Thanks so much! It works!
However now I'm just trying to get the whole 'next lesson' thing
working.
I've tried it using this code in the model:
def self.next_lesson
find :all, :conditions => ["position > ? AND category_id = ?",
@tutorial_id, @category_id], :order => 'position', :limit => 1
end
and then this code in the link:
<%= link_to 'Next lesson.', @tutorial.next_lesson %>
However I get this error:
undefined method `next_lesson'
Why is this happening? and how do I overcome it?
Thanks for your help,
Joe
