FactoryGirl：如何在不传递参数的情况下定义工厂

Question

我正在使用 Rails 3/factory_girl_rails/Rspec 2 和 Ruby 1.8

我已经这样定义了我的工厂：

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

并且我的测试运行良好。

我注意到在工厂女孩页面上，他们在示例中定义工厂，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，我尝试模拟定义工厂，而不在 do 之后传递参数，并将代码更改为：

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

但我收到错误：

我做错了什么？或者这是一个兼容性问题——即，也许factory_girl_rails（适用于rails 3）与factory_girl的工作方式不同。

谢谢。

这是因为本文档仅适用于 FactoryGirl beta。不是稳定版本。它在 README 之上进行了解释。

稳定的文档在这里： http://github.com/thoughtbot/factory_girl/tree/1.3 .x
