Django compressor and manage.py compress problems

Question

My problem: When debug=true in settings.py django compress works just fine, takes all the js concatenates everything and minifies, when debug-false is basically useless: if i set COMPRESS_ENABLED = True (default when debug=false) i get a 500 error, but don't really know what's going on:

It:mysite italo$ ./manage.py runserver Performing system checks...

looks like i get several javascript files loaded (apparently not concatenating at all) but the css files are minified... my solution used to be to set COMPRESS_ENABLED = False on production and then write a script to do:

1) collectstatic

2) compress --force (because ompressor is disabled, i tried to enable it temporary before running runserver and using just compress but i get the same results)

3) runserver

What i get is separate files and they're not minified, I don't get any error, but having different non minified js files is pretty much useless IMHO.

i tried

using ALLOWED_HOSTS = ['*']
updating to the latest version in compressor
disabling whitenoise
ALLOWED_HOSTS = ['*']
disabling css processor (even though sass compilation is ok i just don't get concatenation when debug=false)

this is suggested in many posts but doesn't work. My first question: how do i fix this?

I'm clueless and at this point my second question would be if there's a working alternative to django-compressor.

since the problem is related to the fact that django is not serving static files when debug=false, i decided to use this solution http://www.kennethreitz.org/essays/introducing-dj-static

it's a module called dj-static

the problem is now solved.
