In Odoo 16, the assets management system has changed. The old web.assets_backend no longer exists. Instead, Odoo 16 uses:
- web._assets_backend → For the Community edition
- web._assets_enterprise → For the Enterprise edition
So, if we try to inherit web.assets_backend, Odoo will throw an error because it does not exist.
Solution:
✅ 1. Update the header.xml file
Modify the inherit_id in your XML file:
xml
CopyEdit
<?xml version="1.0" encoding="UTF-8"?> <odoo> <template id="assets_backend_inherit" inherit_id="web._assets_backend" name="Custom Backend Assets"> <xpath expr="." position="inside"> <link rel="stylesheet" type="text/css" href="/custom_theme/static/src/css/theme.css"/> </xpath> </template> </odoo>
If you are using Odoo Enterprise, replace web._assets_backend with web._assets_enterprise.
✅ 2. Correctly Define Assets in __manifest__.py
In Odoo 16, assets are defined inside the assets dictionary. Update your __manifest__.py:
python
CopyEdit
'assets': { 'web._assets_backend': [ '/custom_theme/static/src/css/theme.css', ], },
Again, for Enterprise Edition, use web._assets_enterprise.
Restart odoo
Hi Ahamed,
It seems that you are trying to append the stylesheet.
Do you mind to try the steps below? I took reference from "crm" module.
- Remove the xml, don't append through template inheritance.
- Inside the manifest.py, remove the slash(/) before "custom_theme"
