Extend Calendar Popover View in Odoo 16

Question

I’m trying to extend a calendar view in Odoo 16, specifically the “popover”. I’ve followed various steps and guides, but I keep encountering the following error:

odoo.tools.convert.ParseError: while parsing None:3, somewhere inside.

I can’t figure out what I’m doing wrong. Can anyone help me?

Thank you very much!

The file should be added to the assets entry under web.assets_backend like they did in the calendar module

Example:

{
    'name': 'My Module',
    'version': '1.0',
    'summary': 'Estende la vista del calendario per aggiungere più campi',
    'category': 'Calendar',
    'depends': ['calendar'],
    'assets': {
        'web.assets_backend': [
            'my_module/static/src/views/attendee_calendar_common_popover_extension.xml',
        ],
    },
    'installable': True,
    'application': False,
}

You need to change your code to use QWEB Template inheritance

Example:

<?xml version="1.0" encoding="UTF-8"?>
<templates>
    <t t-name="cf_toCalendar.attendee_calendar_common_popover_extension_body" t-inherit="calendar.AttendeeCalendarCommonPopover.body" t-inherit-mode="extension" owl="1"> 
        <xpath expr="//ul[hasclass('o_cw_popover_fields_secondary')]" position="inside">
                       
      </xpath>
    </t>
</templates>
