In symfony2 with sonata: How to pass a variable to the template defined for a given field of the listmapper in the method configureListFields?

Question

Using Symfony2 with Sonata, in a list, fields templates can be overwritten and assigning variables to templates, i.e setTemplateVar(), can sometimes be useful! (not talking about form where 'attr' serves this purpose but list...)

I would like to know what would be the best approach to pass a variable to the template defined for a given field of the listmapper in the method configureListFields ?

    <?php

    namespace Acme\AcmeBundle\Admin;

    use Sonata\AdminBundle\Admin\Admin;
    use Sonata\AdminBundle\Datagrid\ListMapper;
    use Sonata\AdminBundle\Datagrid\DatagridMapper;
    use Sonata\AdminBundle\Validator\ErrorElement;
    use Sonata\AdminBundle\Form\FormMapper;

    class AcmeAdmin extends Admin
    {

        protected function configureListFields(ListMapper $listMapper)
        {
            $listMapper
                ->addIdentifier('acme_field')
                ->add('date', 'date', array(
                    'template'   => "AcmeBundle:CRUD:list_date.html.twig",
            //        'dateFormat' => "Y-m-d",// ---> how to pass this var to twig ?
                ))
                ->add('_action', 'actions', array(
                    'actions' => array(
                        'edit'   => array(),
                        'delete' => array(),
                    ),
                ))
            ;
        }

A solution to the specific problem of translating and formatting the date is already implemented with the twig template as follows:

    {% block field%}
        {% if value is empty %}
             
        {% else %}

            {# retrieving the dateFormat variable from the listmapper #}
            {% if dateFormat is defined %}
                {{ value|date(dateFormat)|title }}
            {% else %}
                {{ value|date('m / Y') }}
            {% endif %}

            {# passing the locale in some way here would be great, it is not available in twig.. #}
            {# scratch that, it is not necessary with intl.extension... #}
            {% if locale is defined %}
                {% set dflt_locale = locale %}
            {% else %}
                {% set dflt_locale = 'fr_FR.UTF-8' %}
            {% endif %}

            {{ value|localizeddate('medium', 'none', dflt_locale)|title }}

        {% endif %}
    {% endblock %}

However, my goal is to be able to retrieve a variable there from the listmapper.
In the example proposed, the dateFormat would be a good one to pass along...

The issue about the locale is fine actually, as I realized it does not need to be passed to localizeddate... it is already available through the intl extension.

The following post answer lead me to that conclusion as I could not define locale, but by not adding the parameter it was resolved! Localize dates in twigs using Symfony 2 hence:

    {{ value|localizeddate('medium', 'none')|title }}

Cheers in advance for any response related to the dateFormat parameter!

Try in the Twig

field_description.options.YOURFIELDNAME

defined here

->add('date', 'date', array(
                    'template'   => "AcmeBundle:CRUD:list_date.html.twig",
                    'YOURFIELDNAME' => 'Blablo'
                ))

Cheers
