I usually add "import wingdbstub" to the code I'm trying to debug from a 
command line invocation.  Details of how to do this are in the manual:


Motivated by Django and other things like it we want to add multiple 
debug configurations per file so once that's there you could set it up 
in the IDE as another debug configuration for manage.py.  That's on my 
nearer term list.

The work-around for now is to use wingdbstub.  Incidentally you could 
add some code like this to manage.py:

if '--debug' in sys.argv:
  import wingdbstub

Then you can debug any manage.py call from the command line by adding 
--debug arg.

I didn't understand why you had to edit with Notepad.  You should be 
able to edit the args in the Run Arguments field under the Debug tab in 
the File Properties for manage.py.
