When I change it to "Tutorial.next_lesson" it then says: undefined method `nil_class_path'
Is this because I have to "pass in the tutorial_id and category_id" or is it a different problem? As for acts_as_list, I would prefer not to use it for now and just keep with using position; However it is something I will be looking at for future projects..
