Google App Engine log username with custom auth

I use a custom authentication for my python Go开发者_开发百科ogle App Engine app. There is a "username" field in the log for every request, which is empty now. Is it possible to add the name of the authenticated user to the log? I would not like to add an "user: %s" % user.name manually to all of my logging.xxx statements.

Thanks.

Add a single logging.debug call in your authentication code to log the current user. Logs are shown aggregated by request, so you'll always be able to see the user associated with that request.
