Bulk-Update Relational Fields in Odoo Mass Update

Extra Tools June 7, 2026 · 5 min read

Mass Update is one of the most practical productivity tools in Odoo — select hundreds of records, change a field once, and apply it everywhere. But until now, relational fields like Many2one and Many2many were often left out, forcing teams into slow manual edits or custom scripts.

What Changes With Dynamic Relations

Mass Update Dynamic Relations extends the Mass Update wizard with full support for linked fields. Dynamic OWL widgets read each field's relation and open the correct model picker — partners, products, tags, users, or any comodel configured on your model.

Many2one in Practice

Need to reassign a salesperson on 200 open quotations? Pick the Many2one field, choose the new user, and click Update. The picker automatically resolves the related model for that field — no hard-coded configuration per model.

Many2many: Add, Remove, Clear

Works With Your Existing Setup

Install alongside Mass Update — All in One Record Updater. Any model already enabled in Mass Update configuration gains relational field support automatically. Updates are logged in Mass Update history as usual.
