Twig: Capa paraun formulario.

form_div_layout.html.twig

{% extends 'Form/form_div_layout.html.twig' %}

{#
   Extends from Symfony/Bridge/Twig/Resources/views/Form/form_div_layout.html.twig
   Overrides the form_errors block so it no longer uses transchoice (which
   was causing a problem).
#}

    <ul>
        {% for error in errors %}

                error.messageTemplate|trans(error.messageParameters, 'validators')
            }}</li>
        {% endfor %}
