在 Razorpay 支付网关中，未获取 order_amount。我怎样才能得到金额？

Question

当我使用 Razorpay 支付网关进行支付集成时，未从模型中获取 order_amount。 正如在 models.py 中看到的，有两种方法可以获得订单的总金额，但是尝试其中任何一种，order_amount 都没有发送任何正确的值，因此我被困在这里好几天了。

请帮忙。谢谢你

以下是错误的回溯：

        for order_item in self.items.all():
            total += order_item.get_final_price()
        return total

    def get_amount(self):
        return self.get_total()

Answer 1

您必须将总价格字段更改为像这样的整数字段

total_amount = models.IntegerField(null=True)

或在您的视图中将其更改为整数字段，然后将其乘以 100

total_price = request.POST.get('paying_price')
total_item_price = json.loads(total_price)#for changing float field into integers

然后

amount=total_item_price*100

因为 razorpay 无法将浮点字段理解为值，所以您必须根据需要更改它，这可能会有所帮助
