An exception occurred while executing a query: SQLSTATE[23000] - php

Question

I've got a problem.
When I want to create an article, it shows me this error.
And when I want to edit one, it doesn't change anything.
It was working before, but then I've added category and comment section.
Can you help me ?
here is my Controller:
<?php
namespace App\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use App\Entity\Article;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Doctrine\ORM\EntityManagerInterface;
use Doctrine\Persistence\ManagerRegistry;
use Doctrine\Persistence\ObjectManager;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\TextareaType;
use Symfony\Component\Form\Extension\HttpFoundation\HttpFoundationExtension;
use Symfony\Component\Form\Forms;
use Symfony\Component\HttpFoundation\Request;
use App\Form\ArticleType;
class BlogController extends AbstractController
{
#[Route('/blog', name: 'blog')]
public function index(ManagerRegistry $doctrine): Response
{
$articles = $doctrine->getRepository(Article::class)->findAll();
return $this->render('blog/index.html.twig', [
'controller_name' => 'BlogController',
'articles' => $articles,
]);
}
#[Route("/", name: 'home')]
public function home() {
return $this->render('blog/home.html.twig', [
'title' => "Bienvenue",
'age' => 31,
]);
}
#[Route("/blog/new", name: 'blog_create')]
#[Route("/blog/{id}/edit", name: 'blog_edit')]
public function form(Article $article = null, Request $request, EntityManagerInterface $manager) {
// si on a pas d'article, donc on est en new
if(!$article){
$article = new Article();
}
$form = $this->createForm(ArticleType::class);
$form->handleRequest($request);
//si on a appuyer sur le bouton et que infos valides, on peut envoyer
if($form->isSubmitted() && $form->isValid()){
$manager->persist($article);
$manager->flush();
// on redirige vers l'article crée ou modifié
return $this->redirectToRoute('blog_show', ['id' => $article->getId()]);
}
return $this->render('blog/create.html.twig', [
'formArticle' => $form->createView(),
// edit Mode a true si il y a un article
'editMode' => $article->getId() !== null,
]);
}
#[Route("/blog/{id}", name: 'blog_show')]
public function show(ManagerRegistry $doctrine , $id){
$repo = $doctrine->getRepository(Article::class);
$article = $repo->find($id);
return $this->render('blog/show.html.twig', [
'article' => $article,
]);
}
}
And now, my form:
<?php
namespace App\Form;
use App\Entity\Article;
use App\Entity\Category;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
class ArticleType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options): void
{
$builder
->add('title')
->add('category', EntityType::class, [
'class' => Category::class,
'choice_label' => 'title',
])
->add('content')
->add('image')
;
}
public function configureOptions(OptionsResolver $resolver): void
{
$resolver->setDefaults([
'data_class' => Article::class,
]);
}
}
To end with my Entities:
Article

}

Thanks in advance guys :))
I won't add the twig file cause it's normal file

Answer 1

I succeeded.
In the controllers, I just added:
$this->createForm(ArticleType::class, $article);
