基于视图子类实现接口

11.1 视图子类介绍

(1） CreateAPIView

提供 post 方法

继承自： GenericAPIView、CreateModelMixin

(2）ListAPIView

提供 get 方法

继承自：GenericAPIView、ListModelMixin

(3）RetireveAPIView

提供 get 方法

继承自: GenericAPIView、RetrieveModelMixin

(4）DestoryAPIView

提供 delete 方法

继承自：GenericAPIView、DestoryModelMixin

(5）UpdateAPIView

提供 put 和 patch 方法

继承自：GenericAPIView、UpdateModelMixin

(6）RetrieveUpdateAPIView

提供 get、put、patch方法

继承自： GenericAPIView、RetrieveModelMixin、UpdateModelMixin

(7）RetrieveUpdateDestoryAPIView

提供 get、put、patch、delete方法

继承自：GenericAPIView、RetrieveModelMixin、UpdateModelMixin、DestoryModelMixin

(8）RetrieveDestoryAPIView

提供 get、delete方法

继承自：GenericAPIView、RetrieveModelMixin、DestoryModelMixin

(9）ListCreateAPIView

提供 get、post方法

继承自：GenericAPIView、ListModelMixin、CreateModelMixin

11.2 快速实现接口

视图

"""
视图子类是通用视图类和模型扩展类的子类
    ListAPIView = GenericAPIView + ListModelMixin           获取多条数据
    CreateAPIView = GenericAPIView + CreateModelMixin       添加一条数据
    RetrieveAPIView = GenericAPIView + RetrieveModelMixin   获取一条数据
    UpdateAPIView = GenericAPIView + UpdateModelMixin       更新一条数据
    DestroyAPIView = GenericAPIView + DestroyModelMixin     删除一条数据
组合视图子类：
    ListCreateAPIView = ListAPIView + CreateAPIView
    RetrieveUpdateAPIView = RetrieveAPIView + UpdateAPIView
    RetrieveDestroyAPIView = RetrieveAPIView + DestroyAPIView
    RetrieveUpdateDestroyAPIView = RetrieveAPIView + UpdateAPIView + DestroyAPIView
