Question

我已经使用reference 1作为我的电话号码模型字段和序列化程序。它工作正常，一切都很好。现在，我试图在这两个包 djsoer 和 djangorestframework-jwt 的Django Rest Framework中实现Json Web令牌。我正在管理旧的（django 1.11）代码库并将其迁移到Django2。现在，每当我尝试创建新的身份验证令牌时，都会收到内部服务器错误。错误消息：

TypeError: Object of type 'PhoneNumber' is not JSON serializable

我知道Django-phonenumber-field包中的PhoneNumber对象对此负责。但是，错误堆栈位于 djangorestframework-jwt 中。如何在JWT上添加/传递PhoneNumber序列化程序？

[我不知道需要哪个代码库，因此我没有添加任何代码库。问我，我稍后再描述/添加。]

TIA。

这与JWT不相关。 Rest Framework试图将“电话号码”字段序列化为json，但是它不知道该怎么做。查看有关如何实现a custom field的DRF文档-该字段负责了解如何在初始数据类型和序列化表示之间进行转换，反之亦然。
