Rails日志太冗长了

Question

如何防止Rails记录太多？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,但我不希望它在我的生产环境中.

Answer 1

在Rails 4中,将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,你必须修补ActionView:

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

Answer 2

你需要以config.log_level不同的方式设置.了解日志级别.

例如,添加以下内容 config/evironments/production.rb

config.log_level = :warn

您的可能设置为:debug或:info.
