使用FactoryGirl，如何将accepts_nested_attributes_for 子属性插入到我正在创建的对象中？

Question

factory :payment_object do
  company_id 1
  user_id 1
  delivery_date (Date.today + 1)
  payment_terms 'CBD'
  vendor 'Apple'
  currency 'USD'

  # item
    # name "Macbook"
    # quantity 1
    # price 1000
  # item
    # name "Magic Mouse"
    # quantity 1
    # price 65   
end

Answer 1

这是一种可以在您的规格内完成此操作的方法。

before(:each) do
  @payment_object = FactoryGirl.build(:payment_object)
  5.times do 
    @payment_object.items << FactoryGirl.build(:item)
  end
  @payment_object.save!
end

Answer 2

这是不直观的，但 Factory_girl 文档说明了当您搜索“has_many”时如何：

，首先，创建另一个工厂：

FactoryGirl.define do
  factory :item do
    name "Macbook"
    quantity 1
    price 1000
    payment_object
  end
end

然后在代码中使用它，如下所示：

FactoryGirl.define do
  factory :payment_object do
    company_id 1
    user_id 1
    delivery_date (Date.today + 1)
    payment_terms 'CBD'
    vendor 'Apple'
    currency 'USD'

    # This is how you reference the list with your items
    ignore do
      items_count 5  # the number items that should be in the list
    end
    after(:create) do |payment_object, evaluator|
        FactoryGirl.create_list(:item, evaluator.items_count, payment_object: payment_object)
    end


  end
