FactoryGirl 在第一次调用时构建未初始化的对象，然后按预期工作

Question

使用：

• factory_girl_rails v4.3.0
• rails v4.0.1
• rspec-rails v2.14.0

我对@9​​87654324@ 的第一次调用返回了一个所有nil 属性的对象。如果我再次调用它，它会按照工厂定义按预期构建对象。这是一个演示异常行为的撬动会话：

∴ rspec ./spec/controllers/admin/base_controller_spec.rb:10
Run options: include {:locations=>{"./spec/controllers/admin/base_controller_spec.rb"=>[10]}}

Frame number: 0/25

     2:   def sign_in(user_type = nil)
 =>  3: binding.pry
     4:     user = FactoryGirl.create(user_type) unless user_type.nil?
     5:
     6:     if user.nil?
     7:       request.env['warden'].stub(:authenticate!).

     9:       controller.stub :current_user => nil
    10:     else
    11:       request.env['warden'].stub :authenticate! => user
    12:       controller.stub :current_user => user
    13:     end
    14:   end

               :last_name => "Blogs",
              :roles_mask => 1
}

还有工厂：

FactoryGirl.define do
  factory :user do
    email 'joe@email.com'
    username 'joe_blogs'
    password 'my_password'
    first_name 'Joe'
    last_name 'Blogs'

    factory :admin_user do
      first_name 'Jan'
      email 'jan@email.com'
      username 'jan_blogs'
      password 'my_password'

      roles [:admin]
    end
  end
end

任何想法我做错了什么或发生了什么？谢谢。

FactoryGirl.build 将初始化用户对象，但不保存它，而FactoryGirl.create 将初始化并将对象保存到（测试）数据库。

您的应用是否需要为每个用户提供唯一的电子邮件地址？ factory_girl documentation 展示了如何创建一个独特的序列，您可以将其用于用户模型实例的电子邮件字段。
