ruby-on-rails – FactoryGirl：如何在不传递参数的情况下定义工

我用这种方式定义了我的工厂：

Factory.define :user do |u|
  u.name       'Some guy'
  u.sequence(:email) {|n| "person#{n}@example.com" }
  u.password   'password'
end

Factory.define :password_reset_user,:parent => :user do |user|
  user.password_reset_key   '111222333444'
end

我的测试运行良好.

我注意到在工厂女孩页面上他们在他们的例子中定义了工厂而没有在do之后传递参数(http://github.com/thoughtbot/factory_girl)：

# This will guess the User class
FactoryGirl.define :user do
  factory :user do
    first_name 'John'
    last_name  'Doe'
    admin false
  end

  # This will use the User class (Admin would have been guessed)
  factory :admin,:class => User do
    first_name 'Admin'
    last_name  'User'
    admin true
  end

  # The same,but using a string instead of class constant
  factory :admin,:class => 'user' do
    first_name 'Admin'
    last_name  'User'
    admin true
  end
end

为了清理我的代码,我试图模仿定义工厂而不在do之后传递参数并将我的代码更改为：

Factory.define :user do
  factory :user do
    name       'Some guy'
    sequence(:email) {|n| "person#{n}@example.com" }
    password   'password'
  end

  factory :password_reset_user,:parent => :post do
    password_reset_key   '111222333444'    
  end
end

但我得到错误：

我究竟做错了什么？或者它是兼容性问题 – 也许factory_girl_rails(用于rails 3)与factory_girl的工作方式不同.

谢谢.
