ActsAsList
==========

This acts_as extension provides the capabilities for sorting and reordering a number of objects in a list. The class that has this specified needs to have a +position+ column defined as an integer on the mapped database table.


Example
=======

class TodoList < ActiveRecord::Base
has_many :todo_items, :order => "position"
end

class TodoItem < ActiveRecord::Base
belongs_to :todo_list
acts_as_list :scope => :todo_list
end

todo_list.first.move_to_bottom
todo_list.last.move_higher
