我有 2 个模型，一个接受另一个模型的属性，我试图找到一种聪明的方法来使用 Factory girl 来设置两者的数据。

Class Booking
has_many :booking_items
accepts_nested_attributes_for :booking_items

Class BookingItem
belong_to :booking

我的工厂

Factory.define :booking do |f|
  f.bookdate Date.today+15.days
  f.association :space
  f.nights 2
  f.currency "EUR"
  f.booking_item_attributes Factory.build(:booking_item) # doesn't work
end

Factory.define :booking_item do |f|
  f.association :room
  f.bookdate Date.today
  f.people 2
  f.total_price 20
  f.association :booking
end

预订规格

require "spec_helper"

describe Booking do

  before(:each) do
    @booking = Factory.create(:booking)
  end

  it "should be valid" do
    #needs children to be valid
    @booking.should be_valid
  end


end

我环顾了 rdocs，但似乎找不到我要找的东西。

如果我理解正确，你想这样做，但语法更简洁：

booking_item = Factory(:booking_item, :people => 4)
booking = Factory(:booking, :booking_item => booking_item)

当然，您可以像这样快捷方式：

def with_assocs factory, assocs_hashes = {}, attrs = {}
  assoc_models = Hash[ assocs_hash.map { |k, v| [k, Factory(k, v)] } ]
  Factory factory, attrs.merge(assoc_models)
end

并像这样使用：

@booking = with_assocs :booking, :booking_item => {:people => 3}
@booking.should be_valid

在具有类似工厂定义的active_factory 插件中，它看起来像这样：

models { booking - booking_item(:people => 3) }
booking.should be_valid

不幸的是，我还没有实现与 factory_girl 的集成。虽然如果您有兴趣，任何输入都是非常欢迎的。
