If I add "partner_shipping_id" to my Sale.Order TreeView, it will automatically show the name of the Delivery Address. I want to show the "city" or "place" of a Delivery Address rather than the name. How can I specify I want to show another field than the name of this Address?
I don't mind having to add a field e.g. "x_city" to the sale.order table, but how can I set this field to automatically store "partner_shipping_id.city" values? That way I can add x_city to my TreeView, and show it in my List View.
Is there a better way to do this? How?
