Beta License: AGPL-3 OCA/product-attribute Translate me on Weblate Try me on Runbot

This module adds a constraint on the internal reference of the product to make it unique across the database.

Table of contents


  • Unable to save a product when a new internal reference or default_code value is the same with an existing record.
  • A pre_init_hook process is initiated when there exist records without an internal reference(default_code). A default value is generated to populate empty field as a temporary value.

Known issues / Roadmap

  • Avoid duplicate warnings. Odoo has a warning for duplicate “Internal Reference” of its own (it doesn’t block from saving). Now both warnings are displayed when trying to save a duplicate “Internal Reference”.
