  1 +ActsAsList
  2 +==========
  3 +
  4 +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.
  5 +
  6 +
  7 +Example
  8 +=======
  9 +
  10 + class TodoList < ActiveRecord::Base
  11 + has_many :todo_items, :order => "position"
  12 + end
  13 +
  14 + class TodoItem < ActiveRecord::Base
  15 + belongs_to :todo_list
  16 + acts_as_list :scope => :todo_list
  17 + end
  18 +
  19 + todo_list.first.move_to_bottom
  20 + todo_list.last.move_higher
