Delivered / Invoiced / Paid statuses on purchase orders

Context

The team had to open each purchase order and navigate between receipts, invoices and payments to know the real status. No consolidated information visible at a glance — it was slowing down customer responses.

What was built

• 3 computed stored fields: x_delivery_status, x_invoice_status_cobra, x_payment_status (None / Partial / Complete)
• Horizontal colored badges on the PO form + optional badge columns in list views (enabled by default)
• Filters and groupby in the PO search
• Auto-lock PO when all 3 statuses = Complete (a write() vs _write() bug to fix)
• Internal email drafted to inform the team

What was tricky

• View validation at upgrade doesn't see additions from sibling views — purchase_stock in depends + priority=20 required
• The purchase_order_tree view contains 3 variants of <list>: only //list[@decoration-muted] works without conflict

Stack

Python, Odoo 18 XML, cobra_vendor_payment_confirm module, purchase + purchase_stock, Bootstrap, Git (preprod3 → hl/vendor-payment-confirm → main).

What this illustrates

Feature built iteratively — each push to preprod3 reveals unexpected framework behavior, Claude diagnoses, proposes a surgical fix, relaunches. The production deployment includes merge conflict resolution and cleanup of a test artifact.
