how do I get django runserver to show me DeprecationWarnings and other useful messages?

Question

I've recently updated my django installation from 1.2 to 1.3. On my developer system I didn't get any warnings about deprecated calls. But once I moved the code onto my production apache server, I saw many 'DeprecationWarning' messages in my apache logs. So how do I have to call runserver to these these messages too?

Currently I call it like this:

python manage.py runserver --verbosity 2

Answer 1

Python 2.7 disables the display of DeprecationWarning by default

To re-enable it, set environment variable PYTHONWARNINGS to "d":

export PYTHONWARNINGS="d"; ./manage.py runserver
