如何在报价单的小计中添加另一个折扣?

问题描述

报价单行中有一个 subtotal (price_subtotal) 字段。

添加一个新字段 extra_discount

我已经尝试过此代码,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 没有任何作用。

那么,我该如何实现?

解决方法

我会尝试覆盖 sale.order.line.price_subtotal 字段后面的 the computation method

但我不确定 api.depends() 扩展(再添加一个重新计算触发器字段)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])
