I've beem working on a simple banking app based on the Django tutorial.
Thanks to your help it almost works now. It was working using templates but
after making some changes to get HttpResponseRedirect to work I changed
what was in the urls file like it shows in the tutorial. Now, the server
doesn't run. It says there's an attribute error. I've temporarily left the
user name and password in at the moment. I had a look at their tutorial how
to do a use the Django authentication system (thanks for telling me about
that) and I'm going to change that after I understand what's going on here.
It's amazing how much you can do with Django. Do you think with time you
get more used to what different errors mean? The errors seem new and
confusing to me at the moment. Any help would be very much appreciated.
Thanks in advnace.
