hi every one 

in odoo 18 I want to edit the stock.picking form and if I select partner

the products in the Operations tab must be shown like this the user try to pick a product he see only the products that have the same partner in his vendor list

and I try this code 

class StockPickingCo(models.Model):
    _inherit = 'stock.picking'

    @api.onchange('partner_id')
    def _onchange_partner_id_filter_products(self):
        print("_onchange_partner_id_filter_products")
        if self.partner_id:
            return {
                'domain': {
                    'move_ids_without_package.product_id': [
                        ('seller_ids.partner_id', '=', self.partner_id.id)
                    ]
                }
            }
        return {
            'domain': {
                'move_ids_without_package.product_id': []
            }
        }

and this 

 

class StockMove(models.Model):
    _inherit = 'stock.move'

    @api.onchange('product_id')
    def _onchange_product_id_domain(self):
        print("_onchange_product_id_domain")
        if self.picking_id and self.picking_id.partner_id:
            print("_onchange_product_id_domain - 0", self.picking_id)
            return {
                'domain': {
                    'product_id': [
                        ('seller_ids.partner_id', '=', self.picking_id.partner_id.id)
                    ]
                }
            }
        return {}
