How can I tell whether my Django application is running on development server or not?

Question

How can I be certain that my application is running on development server or not? I suppose I could check value of settings.DEBUG and assume if DEBUG

Answer 1

I put the following in my settings.py to distinguish between the standard dev server and production:

import sys
RUNNING_DEVSERVER = (len(sys.argv) > 1 and sys.argv[1] == 'runserver')

This also relies on convention, however.
