How do I manage multiple lists?
This is what I need. Sometimes an item needs to be moved from one list
class Item < ActiveRecord::Base
acts_as_list :scope => :group
class Group < ActiveRecord::Base
has_many :items, :order => “position”
Now, sometimes, I may need to change an item from one group to another.
But when I do that, the position number is not corrected. I end up
having multiple items in a group with the same position.
What is the correct way to handle something like this?
Thanks for your help.
