Minin混合类高度封装

from sers.models import  Book
from rest_framework import serializers
from rest_framework.mixins import ListModelMixin,CreateModelMixin,UpdateModelMixin,DestroyModelMixin,RetrieveModelMixin

# ListCreateAPIView方法集成了GenericAPIView,ListModelMixin,CreateModelMixin 三个类，且写了list 和 create的方法
from rest_framework.generics import  ListCreateAPIView
# RetrieveDestroyAPIView方法集成了GenericAPIView,UpdateModelMixin,RetrieveModelMixin,DestroyModelMixin 四个类
# 且写了retrieve、update、destroy 的方法
from rest_framework.generics import RetrieveDestroyAPIView

# rest_framework.generics 库里面还有其他灵活的方法 如下:
# RetrieveAPIView 只有查的方法--get
# RetrieveDestroyAPIView 查看加删除的方法 get和delete
# RetrieveUpdateDestroyAPIView 查看加更新的方法  get和updata


class BookSerializers(serializers.ModelSerializer):
    class Meta:
        model=Book
