public function MigrateOrder::onPreRowDelete in Commerce Migrate 3.0.x

Same name and namespace in other branches

8.2 src/EventSubscriber/MigrateOrder.php \Drupal\commerce_migrate\EventSubscriber\MigrateOrder::onPreRowDelete()
3.1.x src/EventSubscriber/MigrateOrder.php \Drupal\commerce_migrate\EventSubscriber\MigrateOrder::onPreRowDelete()

Reacts to the PRE_ROW_DELETE event.

For commerce_order rollbacks we want to preserve the order items and prevent the 'usual' commerce behavior of deleting all order items belonging to an order when deleting that order. That is done by removing all order items from the order and saving the order.

The extra steps to remove the order items from the order may significantly increase the time to perform a rollback. To mitigate this it is best to use drush and limit the number of records migrated during development. This can be done with the 'limit' option or the 'idlist' option, as shown in the following examples.


drush migrate-import --limit=5 some_migration
drush migrate-import --idlist=42 some_migration

It is also possible to disable this feature and use a custom event subscriber. Instructions on how to do that is in the Symfony documentation.
