ruby-on-rails - 奇怪的事件管理员(Rails)错误

Question

这是迄今为止我遇到的最荒谬的错误之一。我登录到事件管理员并在我的屏幕上获取任何事件管理页面的信息:

(?i-mx:)

我查看了服务器日志，好像登录成功了，服务器计算了所有列的查询，但最终输出如上!我正在使用 ruby​​ 1.9.3、rails 3.1.3 和事件管理版本 0.4.4。

以下是其中一个页面加载的示例日志输出:

我通过查看 mini-profiler docs 找到了一种更简洁的方法来处理这个问题。并查看 config class 中的可用配置选项

在 config/initializers/mini_profiler.rb

Rack::MiniProfiler.config.skip_paths << '/admin' #or whatever you namespace active_admin under

旁注，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?}
