Rails 日志太详细

如何防止 Rails 记录过多日志？这是我的 production.log 文件中的典型跟踪，许多部分，缓存命中...它在开发中很有用，但我不希望在我的生产环境中使用它。

感谢您的帮助

PS：我使用的是Rails 3.2.6

在 Rails 4 中会有一个清理日志的设置：

config.action_view.logger = nil

要在 Rails 3 中实现这一点，您必须对 ActionView 进行猴子修补：

module ActionView
  class LogSubscriber < ActiveSupport::LogSubscriber
    def logger
      @memoized_logger ||= Logger.new('/dev/null')
    end
  end
end
