Question

我正在设计用于在用户模型上具有单表继承的rails 4应用程序。我们有7个不同类别的用户，每个用户都有自己的ActiveRecord模型，该模型继承自基础User模型。

我已经完成了我在网络上可以找到的内容，但是我在设置正确的测试时遇到了很多奇怪的问题。我编写了一个自定义sessions_controller来确定哪些类型的用户正在尝试登录并签入正确的资源类，我写了一个小规范来验证它是否正常工作，同时我将其余的功能启动并运行。我似乎无法获得正确的方法来设计使用rspec。我第一次遇到错误：

Failure/Error: post :create, user: { email: 'fake@address.com' }
NoMethodError:
   undefined method `authenticate?' for nil:NilClass

这很奇怪，因为我在我的规范帮助文件中包含了devise和warden测试助手（粘贴在下面）。当我在SessionsController规范中直接包含Devise :: TestHelpers时，我得到了一个不同的错误：

1) SessionsController POST create works
   Failure/Error: post :create, user: { email: 'fake@address.com' }
   ArgumentError:
     uncaught throw :warden
   # ./app/controllers/sessions_controller.rb:5:in 'create'
   # ./spec/controllers/sessions_controller_spec.rb:17:in 'block (3 levels) in <top (required)>'

我已经完成了大量的谷歌搜索，并且只找到了关于将specise和warden测试助手添加到spec文件或在@ request.env上设置“devise.mapping”的建议（两者都是我已经完成的）。任何和所有的帮助将不胜感激，尤其是指向我未见过的网络教程的指针;）。我看过这些页面：

这是我的sessions_controller.rb：

class SessionsController < Devise::SessionsController
  class UnrecognizedUserTypeError < StandardError; end

  def create
    created = super do
      sign_in(type, user_class.try(:find, resource.id))
    end

    created
  end

  private

  def type
    unless User::TYPES.include(type = resource.type.try(:underscore))
      raise UnrecognizedUserTypeError
    end

    type
  end

  def user_class
    type.try(:constantize)
  end
end

这是我的sessions_controller_spec.rb：

require 'rails_helper'

describe SessionsController do
  # This line should not be needed since it has been included in spec_helper.rb
  # but this spec file doesn't seem to work without it (bl 2014-08-11).
  include Devise::TestHelpers

  before do
    setup_controller_for_warden
    # Since we're bypassing the router in this test, we need to explicitly
    # tell devise which mapping to use.
    @request.env["devise.mapping"] = Devise.mappings[:user]
  end

  describe "POST create" do
    it "works" do
      post :create
      expect(response.code).to eq(200)
    end
  end
end

以下是我的spec_helper.rb中的相关行（rails_helper要求）

RSpec.configure do |config|

  config.include FactoryGirl::Syntax::Methods
  config.include Devise::TestHelpers, type: :controller
  config.include Warden::Test::Helpers

  config.before(:suite) do
    begin
      DatabaseCleaner.start
      FactoryGirl.lint
      Warden.test_mode!
    ensure
      DatabaseCleaner.clean
    end
  end

  config.after(:suite) do
    Warden.test_reset!
  end
...
end

以下是config / routes.rb中的相关行：

Rails.application.routes.draw do
  devise_for :users, controllers: { sessions: 'sessions' }
  devise_for :administrator_users, skip: :sessions
  devise_for :manager_users, skip: :sessions
  devise_for :adjuster_users, skip: :sessions
  devise_for :nurse_case_manager_users, skip: :sessions
  devise_for :technical_assistant_users, skip: :sessions
  devise_for :provider_users, skip: :sessions
  devise_for :super_administrator_users, skip: :sessions
...
end
