我正在尝试使用 papertrail 将模型的更改事件记录在单独的数据库中。

我正在使用 Rails 4.1.2

红宝石2.1

纸迹 4.0.0

下面是我在关注中添加的代码

module Foo
  class Base < ActiveRecord::Base
  end

 class Version < Base
  include PaperTrail::VersionConcern
 end

 class Topic < Base
   has_paper_trail class_name: 'Foo::Version'
 end
end
Foo::Base.establish_connection(:trail_development)

我已将这个 Foo 包含在 topic.rb 中

class Topic < ActiveRecord::Base
  include Foo
end

当我尝试创建、编辑或删除主题时，这不起作用。

我在烧瓶应用中使用芹菜,但芹菜(3.1.8).这是我的烧瓶应用配置

celery.py

 from __future__ import absolute_import
 from celery import Celery
 from cuewords.settings import CELERY_BROKER_URL,CELERY_RESULT_BACKEND

 app = Celery('proj',
         broker=CELERY_BROKER_URL,
         backend=CELERY_RESULT_BACKEND)

app.conf.update(CELERY_TASK_RESULT_EXPIRES=3600)

if __name__ == '__main__':
   app.start()

setting.py

  CELERY_BROKER_URL='redis://localhost:6379/0'
  CELERY_RESULT_BACKEND='redis://localhost:6379/0'
  BROKER_TRANSPORT = 'redis'

api.py

 class Webcontent(Resource):
   def post(self,session=session):
   args = self.parser.parse_args()
   site_url = args["url"]
   url_present=Websitecontent.site_url_present(session,site_url)
    if site_url.strip() != "" and not url_present:
      try:
        #add data and commit 
        session.commit()
        websitecontent=Websitecontent(params*)
        websitecontent.update_url(id,session)
      except:
        session.rollback()
      raise
      finally:
        session.close()                
    else:
      return "No data created / data already present"

在我的模型中,我正在添加一个方法来完成任务

model.py

  from cuewords.celery import app
  class Websitecontent(Base): …

我正在编写一个脚本来从 Rails 项目的 gemfile 中获取所有 gem。脚本是这样的

     @gem_file_path=File.expand_path('../Gemfile', __FILE__) || ENV['BUNDLE_GEMFILE']      ||  Dir.pwd + "/Gemfile"
     File.open(gem_file_path).read.each_line do |i|
 i=i.split
      if i[0] == "gem" && i[0].start_with?("gem")
        name = i[1].gsub(",","") 
        gem_name= eval name
        author_email_id=Gem::Specification.find_by_name(gem_name.to_s).email
        author_name=Gem::Specification.find_by_name(gem_name).author
      end
     end

有更好的方法吗？因为当 gemfile 和其他可能性中提到类似下面的内容时，我也会遇到问题

        gem 'rspec-rails',:group => [:test,:development]

谢谢
