Rails 日志过于冗长 [英] Rails log too verbose

问题描述

如何防止 Rails 日志过多?这是我的 production.log 文件中的一个典型跟踪，很多部分，缓存命中...它在开发中很有用，但我不想在我的生产环境中使用它.

How can I prevent Rails to log too much? Here is a typical trace in my production.log file, many partials, cache hits... It's useful in development but I don't want it in my production environment.

推荐答案

在 Rails 4 中会有一个清理日志的设置:

In Rails 4 there will be a setting to clean up logs:

config.action_view.logger = nil

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

To achieve that in Rails 3, you have to monkey patch ActionView:

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