我試圖創建一個Rails應用程序,它按組和子組劃分用戶,併爲每個子組提供一個自定義的站點。我想做到這一點的最簡單的方法是用命名的參數創建範圍:Rails 3:命名參數路由中斷link_to
scope ":group/:subgroup/" do
devise_for :users
resources :users
end
「回扣路線」,那麼產生這樣的:
users GET /:group/:subgroup/users(.:format) {:action=>"index", :controller=>"users"}
POST /:group/:subgroup/users(.:format) {:action=>"create", :controller=>"users"}
new_user GET /:group/:subgroup/users/new(.:format) {:action=>"new", :controller=>"users"}
edit_user GET /:group/:subgroup/users/:id/edit(.:format) {:action=>"edit", :controller=>"users"}
user GET /:group/:subgroup/users/:id(.:format) {:action=>"show", :controller=>"users"}
PUT /:group/:subgroup/users/:id(.:format) {:action=>"update", :controller=>"users"}
DELETE /:group/:subgroup/users/:id(.:format) {:action=>"destroy", :controller=>"users"}
它完美 - 除了當我使用的link_to:
link_to current_user.name, current_user
然後拋出這個錯誤
ActionController::RoutingError in Users#index
Showing C:/Rails/MyApp/app/views/users/_my_list.html.haml where line #8 raised:

第8行當然是我嘗試使用link_to的地方。我的猜測是,link_to忽略了範圍,它將current_user填充到:group參數中。有沒有辦法阻止這種情況發生,或者我是否完全錯誤地解決了這個問題?
