Turn off caching of static files in Django development server

@Erik Forsberg’s answer worked for me. Here’s what I had to do:

• Comment out the staticfiles app from INSTALLED_APPS in settings.py:

  INSTALLED_APPS = (
      'django.contrib.auth',
      'django.contrib.contenttypes',
      'django.contrib.sessions',
      'django.contrib.sites',
      'django.contrib.messages',
      #'django.contrib.staticfiles',
  )
  

• Leave my STATIC_URL variable set in settings.py:

  STATIC_URL = '/static/'
  

• Add an entry to my project’s base urls.py:

  # static files w/ no-cache headers
  url(r'^static/(?P<path>.*)$', 'django.views.static.serve',
      {'document_root': settings.STATIC_ROOT}),
  

Note that I’m also setting the Cache-Control headers in a middleware class nocache.py:

class NoCache(object):
    def process_response(self, request, response):
        """
        set the "Cache-Control" header to "must-revalidate, no-cache"
        """
        if request.path.startswith('/static/'):
            response['Cache-Control'] = 'must-revalidate, no-cache'
        return response

And then including that in settings.py:

if DEBUG:
    MIDDLEWARE_CLASSES = (
        'django.middleware.common.CommonMiddleware',
        'django.contrib.sessions.middleware.SessionMiddleware',
        'django.middleware.csrf.CsrfViewMiddleware',
        'django.contrib.auth.middleware.AuthenticationMiddleware',
        'django.contrib.messages.middleware.MessageMiddleware',
        'nocache.NoCache',
    )
