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。

PS：我正在使用Rails 3.2.6
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 。 了解日志级别 。
例如，将以下内容添加到config/evironments/production.rb
config.log_level = :warn
你的可能设置为:debug或:info 。
我把它放在我的初始化器中monkeypatch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
