亲爱的溢出者，
我将尝试给出我的问题的本质。提前感谢您的耐心等待。
我的多态控制器（Appointments）由两个访问Views，第一个属于Admin::Doctor命名空间，第二个属于命名Patient空间。
的相关部分routes.rb：
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
...以及实际路线：
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"}
我的模型：
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 上test/functional/appointments_controller_test.rb，我正在测试patients没有错误，但是在测试时doctors，我得到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 < ActionController::TestCase
fixtures :patients, :appointments, :doctors, :users
# The following passes:
def setup
login_as :admin
end
test "should show patient appointment" do
get :show, :id => 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.
test/functional/admin/appointments_controller_test.rb
class Admin::AppointmentsControllerTest < ActionController::TestCase
fixtures :patients, :appointments, :doctors, :users
# The following passes:
def setup
login_as :admin
end
test "should show doctor appointment" do
get :show, :id => 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'
至此，我@controller = AppointmentsController.new在setup方法下添加了，才弄的很熟悉：
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，这就像一个恶性循环。
编辑结束
所以，由于测试找不到控制器，因为它的路由指向admin/appointments
- 为什么我能够渲染
/admin/doctors/1/appointments，因为appointments_controller.rb它既不在Admin文件夹也不在Admin::命名空间下（但路由指向那里）和 - 为这种情况编写功能测试的最佳策略是什么？
先感谢您！
