django drf GenericAPIView和ListAPIView

Posted 2021-02-14 chester.chen

drf提供了更快捷的查询方法ListModelMixin+GenericAPIView，和ListAPIView

1.ListModelMixin+GenericAPIView

from django.shortcuts import render

from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework import status
from rest_framework.parsers import JSONParser
from rest_framework import mixins, generics
from rest_framework.generics import ListAPIView
from rest_framework.pagination import PageNumberPagination
from goods.models import Goods
from goods.serializer import GoodsSerializer


class GoodsList(mixins.ListModelMixin,generics.GenericAPIView):
    queryset = Goods.objects.all()[:10]
    serializer_class = GoodsSerializer

    def get(self,request,*args,**kwargs):
        return self.list(request,*args,**kwargs)


# 需要配置setting.py中的REST_FRAMEWORK节点
class GoodsList(ListAPIView):
    queryset = Goods.objects.all()[:10]
    serializer_class = GoodsSerializer

2.ListAPIView

from django.shortcuts import render

from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework import status
from rest_framework.parsers import JSONParser
from rest_framework import mixins, generics
from rest_framework.generics import ListAPIView
from rest_framework.pagination import PageNumberPagination
from goods.models import Goods
from goods.serializer import GoodsSerializer


class GoodsList(ListAPIView):
    class GoodsPagination(PageNumberPagination):
        page_size = 1
        page_size_query_param = \'pageSize\'
        page_query_param = \'p\'
        max_page_size = 100

    queryset = Goods.objects.all()[:10]
    serializer_class = GoodsSerializer
    pagination_class = GoodsPagination

 

我们可以从源码中看到ListAPIVIew继承了ListModelMixin+GenericAPIView
