路由：
url(r‘^publish/$‘, views.PublishView.as_view()), url(r‘^publish/(?P<pk>\d+)/$‘, views.PublishDetailView.as_view()),
视图：
class PublishSerializers(serializers.ModelSerializer): class Meta: model=models.Publish fields=‘__all__‘ class PublishView(APIView): #查询所有出版社 def get(self, request): publish_list = models.Publish.objects.all() res = PublishSerializers(publish_list, many=True) # 序列化数据 return Response(res.data) #增加出版社 def post(self, request): # 添加一条数据 print(request.data) res=PublishSerializers(data=request.data) if res.is_valid(): res.save() # 生成记录 return Response(res.data) else: return Response(res.errors) class PublishDetailView(APIView): #查询单个出版社 def get(self,request,pk): publish_obj=models.Publish.objects.filter(pk=pk).first() res=PublishSerializers(publish_obj,many=False) return Response(res.data) #修改出版社 def put(self,request,pk): publish_obj = models.Publish.objects.filter(pk=pk).first() res=PublishSerializers(data=request.data,instance=publish_obj) if res.is_valid(): res.save() # update return Response(res.data) else: return Response(res.errors) #删除出版社 def delete(self,request,pk): models.Publish.objects.filter(pk=pk).delete() return Response("")
对应源码配置参数： queryset=models.Publish.objects.all() #指定queryset对象 和对应的serializer类 serializer_class=PublishSerializers

路由：路由中有名分组的名字必须指定为pk
url(r‘^publish/$‘, views.PublishView.as_view()), url(r‘^publish/(?P<pk>\d+)/$‘, views.PublishDetailView.as_view()),
视图：
from rest_framework.generics import ListCreateAPIView,RetrieveUpdateDestroyAPIView class PublishView(ListCreateAPIView): #ListCreateAPIView类里包含get和post接口 queryset=models.Publish.objects.all() serializer_class=PublishSerializers class PublishDetailView(RetrieveUpdateDestroyAPIView): #RetrieveUpdateDestroyAPIView类里包含get、put、delete接口 queryset=models.Publish.objects.all() serializer_class=PublishSerializers
路由：路由中有名分组的名字必须指定为pk
url(r‘^publish/$‘, views.PublishView.as_view({‘get‘:‘list‘,‘post‘:‘create‘})), url(r‘^publish/(?P<pk>\d+)/$‘,views.PublishView.as_view({‘get‘:‘retrieve‘,‘put‘:‘update‘,‘delete‘:‘destroy‘})),
视图：
from rest_framework.viewsets import ModelViewSet class PublishView(ModelViewSet): #ModelViewSet类里囊括了get、post、get、put、delete这五个接口 queryset=models.Publish.objects.all() serializer_class=PublishSerializers
ModelViewSet类继承了ViewSetMixin类，所以可以通过路由响应到不同的函数
ViewSetMixin源码分析：
重写as_view()方法，可以给as_view()传参
