module Component
# Usage:
#
# # app/models/gallery.rb
# class Picture < ActiveRecord::Base
# has_many :pictures, -> { order(position: :asc) }
# # ...
# end
#
# # app/models/picture.rb
# class Picture < ActiveRecord::Base
# acts_as_list scope: :gallery
# # ...
# end
#
# # app/galleries/index.html.haml
# = collection_table(collection: @pictures) do |table|
# = table.acts_as_list_actions scope: :gallery_id
#
# You will have to add a repositioning route to your resource:
#
# # config/routes.rb:
# Rails.application.routes do
# resources :picture do
# post :reposition, on: :member
# end
# # ...
# end
#
# Additionally you will need a controller action to handle the reponsitioning.
# Include Rao::ResourcesController::ActsAsListConcern from rao-resource_controller
# if you don't want to implement it yourself:
#
# # app/controllers/pictures_controller.rb
# class PicturesController < ApplicationController
# include Rao::ResourcesController::ActsAsListConcern
# # ...
# end
#
