基本视图
写一个出版社的增删查改resful接口
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): 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) 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) else: return Response(bs.errors) class PublishDetailView(APIView): def get(self,request,pk): publish_obj=models.Publish.objects.filter(pk=pk).first() bs=PublishSerializers(publish_obj,many=False) return Response(bs.data) 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) def delete(self,request,pk): models.Publish.objects.filter(pk=pk).delete() return Response("")
mixin类和generice类编写视图
from rest_framework.mixins import CreateModelMixin,RetrieveModelMixin,ListModelMixin,UpdateModelMixin,DestroyModelMixin from rest_framework.generics import GenericAPIView class PublishView(ListModelMixin,CreateModelMixin,GenericAPIView): queryset=models.Publish.objects.all() serializer_class=PublishSerializers def get(self, request): return self.list(request) def post(self, request): return self.create(request) class PublishDetailView(RetrieveModelMixin,UpdateModelMixin,DestroyModelMixin,GenericAPIView): queryset=models.Publish.objects.all() serializer_class=PublishSerializers 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)
使用generics 下ListCreateAPIView,RetrieveUpdateDestroyAPIView
from rest_framework.generics import ListCreateAPIView,RetrieveUpdateDestroyAPIView class PublishView(ListCreateAPIView): queryset=models.Publish.objects.all() serializer_class=PublishSerializers class PublishDetailView(RetrieveUpdateDestroyAPIView): queryset=models.Publish.objects.all() serializer_class=PublishSerializers
使用ModelViewSet
路由:
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): queryset=models.Publish.objects.all() serializer_class=PublishSerializers
