如何向rails记录器添加类名和方法

class CustomLogger < ActiveSupport::Logger
  def format_message(severity, timestamp, progname, msg)
    # 获取当前调用栈的第二层，即调用Logger的类和方法
    caller_info = caller[1].split(":")
    class_name = caller_info[0].split("/").last
    method_name = caller_info[1]

    # 格式化日志信息，添加类名和方法名
    "#{timestamp.to_formatted_s(:db)} #{severity} [#{class_name}##{method_name}] #{msg}\n"
  end
end

config.logger = CustomLogger.new(STDOUT)
