P60表结构的设计

class Order(models.Model):
    """订单"""
    oid = models.CharField(verbose_name="订单号", max_length=64)
    title = models.CharField(verbose_name="名称", max_length=64)
    price = models.IntegerField(verbose_name="价格")
    status_choices = (
        (1, "待支付"),
        (2, "已支付"),
    )
    status = models.SmallIntegerField(verbose_name="状态", choices=status_choices)
    admin = models.ForeignKey(verbose_name="管理员", to="Admin", on_delete=models.CASCADE)

        form.save()
        return JsonResponse({"status": True})
    # else:
