Django: auto minifying css/js files before release

Did you try django-compress ?

See http://djangopackages.com/grids/g/asset-managers/ for a fairly complete list of available asset managers for Django...

If you already are using django-compress, you should have a look at upgrading to django-pipeline, which is a well maintained fork, with a lot of new features. I encourage everyone to who is using django-compress to switch to django-pipeline instead: * django-pipeline documentation

Django-compress is no longer being maintained. Try https://github.com/cyberdelia/django-pipeline instead.
