restframework 视图

一、逻辑封装

    path('author/', views.AuthorView.as_view()),
    path('author/<pk>/', views.AuthorDetailView.as_view()),

路由

from rest_framework import mixins, generics
"""
本质：封装逻辑
1.return 父类的方法
2.queryset serializer_class 两个参数必要（看源码）
3.mixins.ListModelMixin和mixins.CreateModelMixin 没有的方法到generics.GenericAPIView去找
4.url的参数要改成pk，根据get_obj() 源码

    queryset = Author.objects.all()
    # print(queryset)
    serializer_class = AuthorModelSerializer
