我按照Ruby Screencast指南从Rails 3.2升级到Rails 4.我的测试正在运行并且服务器启动,但是当我发送请求时收到错误:

ERROR NoMethodError: undefined method `tagged' for #<Formatter:0x000000057f5dc8>

我已经查看了代码,对我来说没有意义.它叫logger.tagged.变量后面的对象logger不是记录器,而是Formatter对象.这很奇怪.

知道是什么原因引起的吗？到目前为止我:

• 删除了我的 Gemfile.lock
• gem update rails
• bundle install
• bundle update

在这个和不同的订单.我怎么处理这个？

我为 Rails 编写了一个自定义格式化程序：

module Logging\n  class GeneralFormatter < Logger::Formatter\n    def call(severity, time, program_name, message)\n      ...\n    end\n  end\nend\n

根据Rails 指南和这个答案，我所要做的就是使用它

config.log_formatter = Logging::GeneralFormatter.new

不幸的是，这似乎不起作用\xe2\x80\x94我的自定义格式没有启动。但是，如果我也定义它：

module Logging\n  class GeneralLogger < ActiveSupport::Logger\n    def initialize(*args)\n      super(*args)\n      @formatter = GeneralFormatter.new\n    end\n  end\nend\n

然后我就可以按照config.logger = Logging::GeneralLogger.new需要格式化我的日志了。

我的设置做错了什么log_formatter？当我想要的只是自定义格式时，我宁愿不定义自己的记录器。

编辑（回应评论，并通过更多的挖掘添加更多细节）：

我正在设置config.log_formatter并在开发中进行测试，并且它似乎在一定程度上application.rb起作用，因为该调用为我提供了我的自定义类。但这是我在打电话时看到的行为：Rails.logger.formatterRails.logger.warn("test")
