Question

我正在将一个在heroku cedar-10上的旧项目升级到cedar-14并准备让它正常工作我不得不升级一些东西。

将refinerycms从1.0.8升级到1.0.11时，在进入炼油厂/图像区域时出现此错误;

undefined method `escape_path' for Rack::Utils:Module

更新

我尝试更新机架但是rails 3.0.20依赖于机架1.2.5，机架1.2.5不包含escape_path方法！

现在我想知道修补机架或升级到rails 3.1是否容易更新到rails 3.1虽然似乎需要更新refinerycms及其所有朋友。不像听起来那么有趣。

您可以使用缺少的方法扩展旧的Rack::Utils模块。

require 'rack/utils'

module Rack
  module Utils
    def escape_path(s)
      escape(s).gsub('+', '%20')
    end
    module_function :escape_path
  end
end

将其添加到config/initializers到名为expand_rack.rb的文件，例如

对于Rack :: Utils：Module，refinerycms undefined方法`escape_path'
