Dynamic Django settings context processor

Here's a nice way of easily passing only certain settings variables to the template. Because of the way Django looks up context processors, we need a little hack with sys.modules.

import sys

from django.conf import settings as django_settings

class SettingsProcessor(object):
    def __getattr__(self, attr):
        if attr == '__file__':
            # autoreload support in dev server
            return __file__
            return lambda request: {attr: getattr(django_settings, attr)}

sys.modules[__name__ + '.settings'] = SettingsProcessor()

Assuming this is placed in a file called utils/context_processors.py, you can use this from the settings.py file like so:

    # ....

Nice and simple.
