❓ Frequently Asked Questions

Can I modify models after activation?

Yes! Use the Update Model button. The system will add new fields, update existing ones, and safely remove unused fields without losing data.

What happens to my data if I deactivate?

Deactivation removes the models but keeps the Builder Module configuration. You can reactivate later. However, all data in the models will be lost.

Can I create computed fields?

Not yet. This version focuses on basic fields. Computed fields require Python code.

Can I customize the views?

Generated views are automatic. For custom layouts, you'll need to edit the XML views in developer mode or create a custom module.

How do I backup my work?

Use the Export to JSON feature to save module definitions. Also backup your Odoo database regularly.

Can I share modules with other Odoo instances?

Yes! Export to JSON and import on the target instance. Ensure dependencies (related models) exist.
