我有一个带有“患者”的 rails 3.2.2 应用程序，他们可以有多种类型的“约会”。所以我做了以下路线：

# config/routes.rb
resources :patients do
  namespace :appointments do
    resources :default, :except => [:index]                                           
    resources :pilates, :except => [:index]
  end
end

相关rake routes输出：

patient_appointments_default_index POST   /patients/:patient_id/appointments/default(.:format)          appointments/default#create
  new_patient_appointments_default GET    /patients/:patient_id/appointments/default/new(.:format)      appointments/default#new
 edit_patient_appointments_default GET    /patients/:patient_id/appointments/default/:id/edit(.:format) appointments/default#edit
      patient_appointments_default GET    /patients/:patient_id/appointments/default/:id(.:format)      appointments/default#show
                                   PUT    /patients/:patient_id/appointments/default/:id(.:format)      appointments/default#update
                                   DELETE /patients/:patient_id/appointments/default/:id(.:format)      appointments/default#destroy
patient_appointments_pilates_index POST   /patients/:patient_id/appointments/pilates(.:format)          appointments/pilates#create
  new_patient_appointments_pilates GET    /patients/:patient_id/appointments/pilates/new(.:format)      appointments/pilates#new
 edit_patient_appointments_pilates GET    /patients/:patient_id/appointments/pilates/:id/edit(.:format) appointments/pilates#edit
      patient_appointments_pilates GET    /patients/:patient_id/appointments/pilates/:id(.:format)      appointments/pilates#show
                                   PUT    /patients/:patient_id/appointments/pilates/:id(.:format)      appointments/pilates#update
                                   DELETE /patients/:patient_id/appointments/pilates/:id(.:format)      appointments/pilates#destroy

请注意，我必须在 rails 变形器上添加 make “default” 和 “pilates” 不可数；否则我得到一些名为“defaults”的路线和其他名为“pilate”的路线：

#config/initialize/inflections.rb
ActiveSupport::Inflector.inflections do |inflect|
  inflect.uncountable %w( default pilates )
end

我的问题是我在“显示”操作中解决的任何“新”操作链接。例如，这个：

link_to "Add", new_patient_appointments_default_path(@patient)

产生这个（有效的，恕我直言）网址：

/patients/14/appointments/default/new

但是当我点击它时，我得到了这个错误：

Started GET "/patients/14/appointments/default/new" for 127.0.0.1 at 2012-06-18 11:29:31 +0200
Processing by Appointments::DefaultController#new as HTML

  Patient Load (0.2ms)  SELECT "patients".* FROM "patients" WHERE "patients"."id" = ? LIMIT 1  [["id", "14"]]
  ...
Completed 500 Internal Server Error in 512ms

ActionController::RoutingError (No route matches {
  :action => "show",
  :controller => "appointments/default",
  :patient_id => #<Patient id: 14, ...>,
  :id => #<Appointments::Default id: nil, ...>})

我已经检查了明显的东西；@patient 对象不是 nil，没有“批量分配问题”，也不是权限问题。控制器没有收到“新”动作，然后检测到错误并重定向到“显示”或类似的东西。

确实似乎该 url 被错误地解析了。

我已经为此投入了几个小时。如果有人对如何解决它有任何指示，我将不胜感激。

我很抱歉。

我尝试为“新”操作渲染一个简单的“纯文本”视图，它起作用了。所以现在我认为这是“新”观点的错误。我仍然不知道为什么 Rails 试图呈现“显示”视图而不是告诉我错误。但我想我可以从这里工作。只要允许我就会关闭这个答案。
