There are two issues:

  1. AFAIK using query string parameter may cause some browsers not to cache scripts

  2. there already is nice solution for this kind of stuff: django-compress

I had my own solution, similiar to yours, but when django-compress appeared I've switched to it and so far I'm very happy with this.

I used django_templatecomponents which provides most of the minification and grouping features django-compress does.

In regards to the query string causing some browsers not to cache scripts, can you elaborate?

For my applications I don't really need to support older browsers.
