Rails日志太冗长了

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。

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

您需要以不同方式设置config.log_level。了解 Log Levels

例如,将以下内容添加到config/evironments/production.rb

config.log_level = :warn

您可能会设置为:debug:info

我把它放在我的初始化器中,以monkeypatch某些日志记录去调试而不是info:

module ActionView
  class LogSubscriber
    def render_template(event)
      message = "Rendered #{from_rails_root(event.payload[:identifier])}"
      message << " within #{from_rails_root(event.payload[:layout])}" if event.payload[:layout]
      message << " (#{event.duration.round(1)}ms)"
      debug(message)
    end
    alias :render_partial :render_template
    alias :render_collection :render_template
  end  
end

module ActionController
  class LogSubscriber
    # Use debug logging for read_fragment
    # %w(write_fragment read_fragment exist_fragment? expire_fragment expire_page write_page).each do |method|
    %w(read_fragment).each do |method|
      class_eval <<-METHOD, __FILE__, __LINE__ + 1
        def #{method}(event)
          return unless logger.info?
          key_or_path = event.payload[:key] || event.payload[:path]
          human_name  = #{method.to_s.humanize.inspect}
          debug("\#{human_name} \#{key_or_path} (\#{event.duration.round(1)}ms)")
        end
      METHOD
    end
  end
end
