Django logging settings
# Logging settings for django projects, works with django 1.5+
# If DEBUG=True, all logs (including django logs) will be
# written to console and to debug_file.
# If DEBUG=False, logs with level INFO or higher will be
# saved to production_file.
# Logging usage:
# import logging
# logger = logging.getLogger(__name__)
# logger.info("Log this message")

For django 1.10+, null handler should be: "class": 'logging.NullHandler',

And another improvement is changing filename to:
'filename': os.path.join(DJANGO_ROOT, 'logs/myfile.log'),

So it is always placed on same folder.
