如何在不同的命名空间下测试控制器以及为什么此测试失败? [英] How to test Controllers under different namespaces and why this test fails?

问题描述

亲爱的溢出者，

我正在使用 Rails 2.3 并且我创建了一个多态控制器，它可以被属于不同命名空间的视图访问.这是故事，感谢您提前阅读:

I am using Rails 2.3 and I have created a polymorphic Controller which is accessed by Views belonging to different namespaces. Here is the story and thanks for reading it in advance:

我有这些路线:

rake 路线 |grep预约

 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"}

...这些控制器:

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

...以及这些测试:

测试中的相关部分:

test/functional/appointments_conrroller_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 after the code block:

  test "should show doctor appointment" do
    get :show, :id => doctors(:one).to_param, :appointment_id => appointments(:app_one).id
    assert_response :success
  end

end

错误:

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'

该测试在基本命名空间下，因此下一步，我在 Admin 下创建了一个测试.

the test is under the base namespace, so as a next step, I created a test under 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:

...and now I get this error:

 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:

At this point, I added @controller = AppointmentsController.new under the setup method, only to get the very familiar:

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'

这对我来说似乎是一个恶性循环.

It seems like a vicious circle to me.

还是谢谢...

推荐答案

你可能应该这样做:

@controller = Admin::AppointmentsController.new 

否则，您将引用主命名空间内的控制器，而不是 Admin 命名空间.

Otherwise you're referencing the controller inside the main namespace and not the Admin namespace.
