【问题描述】：
我经常使用 Factory Girl 在我的数据库中创建假数据。但是每当我创建一个新工厂时，如果发生错误，我最终会得到很多不一致的数据，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)
ActiveRecord::StatementInvalid: Mysql2::Error: Column 'shipment_id' cannot be null: 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)

谁能解释我应该在哪里打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，以便我的 FactoryGirl.create api 在每次调用时都包含在 ActiveRecord 事务中。
谢谢
【问题讨论】：
-
您的意思是在运行时它会在数据库中创建记录，如果失败则将记录保留在数据库中？如果是这种情况，请使用数据库清理器来避免这种情况
-
您是否有理由不能将数据创建包装在事务中？通常，FactoryGirl 将在测试环境中使用，如果它失败并不重要，因为无论如何都会清理数据库。或者，如果您在种子中使用它，您可以将调用包装在事务中。如果您通过控制台创建数据，那么在种子文件中执行它可能更可重复。

我有时会在开发中使用 FactoryGirl 来创建假数据，但在此过程中大部分时间我以大量不一致的数据结束
