我正在使用设计并尝试在设计注册页面中使用令牌代码，我知道设置链接的路线存在一些问题。链接看起来像这样
http://localhost:3000/users/sign_up.asdfsdfasdffffffffffffffasdfasdf
查询字符串之间有一个点，它不起作用。
我的 routes.rb 是这个
devise_for :users ,:controllers => { :registrations => "registrations" } do
#get "/register", :to => "devise/registrations#new"
get 'users/sign_up/:invitation_token' => "registrations#new", :as => :reg_with_code
end
请帮我设置一个正确的链接，中间的斜线。
这是可能的耙路线
