I'm trying to inject EntityManagerInterface in my custom validator, but I have this error:
Attempted to load class "validator_check_client_id" from the global namespace.
Did you forget a "use" statement?
My code is:
CheckClientId.php
namespace App\Validator;
use Symfony\Component\Validator\Constraint;
/**
* @Annotation
*/
class CheckClientId extends Constraint{
public $message = 'Test';
public function validatedBy(){
return 'validator_check_client_id';
}
}
CheckClientIdValidator.php
namespace App\Validator;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;
class CheckClientIdValidator extends ConstraintValidator{
private $entityManager;
public function __construct(EntityManagerInterface $entityManager) {
$this->entityManager = $entityManager;
}
public function validate($value, Constraint $constraint){
//Todo
return;
}
}
services.yaml
validator.check_client_id:
class: App\Validator\CheckClientIdValidator
autowire: false
arguments:
$entityManager: '@doctrine.orm.entity_manager'
tags:
- {
name: validator.constraint_validator,
alias: validator_check_client_id,
}
Should I do an extra step to register my service? I think that symfony cannot find it because it is not properly registered.
I also tried to do what this answer says symfony validator as service not working, but I get a similar error:
Attempted to load class "app.validator.blog.slug_unique" from the global namespace.
Did you forget a "use" statement?
Do you have any idea what is happening?
Thank you for your help!
Thanks to autowire and autoconfig, all you really have to do is to get your class names right. No changes to services.yaml. Here is a working example using a fresh 5.2 project.
# src/Validator/CheckClientId.php
namespace App\Validator;
use Symfony\Component\Validator\Constraint;
/** @Annotation */
class CheckClientId extends Constraint
{
public $message = 'CheckClientId';
}
# =============================
# src/Validator/CheckClientIdValidator
namespace App\Validator;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;
use Symfony\Component\Validator\Exception\UnexpectedValueException;
class CheckClientIdValidator extends ConstraintValidator
{
public function __construct(private EntityManagerInterface $entityManager)
{
}
public function validate($value, Constraint $constraint)
{
dump('validate ' . $value);
throw new UnexpectedValueException($value, 'string');
}
}
# ===============================
# Test Entity
# src/Entity/Client.php
namespace App\Entity;
use App\Validator as AcmeAssert;
class Client
{
/** @AcmeAssert\CheckClientId */
public $id = 42;
}
# ====================================
# Test Command
# src/Command/ValidateCommand
namespace App\Command;
use App\Entity\Client;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Symfony\Component\Validator\Validator\ValidatorInterface;
class ValidateCommand extends Command
{
protected static $defaultName = 'test:validator';
public function __construct(private ValidatorInterface $validator)
{
parent::__construct();
}
protected function execute(InputInterface $input, OutputInterface $output): int
{
$client = new Client();
$errors = $this->validator->validate($client);
echo $errors;
return Command::SUCCESS;
}
}
Get the test command working and move on from there.
