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，但我不希望在我的生产环境中使用它。

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，您必须修改 ActionView：

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

你需要设置你的config.log_level不同。了解日志级别。

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

config.log_level = :warn

您的可能设置为:debug或:info。

我把它放在我的初始化程序中，以猴子补丁某些日志记录去调试而不是信息：

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

在 2021 年，我建议为此使用语义记录器（和rails_semantic_logger）gem。（文档链接）

Lograge也是一种选择，但在这一点上似乎维护得不太好。
