如何在Ruby中的自定义方法中添加url_for

Question

I am writing a custom form helper and i need a URL path declared in routes but i have this error:

    module CustomFormHelpers
      include ActionView::Helpers::TagHelper
      include ActionView::Helpers::FormTagHelper
      include ActionView::Helpers::FormOptionsHelper
      include ActionView::Helpers::CaptureHelper
      include ActionView::Helpers::AssetTagHelper
      include ActionView::Helpers::RawOutputHelper
      include ActionView::Helpers::JavaScriptHelper
      include ActionView::Helpers::UrlHelper

      def tags
        tags_path
      end

    end

in routes.rb

resources :tags

What do I need include in the module to work
