创建带有孩子存在状态验证的工厂的父母和孩子 [英] Create Parent and Child with child presence validation Factory Girl

问题描述

有一个包含许多行程的发票的项目.新的故事以我的方式出现，要求发票必须出差.我已经添加了一个验证validates :trips, presence: true，但是由于FactoryGirl试图在创建关联的旅程之前保存发票，所以现在正在炸毁许多测试.

Have a project that has Invoices with many Trips. New story came my way requesting that an Invoice MUST have a trip. I've added a validation validates :trips, presence: true but it is now blowing up a number of my tests since FactoryGirl is trying to save the invoice before creating the associated trip.

FactoryGirl.define do
  factory :invoice do
    sequence(:invoice_id) { SecureRandom.uuid}
    merchant
    amount 100.00
    item_count 1
    paid false
    currency "GBP"
    invoice_type "pre-flight"
    service_rendered false
    cancelled false

    after(:create) { |object| create(:trip, invoice_id: object.invoice_id)}
  end

end

我该怎么做才能创建这些对象.最好是在工厂级别，因为有许多测试都在使用这种行为(并且由于这种行为而当前失败).

What can I do to create these objects. Preferably at the factory level since there are numerous tests utilizing this behavior (and currently failing because of it.) This seems like a good solution at the test level.

更新 现在仍在努力使我的测试变得绿色. 42测试使用以下代码出错.

Update Still struggling with getting my tests green now. 42 Tests are erroring out with the following code.

验证失败:行程不能为空

Validation failed: Trips can't be blank

我在FactoryGirl代码中当前更新的行

My current updated line in my FactoryGirl code

  before(:create) { |object| object << build(:trip, invoice_id: object.invoice_id)}

这也是我的旅行工厂.

FactoryGirl.define do
  factory :trip do
    depart_airport "MCI"
    arrive_airport "ORD"
    passenger_first_name "Joe"
    passenger_last_name "Business"
    passenger_count 1
    departure_date {10.days.from_now}
    invoice
  end

end

立即工作 @andrykonchin是正确的.我错过了before(:create)...

Working Now @andrykonchin was right. I had missed something in my before(:create)...

before(:create) { |object| object.trips << build(:trip, invoice_id: object.invoice_id)}

before(:create) { |object| object.trips << build(:trip, invoice_id: object.invoice_id)}

推荐答案

before回调可能会为您提供帮助.

before callback may help you.

从文档:

before(:create)-在保存工厂之前调用(通过 FactoryGirl.create)

before(:create) - called before a factory is saved (via FactoryGirl.create)

它看起来像这样:

before(:create) { |object| object.details << build(:invoice_detail)}
