I have added a custom field to my purchase orders. Based on this field, I would like a specific field on new purchase order lines to automatically be populated. I would like this to work even if the purchase order hasn't been saved yet.

How can I achieve this? I've tried adding a default_get function to purchase order lines, but I have yet to find a way to access the field values of the current order.

@api.model
def default_get(self, fields_list):

I've tried a few different things:

active_po_id = self.env.context.get("active_id")
purchase_order_obj = self.env['purchase.order']
purchase_order_search = purchase_order_obj.search([('id', '=', active_po_id)], limit=1)

and:

order = self.order_id

None of the things I have tried have given me any of the purchase order information. Can anyone help me figure out how to achieve this

Best Answer 


class orderline(models.Model):
    _inherit = 'purchase.order.line'

    @api.onchange('product_id')
    def value(self):
        self.product_qty = self.order_id.test   <order_id is important it connects to Purchase order>
