一、基本视图

写一个出版社的增删查改resful接口

要自己事先创建好django项目，并创建好表，添加完记录

路由：

url(r'^publish/$', views.PublishView.as_view()),
url(r'^publish/(?P<pk>\d+)/$', views.PublishDetailView.as_view()),

视图：

from api import modelsfrom rest_framework import serializersfrom rest_framework.response import Responsefrom rest_framework.views import APIViewclass PublishSerializers(serializers.ModelSerializer): class Meta: model=models.Publish fields='__all__'class PublishView(APIView):　　#查询出版社表中所有记录 def get(self, request): publish_list = models.Publish.objects.all() bs = PublishSerializers(publish_list, many=True) # 序列化数据 return Response(bs.data) #返回的结果是列表中套字典　　 def post(self, request): # 添加一条数据 print(request.data) bs=PublishSerializers(data=request.data) if bs.is_valid(): bs.save() # 生成记录 return Response(bs.data) #返回的是添加成功记录的字典 else: return Response(bs.errors)class PublishDetailView(APIView):　　 #查询某一条数据 def get(self,request,pk): publish_obj=models.Publish.objects.filter(pk=pk).first() bs=PublishSerializers(publish_obj,many=False) return Response(bs.data)　　 #更新某一条数据 def put(self,request,pk): publish_obj = models.Publish.objects.filter(pk=pk).first() bs=PublishSerializers(data=request.data,instance=publish_obj) if bs.is_valid(): bs.save() # update return Response(bs.data) else: return Response(bs.errors)　　 #删除某一条数据 def delete(self,request,pk): models.Publish.objects.filter(pk=pk).delete() return Response("")

二、mixins类和generic类编写视图

路由：

url(r'^publishes$', views.Publish.as_view()),
url(r'^publish/(?P<pk>\d+)', views.PublishDetail.as_view()),

视图：

from api import modelsfrom rest_framework import serializersfrom rest_framework import mixinsfrom rest_framework.generics import GenericAPIViewclass PublishSer(serializers.ModelSerializer): class Meta: model=models.Publish fields='__all__'class Publish(GenericAPIView,mixins.ListModelMixin,mixins.CreateModelMixin): queryset = models.Publish.objects.all() serializer_class = PublishSer def get(self,request): return self.list(request) #在ListModelMixin下有一个list方法，返回的就是查询的结果:Response(serializer.data) def post(self,request): return self.create(request) #已经封装好了，帮我们做校验和序列化，返回的是添加成功的记录class PublishDetail(GenericAPIView,mixins.DestroyModelMixin,mixins.RetrieveModelMixin,mixins.UpdateModelMixin): queryset = models.Publish.objects.all() serializer_class = PublishSer def 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)

三、使用generic下ListCreateAPIView和RetrieveUpdateDestroyAPIView

路由：

url(r'^publishes$', views.Publish.as_view()),
url(r'^publish/(?P<pk>\d+)', views.PublishDetail.as_view()),

视图：

from api import modelsfrom rest_framework import mixinsfrom rest_framework.generics import GenericAPIViewfrom rest_framework.generics import ListCreateAPIView,RetrieveUpdateDestroyAPIViewfrom rest_framework import serializersclass Publishser(serializers.ModelSerializer): class Meta: model=models.Publish fields='__all__'class Publish(ListCreateAPIView): queryset = models.Publish.objects.all() serializer_class = Publishserclass PublishDetail(RetrieveUpdateDestroyAPIView): queryset = models.Publish.objects.all() serializer_class = Publishser

四、使用ModelViewSet

路由：

url(r'^publish$',views.Publish.as_view({'get':'list','post':'create'})),
url(r'^publish/(?P<pk>\d+)', views.Publish.as_view({'get': 'retrieve', 'put': 'update', 'delete': 'destroy'})),

视图：

from rest_framework.viewsets import ModelViewSetfrom api import modelsfrom rest_framework import serializersclass Publishser(serializers.ModelSerializer): class Meta: model=models.Publish fields='__all__'class Publish(ModelViewSet): queryset = models.Publish.objects.all() serializer_class = Publishser
