• BrandyMint [github.com/BrandyMint]

• Add member actions with one method call

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

• Integrates with awesome_nested_set

You need active_admin and awesome_nested_set.

Add it to your gemfile:

gem 'active_admin-awesome_nested_set'

Install your bundle:

> bundle install

Assuming you have a Category model:

class Category < ActiveRecord::Base
  # awesome nested set
  acts_as_nested_set
  default_scope :order => 'lft ASC'

  #...
end

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

#app/admin/category.rb
ActiveAdmin.register Category do
  # Sort categories by left asc
  config.sort_order = 'lft_asc'

  # Add member actions for positioning.
  sortable_tree_member_actions

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

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