在猴子中使用autoload_path在Rails 3.1中修补ActionDispatch :: Routing时出错

问题描述

|| 与Gem

tasteful-routes

（https://github.com/icelab/tasteful-routes/blob/master/lib/tasteful_routes/mapper.rb）类似，我希望能够添加一些方法作为路由助手。 我有一个文件“ 1”，其中包含

puts \"In mapper.rb\"
module Actiondispatch::Routing
  class Mapper
    module northStar
      def star(controller)
        puts \"Testing!\"
      end
    end
    include northStar
  end
end

为了自动加载，我在ѭ3中放置了以下内容

config.autoload_paths += Dir[\"#{config.root}/lib/**/\"]

当我尝试运行Rails时，遇到了一个问题。
