How to use FactoryGirl with ActiveRecord transaction rails

Question

I Use Factory Girl a lot to create fake data in my database. But whenever I create a new factory and if a error occurs I end up with lot of inconsistent data since it does not support transaction no rollback occurs For example (snapshot of console)

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)

    from scripFactoryGirl.reload

Can anyone explain where I should monkey patch to ensure factory runs transactionally?

Edit

To clear my question I want to patch FactoryGirl module so that my FactoryGirl.create api gets wrapped in ActiveRecord transaction everytime I call it.

Thank you

Answer 1

The reason of this error it's that you set for package table

shipment_id: nil 

To solve this you should set some info for this. Example:

FactoryGirl.define do
  factory :example do
    shipment

    #your another code

where is shipment - is association for Shipment-model
