Rails 3.0 version of acts_as_list

Sortifiable

This gem provides an acts_as_list compatible capability 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.

This gem requires ActiveRecord 3.0 as it has been refactored to use the scope methods and query interface introduced with Ruby on Rails 3.0

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
