You can try this:

from django.db.models.signals import post_save

def logging_function(sender, **kwargs):
   # do your logging

post_save.connect(logging_function)

Python has a logger http://docs.python.org/library/logging.html What's wrong with that?

You can, also, add an event table to your Django models and write to that table.

For real fun, you can create a decorator which writes to that table.

You can search, too. You'll find things like this: http://djangosnippets.org/snippets/2111/
