how can i add quantity on hand from image 1 (product) to image 2 (Order lines), and the suppliers too

i tried this code

qty_on_hand = fields.Char(related="product_id.qty_available")

but i got this error

odoo type of related field sale.order.line.qty_on_hand is inconsistent with product.product.qty_available

Answer 1

what is suppliers explain that please. i mean what will that field contain.. and for the quantity available you are doing it a bit wrong. see the code below... you have to do like this...

inherit sale.order.line and add a field

qty_on_hand = fields.Float('On Hand Qty', related='product_id.qty_available')

add this qty_available field in xml by inheriting the the order_lines view thats all for on hand quantity .
