Django - finding the module where warnings are coming from?

Question

Here's my test output. I can't figure out where the bad DateTimeField is being set, because all I can see is: /home/workspace/ticktockgo/venv/local/lib/python2.7/site-packages/django/db/models/fields/init.py

which isn't very useful at narrowing the problem. How do I get more details on what's causing the warnings? A stacktrace would be nice!

Thanks for any help!

python -W manage.py test

Replace warnings.showwarning with a function that uses traceback to find and display the current stack frame.
