报价单行中有一个subtotal(price_subtotal) 字段。

我添加了一个新字段extra_discount。

我已经尝试过这段代码，但无济于事。

@api.depends('product_uom_qty', 'price_unit', 'extra_discount')
    def compute_all(self):
        for record in self:
            record.price_subtotal = (record.product_uom_qty * record.price_unit) - record.extra_discount

它对subtotal.

那么，我该如何实现呢？

我会尝试覆盖字段后面的计算方法sale.order.line.price_subtotal。

但我不确定api.depends()扩展（再添加一个重新计算触发字段）是否按预期工作。

但它应该看起来像这样：

class SaleOrderLine(models.Model):
    _inherit = "sale.order.line"

    extra_discount = fields.Float()

    @api.depends('product_uom_qty', 'discount', 'price_unit',
                 'tax_id', 'extra_discount')
    def _compute_amount(self):
        """
        Compute the amounts of the SO line.

        Fully overridden to add field extra_discount to the
        formula and triggers.
        """
        for line in self:
            price = line.price_unit * (1 - (line.discount or 0.0) / 100.0)
            # new: substract extra_discount
            price -= line.extra_discount
            taxes = line.tax_id.compute_all(price, line.order_id.currency_id, line.product_uom_qty, product=line.product_id, partner=line.order_id.partner_shipping_id)
            line.update({
                'price_tax': sum(t.get('amount', 0.0) for t in taxes.get('taxes', [])),
                'price_total': taxes['total_included'],
                'price_subtotal': taxes['total_excluded'],
            })
            if self.env.context.get('import_file', False) and not self.env.user.user_has_groups('account.group_account_manager'):
                line.tax_id.invalidate_cache(['invoice_repartition_line_ids'], [line.tax_id.id])
