DRF中有一个serializer的概念,实现的功能是将各种Django Queryset和model instance转换成Python原生格式,这里就省去了你自己写API的时候面临的类型问题,当然也可以逆向操作。官方文档如下:
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 Serializer
class 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.
