最近对产品api进行rest改造完毕，就记录下Django中rest-framework的一些基本用法
apiview
- apiview使用
class hellolist(APIView):
def get(self,request):
sni=Snippet.objects.all()
serializer=SnippetSerializer(sni,many=True)
return Response(serializer.data)
def post(self,request):
serializer=SnippetSerializer(data=request.data)
if serializer.is_valid():
serializer.save()
return Response(serializer.data,status=status.HTTP_201_CREATED)
return Response(serializer.errors,status=status.HTTP_500_INTERNAL_SERVER_ERROR)
class hellodetail(APIView):
def get_object(self, pk):
try:
return Snippet.objects.get(pk=pk)
except Snippet.DoesNotExist:
raise Http404
def get(self,request,pk):
snippet = self.get_object(pk)
serializer = SnippetSerializer(snippet)
return Response(serializer.data)
def delete(self, request, pk):
snippet = self.get_object(pk)
snippet.delete()
return Response(status=status.HTTP_204_NO_CONTENT)
def put(self, request, pk, format=None):
snippet = self.get_object(pk)
serializer = SnippetSerializer(snippet, data=request.data)
if serializer.is_valid():
serializer.save()
return Response(serializer.data)
return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
mixin
- mixin使用
class hellolist(mixins.ListModelMixin,mixins.CreateModelMixin,generics.GenericAPIView):
queryset = Snippet.objects.all()
serializer_class = SnippetSerializer
def get(self,request, *args, **kwargs):
return self.list(request, *args, **kwargs) //注意为list
def post(self,request, *args, **kwargs):
return self.create(request, *args, **kwargs) //注意为create 不为post！
class hellodetail(mixins.RetrieveModelMixin,mixins.UpdateModelMixin,mixins.DestroyModelMixin,generics.GenericAPIView):
queryset = Snippet.objects.all()
serializer_class = SnippetSerializer
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)
genertic
- genertic使用
class hellolist(generics.ListCreateAPIView):
queryset = Snippet.objects.all()
serializer_class = SnippetSerializer
class hellodetail(generics.RetrieveUpdateDestroyAPIView):
queryset = Snippet.objects.all()
serializer_class = SnippetSerializer
