Python IntegrityError在表上插入或更新；订单“U订单”；违反外键约束“；

我正在尝试在Django 1.7中构建一个电子商务站点，除了尝试使用签出外，其他一切都正常，我遇到了以下错误。我不确定它是怎么做到的，因为它在我的本地主机上运行得很好，但在我尝试部署到webfaction上时就不行了。 非常感谢

Exception Type: IntegrityError at /checkout/
Exception Value: insert or update on table "orders_order" violates foreign key constraint "billing_address_id_41625ebca5013523_fk_accounts_useraddress_id"

重要的细节如下：

DETAIL:  Key (billing_address_id)=(1) is not present in table "accounts_useraddress".

问题是您试图将订单与数据库中尚未存在的帐单地址链接

---

在您的代码中，您需要确保账单地址已保存到数据库中，然后才能尝试通过外键保存与其相关的对象。

您对如何执行此操作有何建议？我在尝试我觉得自己很愚蠢：-（你能从你正在执行new_order.save（）的views.py文件中发布一段代码吗？
