Mastering XPath Expressions in Odoo QWeb Attributes
A Developer’s Guide
Hey Odoo enthusiasts! 🎉
If you’re working with Odoo, chances are you’ve encountered QWeb templates — the core of Odoo’s front-end customization. To make those templates work seamlessly with dynamic content, XPath expressions become your best friend. Today, I’m excited to dive into the world of XPath expressions in Odoo’s QWeb attributes, guiding you through how they work and why they’re so powerful.
Here’s a collection of essential XPath expressions that will help you customize your templates like a pro. Let’s explore! 🔍
1. Targeting Specific Template Outputs
Expression: expr="//t[@t-out='0']"
This selects all <t> tags where the t-out attribute is set to '0'. This expression is perfect for filtering template outputs and ensuring you're targeting exactly the right parts of your code.
2. Working with JavaScript Files
Expression: expr="//head/script[@id='web.layout.odooscript']"
Need to manipulate JavaScript within a QWeb template? This XPath expression will find a <script> tag inside the <head> that has a specific ID. It's a great way to pinpoint scripts and ensure they’re handled correctly.
