最佳回答

由于其他解决办法尚未奏效,你可以尝试更加艰难。

在最初的提交者档案(如config/ originalizers/url_for_up.rb)中,添加如下内容:

ActionView::Helpers::UrlHelper.class_eval do

  def with_subdomain(subdomain)
    subdomain = (subdomain || "")
    subdomain += "." unless subdomain.empty?
    [subdomain, request.domain, request.port_string].join
  end

  alias_method_chain :url_for, :subdomain

  def url_for_with_subdomain(options = nil)
    if options.kind_of?(Hash) && options.has_key?(:subdomain)
      options[:host] = with_subdomain(options.delete(:subdomain))
    end
    url_for_without_subdomain( options )
  end      

end
问题回答

在您的融合测试中,你可以尝试添加以下文字:

include ActionView::Helpers::UrlHelper

贵题中的代码是确定顶级名称空间的新<代码>UrlHelper模块。 如果你试图在<条码>行动意见:Helpers:UrlHelper中推翻方法,你需要完全限定这一模块:

module ActionView
  module Helpers
    module UrlHelper
      def url_for
        # override as in your question
      end
    end
  end
end

我不敢肯定铁路会完全乐于电线/助动器,因此,你可能需要将铁路放在<条码>lib/action_view/helpers/url_helper.rb。 (如果你从<代码>lib上重载,或你需要在其<代码>上明确要求存档。
