DRF中有一個serializer的概念，實現的功能是將各種Django Queryset和model instance轉換成Python原生格式，這裡就省去了你自己寫API的時候面臨的類型問題，當然也可以逆向操作。官方文檔如下：
Serializers allow complex data such as querysets and model instances to be converted to native Python datatypes that can then be easily rendered into JSON, XML or other content types. Serializers also provide deserialization, allowing parsed data to be converted back into complex types, after first validating the incoming data.
The serializers in REST framework work very similarly to Django's Form and ModelForm classes. We provide a Serializerclass which gives you a powerful, generic way to control the output of your responses, as well as a ModelSerializer class which provides a useful shortcut for creating serializers that deal with model instances and querysets.
