ruby-on-rails – 如果config.cache_classes = true,Rails找不到该模块

概述我有一个宝石,通过routes.rb&的Gemfile.以下是重要的部分： 应用程序的Gemfile source 'https://rubygems.org'gem 'rails', '3.2.9'gem 'mysql2'group :assets do gem 'sass-rails' gem 'coffee-rails'endgem 'jquery-rails'ge 我有一个宝石,通过routes.rb&的Gemfile.以下是重要的部分：

应用程序的Gemfile

source 'https://rubygems.org'gem 'rails','3.2.9'gem 'MysqL2'group :assets do  gem 'sass-rails'  gem 'coffee-rails'endgem 'jquery-rails'gem "common_clIEnt",path: "../common-clIEnt"

App的routes.rb

mount CommonClIEnt::Engine => "",:as => 'shared'

gem的路线.rb

get '/register' => 'session#new_registration'

gems的SessionController

require 'common_clIEnt/session_controller_base'class SessionController < ApplicationController  include CommonClIEnt::SessionControllerBaseend

gems的SessionControllerBase

module CommonClIEnt  module SessionControllerBase  def new_registration      #some code goes here  endend

这在开发和工作中都很好用. rails能够找到CommonClIEnt :: SessionController&每当访问者点击/注册路由时执行new_registration *** 作.但在生产中,rails无法找到CommonClIEnt :: SessionController&生成以下错误：

现在,
这是有趣的部分.这些错误在生产中消失了.当我在production.rb中禁用代码缓存时,app工作得很好.通过设置

config.cache_classes = false

这一切让我想知道,

>为什么rails可以在开发环境中使用CommonClIEnt :: SessionController而不能在生产环境中使用？
>如何设置config.cache_classes = false使其在生产中工作？ rails可以找到它之前无法做到的CommonClIEnt :: SessionController
>我需要做的是让rails找到CommonClIEnt :: SessionController而不是丑陋的黑客攻击禁用代码缓存&在每个请求上重新加载所有代码？

最后,我尽力解释,但仍然有些不清楚,或者需要更多信息.请发表评论.谢谢

解决方法 尝试更新routes.rb,如：

require 'common_clIEnt'mount CommonClIEnt::Engine => '/shared'
