Ограничитель валидатор не

Я следую учебнику Symfony по проверке формы.

Здесь $ title должен оцениваться как уникальное право, и это работает, но то же сообщение об ошибке отображается в поле $ content.

Кроме того, я также пытаюсь получить контент для проверки с помощью ограничения «Antiflood» и его «Validator». (когда я комментирую проверку заголовка и пытаюсь, по крайней мере, заставить работать Antiflood …), я понимаю, что это работает (форма не проверяется), но я не получил сообщение об ошибке …

Ошибка проверки заголовка (двойное сообщение)

Ошибка с constraintValidator (работает, но без сообщения)

Мое ограничение

<?php
// src/OC/PlatformBundle/Validator/Antiflood.php

namespace OC\PlatformBundle\Validator;

use Symfony\Component\Validator\Constraint;

/**
* @Annotation
*/
class Antiflood extends Constraint
{
public $message = "Vous avez déjà posté un message il y a moins de 15 secondes, merci d'attendre un peu.";
}

Мой валидатор

<?php
// src/OC/PlatformBundle/Validator/AntifloodValidator.php

namespace OC\PlatformBundle\Validator;

use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;

class AntifloodValidator extends ConstraintValidator
{
public function validate($value, Constraint $constraint)
{
// Pour l'instant, on considère comme flood tout message de moins de 3 caractères
if (strlen($value) < 3) {
// C'est cette ligne qui déclenche l'erreur pour le formulaire, avec en argument le message de la contrainte
$this->context->addViolation($constraint->message);
}
}
}
