[Rails 3.2] How to extend a gem model

[Erwin]

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

I'm trying to run migration to allow translation of tags with Globalize gem.

I've added config/initializers/acts_as_taggable_on.rb with following content:

ActsAsTaggableOn::Tag.class_eval do
  translates :name
end

Running "bundler exec rake db:migrate" fails with error message:
undefined method `translates' for #<Class:0xba5eea10> (NoMethodError)

Is something I missing here?

Try adding require n include statement
