결제 중간 이탈

order_detail까지 모두 잘 따라 만들었습니다.

이전에 테스트했을 때는 분명 안그랬던거 같은데...

결제를 하다가 중간에 나오거나 되돌아가면, 이게 redirect되면서 order_detail의 페이지로 이동합니다.

제 생각에는 결제를 시도하기 위한 페이지로 다시 돌아가는게 맞다고 생각하는데...

원래 이게 맞는건지, 아니면 제 코드가 잘못된건지 여쭤볼 수 있을까요?

models.py

class OrderPayment(AbstractPortonePayment):
    order = models.ForeignKey(Order, on_delete=models.CASCADE, db_constraint=False, help_text="주문")

    def update(self):
        super().update()
        if self.is_paid_ok:
            self.order.status = Order.Status.PAID
            self.order.save()
            # 다수의 결제시도
            self.order.orderpayment_set.exclude(pk=self.pk).delete()
        elif self.pay_status in (self.PayStatus.CANCELED, self.PayStatus.FAILED):
            self.order.status = Order.Status.FAILED_PAYMENT
            self.order.save()

    @classmethod
    def create_by_order(cls, order: Order) -> "OrderPayment":
        return cls.objects.create(
            order=order,
            name=order.name,
            desired_valuation=order.valuation,
            buyer_name=order.user.name,
            buyer_email=order.user.email,
        )
