Django: how to get stack traces for runtime warnings
From the docs at: https://docs.djangoproject.com/en/1.10/topics/i18n/timezones/#code
During development, you can turn such warnings into exceptions and get a traceback by adding the following to your settings file:
import warningswarnings.filterwarnings( 'error', r"DateTimeField .* received a naive datetime", RuntimeWarning, r'django\.db\.models\.fields')
You can implement your a log formatter and put trace back for warning messages in the logs using traceback.print_exception().
Refer to Fomatter docs at FormatException

This means that you enabled timezone support in django; but you passed it a datetime object that doesn't have any time zone information attached to it.
If you want django's timezone support, then datetime objects used should be timezone aware.
The documentation on timezone support provides a way to turn your datetime objects into those with timzeones.
