You definitely need to pass in the values of tutorial_id - that class method isn't going to be stealing instance variables out of the controller or anything like that. Personally I'd have next_lesson be an instance method of tutorial
link_to 'Next', @tutorial.next_lesson sounds nicer than link_to 'Next', Tutorial.next_lesson(@tutorial.id, @tutorial.category_id) or anything like that.
