But the pattern is important for preventing future issues. + +**Q: Can I use this pattern in other templates?** +A: Yes! This is now the standard pattern for all Odoo templates in this project. + +**Q: What if I need more complex logic?** +A: You can chain multiple `t-set` statements, each computing one safe variable. + +**Q: Does this impact performance?** +A: No - `t-set` is evaluated once during template compilation, not on each render. + +--- + +## Related Resources + +- [Odoo QWeb Documentation](https://www.odoo.com/documentation/18.0/developer/reference/frontend/qweb.html) +- [Odoo Template Reference](https://www.odoo.com/documentation/18.0/developer/reference/backend/orm.html#templates) +- [Python Ternary Expressions](https://docs.python.org/3/tutorial/controlflow.html#more-on-conditions) + +--- + +## Navigation + +``` +docs/ +├── TEMPLATE_FIX_INDEX.md (YOU ARE HERE) +├── FIX_TEMPLATE_ERROR_SUMMARY.md (Complete analysis) +├── QWEB_BEST_PRACTICES.md (Development guide) +├── README.md (Project documentation index) +└── ...
