L'inclusion du render dans le layout

{% block langue_switcher %}
    <div id="langue_switcher" class="span-9 pull-1 last">
        {% render "IMAGBaseCallsBundle:Base:languages" with {'request': app.request} %}
    </div>
{% endblock langue_switcher %}

A savoir

#Parts of Symfony web site

#You can check if you are using the internal routes easily by running the following command:

$ php ./app/console cache:clear
$ php ./app/console router:debug _internal

#If you have an error that says The route "_internal" does not exist., you are not vulnerable.
