ActiveAdmin Reorderable

Drag and drop to reorder your ActiveAdmin tables.

Requirements

Your resource classes must respond to insert_at ala the acts_as_list API. You don't need to use acts_as_list, but if you don't, make sure to define insert_at.

Installation

• Add gem 'activeadmin_reorderable' to Gemfile
• Add #= require activeadmin_reorderable to app/assets/javascripts/active_admin.js.coffee
• Add @import "activeadmin_reorderable"; as the last @import statement in app/assets/stylesheets/active_admin.css.scss

Use

parts.rb

ActiveAdmin.register Part do
  reorderable # Necessary to support reordering in a subtable within Widget below
end

widgets.rb

ActiveAdmin.register Widget do
  config.sort_order = 'position_asc' # assuming Widget.insert_at modifies the `position` attribute
  config.paginate   = false

  reorderable

  actions :index, :show

  # Reorderable Index Table
  index as: :reorderable_table do
    column :id
    column :name
  end

  show do |widget|
    attributes_table do
      row :id
      row :name
    end

    # Reorderable Subtable
    # Note: you must include `reorderable` in the ActiveAdmin configuration for the resource
    # being sorted. See the `Part` example above this code block.
    reorderable_table_for widget.parts do
      column :name
      column :cost
    end
  end
end
