Activities and mailing trace are linked to documents through a model and a many2one reference field. The latter one is required but is implemented like an integer field, meaning writing 0 is actually a valid value for 'required'. In this commit we add a constraint to ensure we never update activities with a void res_id value. Same for mailing traces. This allows to remove the required attribute on fields to avoid having redundant sql constraints. Source: internal feedback about activities with 0 as res_id Task-2694133 Part-of: odoo/odoo#81292
