Constraint validator not

Question

I'm following a symfony tutorial on form validation.

Here $title should be valued as unique entitity and it works, but the same error message shows up on $content field.

Aside, I'm tryng also to get the content to be validated form "Antiflood" Constraint and its "Validator". (when I comment the title validation and try at least to make the Antiflood works...) I realize it works (the form doesn't validate) but I got no error message...

Error with title validation (double message)

Error with constraintValidator (works but no message) My Constraint

<?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.";
    }

My validator

<?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);
    }
  }
}

Answer 1

Got it! I had {{ form_errors(form.title) }} instead of {{ form_errors(form.content) }} in the twig template :S
