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:
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
