DRF request.data issue with POST method - django-rest-framework

Question

I'm using DRF to test a api,when i POST a data,DRF return status_code 500 and error 'MacList' object has no attribute 'data'. but the GET is not problem.
Views:
class MacList(mixins.ListModelMixin,mixins.CreateModelMixin,generics.GenericAPIView):
queryset = Testable.objects.all()
serializer_class = TestableSerializer
def get(self,request,*args,**kwargs):
return self.list(self, request, *args, **kwargs)
def post(self,request,*args,**kwargs):
return self.create(self, request, *args, **kwargs)
URLs:
path(r'api/maclist',views.MacList.as_view())
I'm checking the mixins.CreateModelMixin source code
class CreateModelMixin:
"""
Create a model instance.
"""
def create(self, request, *args, **kwargs):
serializer = self.get_serializer(data=request.data) **#### problem here**
serializer.is_valid(raise_exception=True)
self.perform_create(serializer)
headers = self.get_success_headers(serializer.data)
return Response(serializer.data, status=status.HTTP_201_CREATED, headers=headers)
def perform_create(self, serializer):
serializer.save()
def get_success_headers(self, data):
try:
return {'Location': str(data[api_settings.URL_FIELD_NAME])}
except (TypeError, KeyError):
return {}
if i use APIView to POST success.
class MacList(APIView):
def post(self,request):
serializer = TestableSerializer(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_400_BAD_REQUEST)
Please help me!

Don't need to pass derived class instance into inherited class method while calling it from derived class, when we use self python automatically pass this instance
It will works if you change your code to
.
.
def get(self,request,*args,**kwargs):
return self.list(request, *args, **kwargs)
def post(self,request,*args,**kwargs):
return self.create(request, *args, **kwargs)
