我有一个One2many字段：“ prod_id”，“ prod_qty”。我想添加产品明智的数量。 '另一个One2many中每种产品的总数量

Question

• 我有一个One2many字段：'prod_id'，'prod_qty'。

• 我想增加产品数量。

• 另一个One2many中每种产品的总数量

prod = []
        for rec in self.sale_wiz_ids:
            r = list(filter(lambda product: product['prod_id.id'] == rec.prod_id.id, prod))
            self.total_qty1 += rec.prod_qty

    partner_id = fields.Many2one('res.partner', string='Customer')

    total_qty = fields.Integer("Total Quantity")

    total_qty1 = fields.Integer("Total Quantity")
