ruby-on-rails-3 - 使用设计 : could not find valid mapping 进行 RSpec 测试

Question

我正在尝试使用设计 1.3.4 运行 Controller 规范。 (和工厂女孩)
我按照项目的 git wiki 中的说明进行操作。我可以使用在宏中创建的 login_user 方法以用户身份登录，但 login_admin 失败并出现以下错误:

...
sign_in Factory.create(:admin)

Could not find a valid mapping for #<User id: 2023, email: "admin1@gmail.com", .... >

工厂:

Factory.define :user do |f|
  f.sequence(:username) {|n| "user#{n}"}
  f.sequence(:email) {|n| "user#{n}@gmail.com"}
  f.email_confirmation {|fac| fac.email }
  f.password "a12345Den123"
  f.password_confirmation "a12345Den123"
#  f.admin 0
end

Factory.define :admin, :class => User do |f|
  f.sequence(:username) {|n| "admin#{n}"}
  f.sequence(:email) {|n| "admin#{n}@gmail.com"}
  f.email_confirmation {|fac| fac.email }
  f.password "a12345Den123"
  f.password_confirmation "a12345Den123"
  f.admin 1
end

Controller 宏模块:

module ControllerMacros
  def login_admin
    before(:each) do
      @request.env["devise.mapping"] = Devise.mappings[:user]  #it should map to user because admin is not a model of its own.  It produces the same result either way.
      @admin = Factory.create(:admin)
      sign_in @admin
    end
  end

  def login_user
    before(:each) do
      @request.env["devise.mapping"] = Devise.mappings[:user]
      @user = Factory.create(:user)
      sign_in @user
    end
  end
end

路线

devise_for :users
devise_for :admins, :class_name => 'User'

一种解决方案是设置 cache_classes = false，但这并不理想，因为我使用 spork 并且不想在更改模型后重新启动它。

有什么帮助吗？

我的 route 有这样的东西:

  devise_for :accounts, :controllers => {:confirmations => "confirmations"} do
    put "confirm_account", :to => "confirmations#confirm_account"
    get "login" => "devise/sessions#new", :as => :login
    delete "logout" => "devise/sessions#destroy", :as => :logout
    get "register" => "devise/registrations#new", :as => :register
  end

所以在我的 spec/support/controller_macros.rb 我需要改变:

  def login_account
    before(:each) do
      @request.env["devise.mapping"] = Devise.mappings[:account]
      @account = Factory.create(:account)
      sign_in(@account)
    end
  end

到

  def login_account
    before(:each) do
      @request.env["devise.mapping"] = Devise.mappings[:account]
      @account = Factory.create(:account)
      sign_in(:account, @account)
    end
  end

注意 登录(范围，资源)

我希望这有帮助。
