php - Symfony validation only on new form

My validation works for creating a new entity, and not allowing a duplicate description.

How do I make this validation work for updating an entity, as it is, when updating the entity the validator is invoked and displays an error.

I'm still learning Symfony so please let me know any further details I need to provide.

descUnique.php

use Symfony\Component\Validator\Constraint;

/**
 * @Annotation
 */
class descUnique extends Constraint
{
    public $message = 'The description "{{ value }}" is allready in use.';
}
Copy code

descUniqueValidator.php

class descUniqueValidator extends ConstraintValidator {

    /**
     * @var Security
     */
    private $security;

    /**
     * @var Em
     */
    private $em;

    public function __construct(EntityManagerInterface $em, Security $security) {
        $this->em = $em;
        $this->security = $security;
    }

    public function validate($value, Constraint $constraint) {
        /* @var $constraint \App\Validator\descUnique */

        if (null === $value || '' === $value) {
            return;
        }

        $repo = $this->em->getRepository(Carrier::class)
                ->findUniqueName($this->security->getUser(), $value);

        
        if ($repo) {
            $this->context->buildViolation($constraint->message)
                    ->setParameter('{{ value }}', $value)
                    ->addViolation();
        }
    }

}
Copy code

edit

My validator declaration in the entity object.

    /**
     * @ORM\Column(type="string", length=100)
     * @Validator\CarrierDescUnique
     */
    private $description;
