Ever struggled with computed fields in Odoo? Especially when building a WMS Warehouse System?
Let’s break it down with some dev-friendly questions!
🤔 What exactly are computed fields in Odoo, and why should you care when building a WMS Warehouse System?
They're fields calculated from other fields—super useful for totals, weights, statuses, and more!
🔍 How does Odoo know when to recalculate a computed field?
That’s where @api.depends comes in. Example:
python
@api.depends('qty_done', 'product_id')
def computetotal_weight(self):
...
❓What happens if you skip @api.depends?
💥 Your computed field won’t auto-update. This breaks things, especially in warehouse flows like real-time stock or pickings.
📊 Want to search or filter by a computed field in list views?
Add store=True.In a WMS Warehouse System, that’s critical for reporting & KPIs.
🛑 Can too many dependencies slow things down?
Yes! Avoid listing unnecessary fields in @api.depends. More fields = more recomputes = slower performance in big warehouses.
🤯 Should you use @api.onchange instead?
Only for UI form updates—not for stored values. Don’t confuse the two!
✅ Final check: Is your function pure (no side effects)? Good. That’s best practice for stable, reliable WMS logic in Odoo.
