这是迄今为止我遇到的最荒谬的错误之一。我登录到活动管理员，并在我的屏幕上显示任何活动的管理页面：
（I-MX：＆LT; /体＆GT）
我检查了服务器日志，我似乎成功登录，服务器计算所有列的查询，但最终输出是上面的！我正在使用 ruby 1.9.3，rails 3.1.3和活动管理版0.4.4 。
以下是其中一个页面加载的示例日志输出：

通过查看mini-profiler docs并查看config class
中的可用配置选项，我找到了一种更清晰的方法来处理此问题在config/initializers/mini_profiler.rb
Rack::MiniProfiler.config.skip_paths << '/admin' #or whatever you namespace active_admin under
注意，还有一些其他有用的配置设置：
Rack::MiniProfiler.config.use_existing_jquery = true
Rack::MiniProfiler.config.pre_authorize_cb = lambda {|env| Rails.env.development?}

解决了它..这是我的宝石的问题，即机架迷你剖面仪。调试此问题非常痛苦，因为没有任何特定的错误消息。我恢复了之前的提交，不得不痛苦地查看所有更改以找到这个!!
