Forum: Ruby on Rails [Rails 3.2] How to extend a gem model

I am using the gem  'acts-as-taggable-on' ( mbleigh) and I need to 
extend
the Tag model to  translate the tag name with Globalize
How can I add  "translates :name" into ActsAsTaggableOn::Tag ?  I can 
fork
the gem and modify my version, but is there any way to do it simply with
"extend ActiveSupport::Concern"  ?

currently :

module ActsAsTaggableOn
  class Tag < ::ActiveRecord::Base
    include ActsAsTaggableOn::Utils

    attr_accessible :name

needed :

module ActsAsTaggableOn
  class Tag < ::ActiveRecord::Base
    include ActsAsTaggableOn::Utils

    attr_accessible :name
translate :name

You can decorate the class:

ActsAsTaggableOn::Tag.class_eval do
   translate :name
end
