Great! Thanks a lot, it worked!
Here's a little function that I made and that is quite helpful:
def get_class(class_path):
i = class_path.rfind('.')
module_path, class_name = class_path[:i], class_path[i+1:]
module = __import__(module_path, globals(), locals(),
[class_name])
return getattr(module, class_name)
Thanks again for your help. That wasn't easy, but that made me visit
some parts of Python and Django that I didn't know about. And it does
demystify a lot of things!
