AttributeError: 'Settings' object has no attribute '__file__'

[Thomas Güttler]

Sometimes you have no clue which settings file is active.

For other files I use this pattern, to see which actual file is loaded:

assert 0, mylib.__file__

Unfortunately this does not work for django.conf.settings:

AttributeError: 'Settings' object has no attribute '__file__'

It would be super cool, if this attribute would be available.

Of course I could use:

        assert 0, os.environ['DJANGO_SETTINGS_MODULE']

But sometimes the env var is not the actual file.
