XML IDsΒΆ

The OpenUpgrade analysis files give a representation of the XML IDs that a module defines, in comparison with the previous release of the module.

XML IDs which do not occur in the updated version of all installed modules will be removed automatically by the Odoo server, if they do not have the noupdate attribute. Therefore, you can ignore most entries here, such as

  • ir.actions.*

  • ir.model.fields

  • ir.model.access

  • ir.model

  • ir.ui.*

  • res.country*

  • res.currency*

When XML ids of such record types change, the record will be recreated under the new id, and the old record will be unlinked.

More interesting are data that are defined with the noupdate flag. In general, you need to cover two cases in your scripts.

  • Renamed XML ids of noupdate records. If a product category, or a res.groups entry has been renamed, you should pass them to rename_xmlids() so that the item in your current database survives the migration in its original form. If the XML id of a renamed noupdate record is not renamed this way, the new record will be created in addition to the existing one, and the existing record will lose its xml id.

  • Modified fields of noupdate records, as collected in the noupdate_changes.xml in the migration analysis directory. When developing the migration scripts for a particular module, review this file and comment out any fields that must not be overwritten. If there is any data left that you want to take, load it from your post migration script using load_data().
