Sorting of translated column leads to an exception about activeadmin-globalize HOT 1 CLOSED

The Active Admin Docs cover this issue:

Associated Sorting

You’re normally able to sort columns alphabetically, but by default you can’t sort by associated objects. Though with a few simple changes, you can.

Assuming you’re on the Books index page, and Book has_one Publisher:

controller do
  def scoped_collection
    resource_class.includes(:publisher) # prevents N+1 queries to your database
  end
end

Then it’s simple to sort by any Publisher attribute from within the index table:

 index do
   column :publisher, sortable: 'publishers.name'
 end

from activeadmin-globalize.
