Using paper_trail to combine act_as_taggable_on associations

I am working on a bug on a rails engine using both paper_trail and act_as_taggable_on. When I roll back a deleted event, the event information is restored but the tags are missing. Has anyone faced this problem?

Some relevant information:

models / calagaor / event.rb

class Event < ActiveRecord::Base
  has_paper_trail
  acts_as_taggable 
end

      

        
        
        
      

    

I also created config / initializers / act_as_taggable.rb file:

ActsAsTaggableOn::Tag.class_eval do
  has_paper_trail
end

ActsAsTaggableOn::Tagging.class_eval do
  has_paper_trail
end 

      

        
        
        
      

    

I am new to rails, so not sure if I will go back in the right direction or not. Let me know if you need more details. Thank!

Edit:

Controllers / calagator / versions_controller.rb

module Calagator

class VersionsController < Calagator::ApplicationController
  def edit
    @version = PaperTrail::Version.find(params[:id])
    @record = @version.next.try(:reify) || @version.item ||    @version.reify

    singular =    @record.class.name.singularize.underscore.split("/").last
    plural = @record.class.name.pluralize.underscore.split("/").last
    self.instance_variable_set("@#{singular}", @record)

    if request.xhr?
      render :partial => "calagator/#{plural}/form", :locals => {   singular.to_sym =>  @record }
    else
      render "calagator/#{plural}/edit", :locals => { singular.to_sym =>  @record }
    end
  end
end

end

      

        
        
        
      

    

I am using paper_trail '3.0.8'
