Rails - Jan 2006 - acts_as_tree & acts_as_list for a single model?

Hi,

If I have a db table

categories
- id
- name
- parent_id
- position

is it alright to have the Category model act_as_tree and for each
level act_as_list?

class Category < ActiveRecord::Base
  acts_as_tree :order => :position
  acts_as_list :scope => :parent_id
end

Thanks,
Peter

Hi, Peter,

yes you could do that. I''m doing it in one of my models without a
problem.

Best Regards
Jan Prill

I had some trouble with this when I tried it. See:
http://forum.textdrive.com/viewtopic.php?id=7639

I still haven''t figured out how to get it to work right. If you get it 
to work, let me know.
