"Boost Odoo Performance with @lazy_property: A Smart Cache"

🚀 Boost Your Odoo Performance with @lazy_property When working with Odoo, every millisecond counts — especially on heavy models like res.partner or sale.order. That’s where the @lazy_property decorator comes in. 🔹 What is @lazy_property? @lazy_property is a decorator in Odoo (odoo.tools) that allows you to compute a value once per record and reuse it without recalculating during the same request. Think of it as a smart cache for model properties. 🔹 Why should we use it? - Prevents repeated database queries within a single request. - Optimizes performance for expensive calculations. - Keeps the code cleaner (no manual caching logic needed). - Directly improves runtime efficiency 🔹 Where can we use it? Use @lazy_property when: - The value doesn’t change during the request lifecycle. - It requires heavy DB operations or complex calculations. - Example: counting related records, aggregated values, pre-processed settings. 🔹 How can we use it? Please look at the attached image for code snippet: ✅ The first time you access partner.sale_order_count, it runs the query. ✅ Next calls in the same request will use the cached result — no extra queries! 🔹 How does it reduce runtime & improve Odoo experience? - Without @lazy_property: each call executes a new DB query. - With @lazy_property: only one query per record per request. - Result: faster views, optimized API responses, and smoother user experience. 💡 Pro Tip: Don’t overuse it. If the value can change within the same request, avoid caching with @lazy_property. ❓ Open Question Have you already used @lazy_property in your Odoo projects? 👉 If yes, what’s your favorite use case?
