Question

我有一个具有以下关联的模型：-

 class Order < ApplicationRecord
  belongs_to :customer, inverse_of: :orders
  belongs_to :user, inverse_of: :orders
  belongs_to :shipping_address, class_name: "Customer::Address", inverse_of: :shipped_orders
  belongs_to :billing_address, class_name: "Customer::Address", inverse_of: :billed_orders
end

此外，customer_address还有一个字段customer_id。我的工厂是这样的：-

FactoryGirl.define do
  factory :order do 
    customer
    user
    association :shipping_address, factory: :customer_address, customer_id: customer.id 
    association :billing_address, factory: :customer_address, customer_id: customer.id
  end
end

但是我无法访问customer.id。我收到此错误：-

undefined method `id' for #<FactoryGirl::Declaration::Implicit:0x007fa3e6979d70>

如何将customer.id传递给shipping_address和billing_address关联？

Answer 1

您可以使用after(:build)回调来建立您的customer_address记录。

FactoryGirl.define do
    factory :order do 
        association :customer
        association :user
        after(:build) do |order|
            order.shipping_address = FactoryGirl.build(:customer_address, customer_id: order.customer_id)
            order.billing_address = FactoryGirl.build(:customer_address, customer_id: order.customer_id)
        end
    end
end

Rails工厂具有与同一对象的多个关联
