ruby-on-rails – 在生产环境中运行RoR应用程序时出现问题

有一个应用程序有“列表” – 认为分类广告 – 每个列表都有一个标签列表.

我在生产模式下运行应用程序时,以下代码失败,但在开发模式下正常工作

uninitialized constant ActiveRecord::Acts::Taggable::InstanceMethods::TagList
Extracted source (around line #45):

42:         
43:         <span class="listingIndexTags">
44:             Location: [location] | Tags:
45:             <% tag_list = listing.tag_list %>
46:             <% if tag_list != nil %> 
47:                 <% for tag in tag_list %>
48:                     <%= link_to tag.to_s, { :action => "filter_on",

我在这个测试用例中用来启动我的mongrel实例的命令行:
ruby脚本/服务器mongrel -e production

默认为端口3000.我可以访问应用程序中不要调用“listing.tag_list”的其他视图.

“.tag_list”由“acts_as_taggable_on_steroids”提供,我正在此应用中使用.它作为宝石安装.

也许我的环境文件很难?

这是我的development.rb文件

config.cache_classes = false

config.whiny_nils = true

config.action_controller.consider_all_requests_local = true
config.action_view.debug_rjs                         = true
config.action_controller.perform_caching             = false

config.action_mailer.raise_delivery_errors = true

config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
  ...took these settings out for this post...
}

还有我的production.rb文件……

config.cache_classes = true
config.threadsafe!  

config.action_controller.consider_all_requests_local = false
config.action_controller.perform_caching             = true

config.cache_store = :mem_cache_store

config.action_mailer.raise_delivery_errors = false

config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
  ...took these settings out for this post...
}

最佳答案 固定:

好吧,推迟修复这个bug直到我绝对不得不(今天),我终于找到了问题的根源.

包含该行:
config.threadsafe!

在我的“production.rb”文件中导致它.

I finally found it by:
    1. Making my production and development environment files identical
    2. Line-by-line, changing the production environment file until it either:
      a. The app broke in production mode
      b. I was back to my original production file

无论如何,当我添加“config.threadsafe!”时线 – IT BROKE!应用程序休息我真的很高兴.

所以,稍微阅读以了解这个选项究竟是什么,与Mongrel结合(如果Mongrel甚至相关),我会得到答案.
