Before this revision, any m2o with an ir.* model as inverse could have the ondelete policy as 'restrict', either by default if it was required or by setting it explicitly in the field declaration. This is problematic because ir.* models are reflection models and they *MUST* be deleted during an uninstall of the module that introduces them, otherwise tables, fields, constraints, etc. are left in the database, this is why 'restrict' doesn't make sense UNLESS the unlink is being performed by an user and not by the system (uninstall). As a solution, this revision sets the default to cascade if the field is required, otherwise null. If the programmer explicitly sets a required m2o field with an ir.* model as an inverse to ondelete='restrict', it is considered an unsupported use-case and the registry will crash during loading with a clear error explaining that it is not supported. closes odoo/odoo#39739 Signed-off-by: Adrian Torres (adt) <adt@odoo.com>
