I tried to run the fixture below on Symfony 5 using the command php bin/console d:f:l
.
I get this error: SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'contact_email' cannot be null
The same code logic is working fine for Post entities when creating them manually through the CRUD. Are fixtures not compatible with subscribers (events) or did i make a mistake?
Thank you.
Edit: I'm also using EasyAdmin Bundle 3.
<?php
namespace App\DataFixtures;
use App\Entity\User;
use App\Entity\Author;
use Doctrine\Persistence\ObjectManager;
use Doctrine\Bundle\FixturesBundle\Fixture;
use Symfony\Component\PasswordHasher\Hasher\UserPasswordHasherInterface;
class AppFixtures extends Fixture
{
/** @var User[] */
private $users = [];
/** @var Author[] */
private $authors = [];
/** @var UserPasswordHasherInterface */
private $hasher;
public function __construct(UserPasswordHasherInterface $hasher)
{
$this->hasher = $hasher;
}
public function load(ObjectManager $manager): void
{
$this->createUsers();
foreach($this->users as $user) $manager->persist($user);
$this->createAuthors();
foreach($this->authors as $author) $manager->persist($author);
$manager->flush();
}
public function createUsers(): void
{
$admin = (new User)
->setUsername('admin')
->setEmail('admin@admin.com')
->setRoles(['ROLE_ADMIN'])
->setFirstname('Edouard')
->setLastname('Proust');
$admin->setPassword($this->hasher->hashPassword($admin, 'admin'));
$this->users[] = $admin;
}
public function createAuthors(): void
{
foreach($this->users as $user) {
if(in_array('ROLE_ADMIN', $user->getRoles())) {
$author = (new Author)
->setUser($user)
->setAvatar('#')
->setBio('Bio')
// The line i want to get rid of:
// ->setContactEmail($user->getEmail())
;
$this->authors[] = $author;
}
}
}
}
<?php
namespace App\EventListener;
use App\Entity\Author;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use EasyCorp\Bundle\EasyAdminBundle\Event\BeforeEntityPersistedEvent;
class AuthorSubscriber implements EventSubscriberInterface
{
public static function getSubscribedEvents()
{
return [
BeforeEntityPersistedEvent::class => 'setContactEmail',
];
}
public function setContactEmail(BeforeEntityPersistedEvent $event)
{
/** @var Author */
$entity = $event->getEntityInstance();
if($entity instanceof Author) {
if(!$entity->getContactEmail()) {
$user = $entity->getUser();
$contactEmail = $user ? $user->getEmail() : '#';
$entity->setContactEmail($contactEmail);
}
}
}
}
EasyCorp\Bundle\EasyAdminBundle\Event\BeforeEntityPersistedEvent:class
is not proper Symfony event name. You probably should use Doctrine\ORM\Events::prePersist
.
Also please check your DoctrineBundle version. If you're using the default services.yaml configuration and DoctrineBundle lower than 2.1, you have to configure services.yaml
with:
App\EventListener\AuthorSubscriber:
tags:
- name: 'doctrine.event_subscriber'
