如何在Rails 2.3中测试多态控制器？
亲爱的花花公子，
我会尽力说明问题的实质。 提前感谢您的耐心等待。
My Polymorphic Controller（ Appointments ）由两个Views ，第一个属于Admin::Doctor命名空间，第二个属于Patient命名空间。
routes.rb的相关部分：
map.resources :patient do |patients| patients.resources :appointments end map.namespace(:admin) do |admin| admin.resources :doctor do |doctors| doctors.resources :appointments end end
所以，我现在可以得到：
patients/:patient_id/appointments admin/doctors/:doctor_id/appointments
……和实际路线：
rake routes | grep appointment
new_patient_appointments GET /patients/:patient_id/appointments/new(.:format) {:controller=>"appointments", :action=>"new"} edit_patient_appointments GET /patients/:patient_id/appointments/edit(.:format) {:controller=>"appointments", :action=>"edit"} patient_appointments GET /patients/:patient_id/appointments(.:format) {:controller=>"appointments", :action=>"show"} PUT /patients/:patient_id/appointments(.:format) {:controller=>"appointments", :action=>"update"} DELETE /patients/:patient_id/appointments(.:format) {:controller=>"appointments", :action=>"destroy"} POST /patients/:patient_id/appointments(.:format) {:controller=>"appointments", :action=>"create"} new_admin_doctor_appointments GET /admin/doctors/:doctor_id/appointments/new(.:format) {:controller=>"admin/appointments", :action=>"new"} edit_admin_doctor_appointments GET /admin/doctors/:doctor_id/appointments/edit(.:format){:controller=>"admin/appointments", :action=>"edit"} admin_doctor_appointments GET /admin/doctors/:doctor_id/appointments(.:format) {:controller=>"admin/appointments", :action=>"show"} PUT /admin/doctors/:doctor_id/appointments(.:format) {:controller=>"admin/appointments", :action=>"update"} DELETE /admin/doctors/:doctor_id/appointments(.:format) {:controller=>"admin/appointments", :action=>"destroy"} POST /admin/doctors/:doctor_id/appointments(.:format) {:controller=>"admin/appointments", :action=>"create"}
我的模特：
class Patient has_many :appointments, :as => :attendee end class Doctor has_many :appointments, :as => :attendee end class Appointment belongs_to :attendee, :polymorphic => true end
我的控制器：
Controllers/Admin/doctors_controller.rb
class Admin::DoctorsController < AuthorisedController end
Controllers/appointments_controller.rb
class AppointmentsController < ApplicationController end
Controllers/patients_controller.rb
class PatientsController < ApplicationController end
在我的test/functional/appointments_controller_test.rb ，我正在测试patients没有错误，但在测试doctors ，我得到一个ActionController::RoutingError ：
4) Error: test_should_show_doctor_appointment(AppointmentsControllerTest): ActionController::RoutingError: No route matches {:controller=>"appointments", :id=>"281110143", :action=>"show", :doctor_id=>2} test/functional/appointments_controller_test.rb:55:in `test_should_show_doctor_appointment'
编辑：
测试中的相关部分：
test/functional/appointments_controller_test.rb
require 'test_helper' class AppointmentsControllerTest patients(:one).to_param, :appointment_id => appointments(:app_one).id assert_response :success end # The following fails, giving the error mentioned above: test "should show doctor appointment" do get :show, :id => doctors(:one).to_param, :appointment_id => appointments(:app_one).id assert_response :success end end
正如@Ryan指出的那样，测试位于基本命名空间下，因此下一步，我在Admin下创建了一个测试。
test/functional/admin/appointments_controller_test.rb
class Admin::AppointmentsControllerTest doctors(:one).to_param, :appointment_id => appointments(:app_one).id assert_response :success end end
…现在我收到此错误：
1) Error: test_should_show_doctor_appointment(Admin::AppointmentsControllerTest): RuntimeError: @controller is nil: make sure you set it in your test's setup method. test/functional/admin/appointments_controller_test.rb:13:in `test_should_show_doctor_appointment'
此时，我在setup方法下添加了@controller = AppointmentsController.new ，只是为了得到非常熟悉的：
1) Error: test_should_show_doctor_appointments(Admin::AppointmentsControllerTest): ActionController::RoutingError: No route matches {:action=>"show", :controller=>"appointments", :doctor_id=>2, :id=>"281110143"} test/functional/admin/appointments_controller_test.rb:14:in `test_should_show_doctor_appointments'
在我看来，这似乎是一个恶性循环。
编辑结束
因此，由于测试无法找到控制器，因为其路径指向admin/appointments
- 为什么我能够渲染
/admin/doctors/1/appointments因为appointments_controller.rb既没有在Admin文件夹下也没有Admin::namespace（但路由指向那里）和 - 为该案例编写function测试的最佳策略是什么？
先感谢您！
的pR
这个错误：
ActionController::RoutingError: No route matches {:controller=>"appointments", :id=>"281110143", :action=>"show", :doctor_id=>2}
显示您正在向名为AppointmentsController的控制器发出请求，但是根据您的路线判断：
new_admin_doctor_appointments GET /admin/doctors/:doctor_id/appointments/new(.:format) {:controller=>"admin/appointments", :action=>"new"} edit_admin_doctor_appointments GET /admin/doctors/:doctor_id/appointments/edit(.:format){:controller=>"admin/appointments", :action=>"edit"} admin_doctor_appointments GET /admin/doctors/:doctor_id/appointments(.:format) {:controller=>"admin/appointments", :action=>"show"} PUT /admin/doctors/:doctor_id/appointments(.:format) {:controller=>"admin/appointments", :action=>"update"} DELETE /admin/doctors/:doctor_id/appointments(.:format) {:controller=>"admin/appointments", :action=>"destroy"} POST /admin/doctors/:doctor_id/appointments(.:format) {:controller=>"admin/appointments", :action=>"create"}
该路由仅在admin命名空间内可用，即Admin::AppointmentsController 。
我敢打赌，你正在做类似describe AppointmentsController事情，而不是describe Admin::AppointmentsController 。 我不确定，因为你没有包括测试本身的关键部分。
