Adding JS and CSS cleanly from included Twig templates
I know I'm a little late to the party, but with Twig 1.2, you can utilize the use tag and the block function:
GenericBundle:Generic:page.html.twig
{% block javascripts %} <script src="..."></script>{% endblock %}{% block included_content %} Bar{% endblock %}layout.html.twig
{% use 'GenericBundle:Generic:page.html.twig' with javascripts as page_javascripts %}{% block javascript %} {% javascripts '@GenericBundle/Resources/public/js/app/jquery/jquery.min.js' '@GenericBundle/Resources/public/js/lib/bootstrap/bootstrap.min.js' %} <script src="{{ asset_url }}"></script> {% endjavascripts %} {{ block('page_javascript') }} // Don't forget the 'braces'{% endblock %}...{{ block('included_content') }} // Don't forget the 'braces'
