ruby-on-rails - 工厂女孩 : How do define a factory without passing parameters

Question

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

我这样定义我的工厂:

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 factory girl 页面上，他们在示例中定义了工厂，而没有在 之后传递参数。做 (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 之后传递参数。做 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

但我收到错误:

我究竟做错了什么？或者它是一个兼容性问题——即 factory_girl_rails(用于 rails 3)与 factory_girl 的工作方式不同。

谢谢。

这是因为此文档仅适用于 FactoryGirl 测试版。不是稳定版。它是在 README 之上的解释。

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