Symfony2 Assetic + Twig Template JavaScript Inheritance

Question

My problem:

I have 3 templates:

• main.html.twig (main layout file)
• layout.html.twig (a bundle specific layout override which contains some bundle specific JS tags)
• create.html.twig (a page specific template file which also contains some page specific JS tags)

I am defining a block called 'javascript' in my base layout (main.html.twig), then overriding it (but calling {{ parent() }} in layout.html.twig. This works fine, and the JS tags from the main template file are still included above those in the layout.html.twig template.

I then do the same in the create.html.twig file, overriding the block as follows:

{% block javascripts %}
    {{ parent() }}
    {% javascripts '@BundleName/Resources/public/js/application.album.uploader.js'
                   '@BundleName/Resources/public/js/jquery.uploadify.js'
                   '@BundleName/Resources/public/js/swfuploadify.js' filter='?yui_js' %}
         <script src='{{ asset_url }}' type='text/javascript'></script>
    {% endjavascripts %}
{% endblock %}

At this point, instead of just overriding the javascript block in the parent (layout.html.twig) and including all the scripts defined in the templates above it, it does the following:

• Dumps the <script> tags in the middle of the output (which causes an error, because in my main.html.twig file I am only including the jQuery library at the end of the HTML markup
• Then it also dumps the scripts out along with the rest of the others (as I would expect it to)

I am not sure what is causing the scripts to be dumped in the middle of the create.html.twig template, and I'm also confused as to why they're being dumped to the screen twice (once in the middle of the create and then once at the bottom along with all the rest of my scripts from main.html.twig and layout.html.twig.

Has anyone got any ideas? Let me know if anything is unclear or if I can provide some more information.

EDIT 2:

I've been having another look at the issue this morning and it looks as though its doing the same thing for stylesheets. I tried to define a new block called pagescripts in my layout.html.twig and then use the block in my create.html.twig but this had the same outcome, it just seems to dump the scripts and stylesheets wherever I use the

{% block pagescripts %} 
   (scripts here) 
{% endblock}

Answer 1

I found the issue. In create.html.twig I was defining my {% block javascripts %} content inside inside my {% block content %}, so I assume Twig was rendering the output of the javascripts block inside the content block.

Moving the {% block javascripts %} content outside of the {% block content %} block fixed the issue.
