This small hack implements has_many friendly Globalize3 helper for ActiveAdmin.

Admittedly it generates structure that jQueryUI tabs() expect. However the whole idea is pretty simple and you should be able to change it to suit your needs.

Installation

Add this line to your application's Gemfile:

gem 'ActiveAdmin-Globalize3-inputs'

And then execute:

$ bundle

Usage by example

ActiveAdmin.register Gallery do
  form do |f|
    f.globalize_inputs :translations do |lf|
      lf.inputs do
        lf.input :title
        lf.input :description

        lf.input :locale, :as => :hidden
      end
    end

    f.has_many :photos do |photo|
      photo.inputs do
        photo.input :image, :as => :file
      end

      photo.globalize_inputs :translations do |lp|
        lp.inputs do
          lp.input :description

          lp.input :locale, :as => :hidden
        end
      end
    end

    f.buttons
  end
end

As you can see, there's no special option for locales. The list is taken from I18n.available_locales, so you'd probably want to define the locales your application works with somewhere.
