ruby-on-rails - 使用 paper_trail 来具体化 acts_as_taggable_on 关联

Question

我正在使用 paper_trail 和 acts_as_taggable_on 解决 Rails 引擎上的错误。当我回滚已删除的事件时，事件详细信息会恢复，但标签不会。有没有人遇到过同样的问题？

一些相关信息:

模型/calagaor/event.rb

class Event < ActiveRecord::Base
  has_paper_trail
  acts_as_taggable 
end

我还创建了一个 config/initializers/act_as_taggable.rb 文件:

ActsAsTaggableOn::Tag.class_eval do
  has_paper_trail
end

ActsAsTaggableOn::Tagging.class_eval do
  has_paper_trail
end 

我是 Rails 的新手，所以我不确定我是否正朝着正确的方向前进。如果您需要更多详细信息，请告诉我。谢谢!

编辑:

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

我正在使用 paper_trail '3.0.8'

Answer 1

[How do I use] paper_trail to reify acts_as_taggable_on associations? I'm using paper_trail '3.0.8'

paper_trail 3 不进行关联。尝试升级到 paper_trail 4。
