Add sortable columns for active admin.

• Add member actions with one method call

• Add sorting columns in your index views with one method call.

• Integrates with acts_as_list

You need active_admin and acts_as_list.

Add it to your gemfile:

gem 'active_admin-acts_as_list'

Install your bundle:

> bundle install

Assuming you have a Players model:

class Player < ActiveRecord::Base
  # acts as list
  acts_as_list
  default_scope :order => 'position ASC'

  #...
end

You can add sortable columns, member actions and sorting like this:

#app/admin/players.rb
ActiveAdmin.register Player do
  # Sort players by position
  config.sort_order = 'position'

  # Add member actions for positioning.
  sortable_member_actions

  index do
    # This adds columns for moving up, down, top and bottom.
    sortable_columns

    #...
    column :firstname
    column :lastname
    default_actions
  end
end

• Tests, tests, tests.

• Better docs.
