Automatic ransack configuration for table backend

[mpapis]

I'm using rails with activeadmin, I want to be able to filter using all translations:

filter :translations_title_i_cont, as: :string, label: 'Title Search'

To make it work I've had to make a bit of magic in application_record.rb:

class ApplicationRecord < ActiveRecord::Base
  extend Mobility

  self.abstract_class = true

  class << self
    alias mobility_translates translates

    def translates(*attributes, **options)
      mobility_translates(*attributes, **options)
      translation_class = const_get(:Translation)
      translation_class.define_singleton_method(:ransackable_attributes) do |_arg = nil|
        attributes.map(&:to_s)
      end
      translation_class.define_singleton_method(:ransackable_associations) do |_arg = nil|
        []
      end
    end
  end
end

Would it be possible for this gem to define those two methods automatically?
