我经常使用 Factory Girl 在我的数据库中创建虚假数据。但是每当我创建一个新工厂时，如果发生错误，我最终会得到大量不一致的数据，因为它不支持事务，不会发生回滚 例如(控制台快照)
INSERT INTO `INVOICES` (`created_by`, `creation_date`, `fulfillment_branch_id`, `invoice_date`, `invoice_number`, `invoice_status`, `last_updated`, `last_updated_by`, `order_id`, `order_status`, `parent_order_id`) VALUES ('xx.xx@xx.net', '2015-07-16 11:27:00', '1035280', NULL, NULL, 'Active', '2015-07-16 11:27:00', 'xx.xx@xx.net', 24, 'Invoiced', NULL)
SQL (0.8ms) INSERT INTO `packages` (`created_at`, `created_by`, `shipment_id`, `size`, `status`, `updated_at`, `updated_by`, `value`, `weight`) VALUES ('2015-07-16 11:27:00', 49, NULL, 'LBH', 'active', '2015-07-16 11:27:00', 49, 2448.0, 0.32950726052542545)

谁能解释一下我应该在哪里进行猴子补丁以确保工厂以事务方式运行？
编辑
为了解决我的问题，我想修补 FactoryGirl 模块，以便每次调用时我的 FactoryGirl.create api 都会包含在 ActiveRecord 事务中。
谢谢
最佳答案
这个错误的原因是你对包表的设置
shipment_id: nil
要解决这个问题，您应该为此设置一些信息。示例:
FactoryGirl.define do
factory :example do
shipment
#your another code
发货在哪里 - 是发货模型的关联
关于mysql - 如何将 FactoryGirl 与 ActiveRecord 事务轨结合使用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31446898/
