不使用使用混合（mixins）

自己重構get，put等函數，全部手寫，代碼重復率很高：

from rest_framework.views import APIView
from rest_framework.response import Response
from .models import *
from django.shortcuts import HttpResponse
from django.core import serializers
from rest_framework import serializersclass BookSerializers(serializers.ModelSerializer):class Meta:model=Bookfields="__all__"#depth=1class PublshSerializers(serializers.ModelSerializer):class Meta:model=Publishfields="__all__"depth=1class BookViewSet(APIView):def get(self,request,*args,**kwargs):book_list=Book.objects.all()# 文本類型，這個是和上面的連接有關，后面的參數context,HyperlinkedIdentityField,這個是設置了連接的時候，進行的操作bs=BookSerializers(book_list,many=True,context={'request': request}) return Response(bs.data)def post(self,request,*args,**kwargs):print(request.data)bs=BookSerializers(data=request.data,many=False)if bs.is_valid():print(bs.validated_data)bs.save()return Response(bs.data)else:return HttpResponse(bs.errors)class BookDetailViewSet(APIView):def get(self,request,pk):book_obj=Book.objects.filter(pk=pk).first()bs=BookSerializers(book_obj,context={'request': request})return Response(bs.data)def put(self,request,pk):book_obj=Book.objects.filter(pk=pk).first()bs=BookSerializers(book_obj,data=request.data,context={'request': request})if bs.is_valid():bs.save()return Response(bs.data)else:return HttpResponse(bs.errors)class PublishViewSet(APIView):def get(self,request,*args,**kwargs):publish_list=Publish.objects.all()bs=PublshSerializers(publish_list,many=True,context={'request': request})return Response(bs.data)def post(self,request,*args,**kwargs):bs=PublshSerializers(data=request.data,many=False)if bs.is_valid():# print(bs.validated_data)bs.save()return Response(bs.data)else:return HttpResponse(bs.errors)class PublishDetailViewSet(APIView):def get(self,request,pk):publish_obj=Publish.objects.filter(pk=pk).first()bs=PublshSerializers(publish_obj,context={'request': request})return Response(bs.data)def put(self,request,pk):publish_obj=Publish.objects.filter(pk=pk).first()bs=PublshSerializers(publish_obj,data=request.data,context={'request': request})if bs.is_valid():bs.save()return Response(bs.data)else:return HttpResponse(bs.errors)

第一代：繼承mixin類編寫視圖

繼承mixins的ListModelMixin，CreateModelMixin等類

from rest_framework import mixins
from rest_framework import genericsclass BookViewSet(mixins.ListModelMixin,   # 查看繼承類mixins.CreateModelMixin, # 添加繼承類generics.GenericAPIView):queryset = Book.objects.all()          # 數據庫serializer_class = BookSerializers     # 序列化類def get(self, request, *args, **kwargs):return self.list(request, *args, **kwargs)def post(self, request, *args, **kwargs):return self.create(request, *args, **kwargs)class BookDetailViewSet(mixins.RetrieveModelMixin,  # 查看單條繼承類mixins.UpdateModelMixin,        # 更新單條繼承類mixins.DestroyModelMixin,       # 刪除單條繼承類generics.GenericAPIView):queryset = Book.objects.all()serializer_class = BookSerializersdef get(self, request, *args, **kwargs):return self.retrieve(request, *args, **kwargs)def put(self, request, *args, **kwargs):return self.update(request, *args, **kwargs)def delete(self, request, *args, **kwargs):return self.destroy(request, *args, **kwargs)

第二代：使用通用的基于類的視圖

通過使用mixin類，我們使用更少的代碼重寫了這些視圖，但我們還可以再進一步。REST框架提供了一組已經混合好（mixed-in）的通用視圖，我們可以使用它來簡化我們的views.py模塊。

from rest_framework import mixins
from rest_framework import genericsclass BookViewSet(generics.ListCreateAPIView):queryset = Book.objects.all()serializer_class = BookSerializersclass BookDetailViewSet(generics.RetrieveUpdateDestroyAPIView):queryset = Book.objects.all()serializer_class = BookSerializersclass PublishViewSet(generics.ListCreateAPIView):queryset = Publish.objects.all()serializer_class = PublshSerializersclass PublishDetailViewSet(generics.RetrieveUpdateDestroyAPIView):queryset = Publish.objects.all()serializer_class = PublshSerializers

第三代：viewsets.ModelViewSet

urls.py:

url(r'^books/$', views.BookViewSet.as_view({"get":"list","post":"create"}),name="book_list"),
url(r'^books/(?P<pk>\d+)$', views.BookViewSet.as_view({'get': 'retrieve','put': 'update','patch': 'partial_update','delete': 'destroy'}),name="book_detail"),

views.py:?

class BookViewSet(viewsets.ModelViewSet):queryset = Book.objects.all()serializer_class = BookSerializers

終極版

urls.py同上

views.py

from rest_framework.routers import DefaultRouterrouter = DefaultRouter()                       # 實例化
router.register(r'school', views.SchoolView)   # 注冊
urlpatterns += router.urls                     # 在urlpatterns中添加
