I'm currently trying to extend the default view that comes with the Barcode application to show additional information on the kanban cards. The extra fields which I want to display are a relation of sale_id which is a field of the stock.picking model but it is a many2one relation from the sale.order model.
This is my current xml file:
<?xml version="1.0" encoding="utf-8"?>
<odoo>
<record id="barcode_inherit" model="ir.ui.view">
<field name="name">stock.barcode.kanban.inherit</field>
<field name="model">stock.picking</field>
<field name="type">kanban</field>
<field name="inherit_id" ref="stock.stock_picking_kanban"/>
<field name="arch" type="xml">
<field name="partner_id" position="after">
<field name="sale_id"/>
</field>
</field>
</record>
</odoo>
This throws a sale_id field cannot be found error.
Adding more information to my question sale_id is a many2one field from the sale.order model
