Impossible to run gunicorn with django-split-settings

[benjaminrigaud]

Running the command :

python manage.py run_gunicorn

Produces the following stack trace:

AttributeError: 'NoneType' object has no attribute 'rfind'

locals()['included_file'] exists but is set to None

A quick fix could be to replace the line (in tools.py):

including_file = scope.get('__included_file__', scope['__file__'])

by

including_file = scope.get('__included_file__') or scope['__file__']

Thanks for the report! Could you try if the above patch fixes this? It's a change I had to make previously in one particular project to make split settings work correctly, and I didn't commit it into this repository since we didn't hit the same issue elsewhere.

Amazing response time :)

Yep, the patch fixes it. Thanks!
