax

Question

On my symfony 6 project, I try to update a data with an Ajax request. First, I display an input tag with stimulus.js and then with an eventlistener I use the ajax request to handle and submit a form with the new value to check if it respect my entity asserts constraints. I try to update on property ('signature') from on Entity ('CompteClient').
My problem is that my constroller doesn't check asserts (not blank and length between 5 and 50) from my entity and always persist datas, even if it's not correct.
I already try to add constraint on my formBuilderType, but I always add the same result.
I used principally this page from documentation https://symfony.com/doc/current/form/direct_submit.html
Here's, part of my code :
-> in js, replace input by span tag while doing update :
afficherSpan(id, propriete){
let aModifier = document.getElementById(propriete+'-'+id)
let inputToDisplay = document.getElementById('input-'+propriete+'-'+id)
let contenu = inputToDisplay.value
this.enregistrer(id, propriete, contenu)
//Span
let spanToDisplay = document.createElement('span')
spanToDisplay.setAttribute('id', 'span-'+propriete+'-'+id)
spanToDisplay.innerText = contenu
//Replace
aModifier.replaceChild(spanToDisplay, inputToDisplay)
}
enregistrer(id, propriete, contenu){
fetch("compte/"+id+"/modifier/"+propriete+"/"+contenu,
{method: 'PATCH'}
)
.then(res => res.json())
.then(data => console.log(data))
.then(function() {
})
.catch(err => console.log(err))
}
-> my formBuilder :
class SignatureType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options): void
{
$builder
->add('signature', TextType::class, [
'required' => true,
]);
}
public function configureOptions(OptionsResolver $resolver): void
{
$resolver->setDefaults([
'data_class' => CompteClient::class,
'validation_groups' => ['app_compte_client']
]);
}
}
-> my property 'signature' from the CompteClient entity :
#[ORM\Column(type: 'string', length: 50)]
#[Groups(["CompteClient:item:post", "CompteClient:signature:patch"])]
#[Assert\NotBlank(message:'Veuillez renseigner une signature.', groups:["app_compte_client"])]
#[Assert\Length(min:5, max:50, minMessage:'Veuillez renseigner une signature valide (> ou = à 5 car.).', maxMessage:'Veuillez renseigner une signature valide (< ou = à 50 car.).', groups:["app_compte_client"])]
private $signature;
-> then my controller :
#[Route('/compte/{id}/modifier/{propriete}/{contenu}', name: 'comptes_modifier', methods:['PATCH'])]
public function modifier(CompteClientRepository $compteClientRepository, EntityManagerInterface $entityManager, Request $request, int $id, string $propriete, string $contenu): Response
{
$compteClient = $compteClientRepository->find($id);
try {
if($compteClient){
if($propriete == 'signature' && !empty($contenu)){
$form = $this->createForm(SignatureType::class, $compteClient);
if($request->isMethod("PATCH")){
$form->get('signature')->submit($contenu, false);
if($form->get('signature')->isSubmitted() && $form->get('signature')->isValid()){
$compteClient->setSignature($contenu);
$entityManager->persist($compteClient);
$entityManager->flush();
return new Response(
json_encode([
'message'=> $propriete.' du compte de '.$compteClient->getNomCompte().' mis à jour avec succès'
]),202
);
}else{
$errors = $form->getErrors(true, false);
return new Response(
json_encode([
'message'=> $errors
]),406
);
};
}
}
}
} catch (\Throwable $th) {
return new Response(
json_encode([
$th
]),500);
}
}
So, even if I try to update signature with a string with length = 2, It's update in the db.
Someone have an idea ?
