Well, does your lesson.models file definitely define a class called Lesson? This is why it's a bad idea to do from x import *. You should always import the things you need explicitly, then you can tell what's going wrong. Try doing from schoolutil.lesson.models import Lesson and see if it still goes wrong - or if you get a more informative error message. -- DR. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
