Ok, now my python newbness is going to show...
I figured out what was causing it. (but I don't know why it wasn't working
before)
I can do the following:
request.session['question_list'].append(question.id)
but not:
request.session['question_list'] = request.session['question_list'].append(
question.id)
at least it seems to work now. Also, just to note, this is without setting
the session save every request or explicitly stating that the session has
been modified. I'm going to continue to play with it and if it does break
I'll report but it seems to be working well so far.
