406 Not Acceptable while uploading files

[Kamilla Holanda]

Hey there!

I am working on a file upload functionality and right now I'm stucked on a weird problem. I am always getting the error:

------------------------------------------------------------------------------
{"errors":[{"detail":"Could not satisfy the request Accept header.","status":"406","source":{"pointer":"/data"},"code":"not_acceptable"}]}

------------------------------------------------------------------------------

When I am sending the following request:

------------------------------------------------------------------------------

POST /aposento-fotos/ HTTP/1.1
Host: localhost:8000
Connection: keep-alive
Content-Length: 24364

------------------------------------------------------------------------------


I am getting the following response:


------------------------------------------------------------------------------
HTTP/1.1 406 Not Acceptable

------------------------------------------------------------------------------

I have read about the DRF Parsers and tried it all. Nothing is working for my view:

------------------------------------------------------------------------------

class MyUploadViewSet(ModelViewSet):

    queryset = Photos.objects.all()

    serializer_class = PhotosSerializer

    permission_classes = [IsOwnerOrAdminUser]

    parser_classes = [MultiPartParser,

                      FormParser, JSONParser, FileUploadParser]

------------------------------------------------------------------------------

It only works when I use a generic view:

------------------------------------------------------------------------------

class MyUploadView(View):

  def get(self, request, **kwargs):

        print(request)

        print(request.method)

        print(request.GET)

    def post(self, request, **kwargs):
         pass

------------------------------------------------------------------------------

But I want to get it working with the ModelViewSet.

Does anybody know how could I get it working with ModelViewSet? I think it's not working because the request Content-Type, but It was supposed to work with a Parser, right? I am really confused and would appreciate any help.
Thank you in advance.

Hi there. I'm not quite sure if this will solve the issue, but vou should be handling the upload as a post request.

@Wandss Thank you for your answer! 

I am not sure If I understood what you mean. My client is an EmberJS app and it fires a post request to upload the file and I think that the ViewSet action to deal with a post request is the "create" action, right? Should I deal with it using other action?

[Wanderley S]

In your code I just saw this part:

class MyUploadView(View):

  def get(self, request, **kwargs):

        print(request)

        print(request.method)

        print(request.GET)

    def post(self, request, **kwargs):
         pass

Did you try this?

class PhotoAlbumCreateAPIView(CreateAPIView):

    serializer_class = PhotoAlbumSerializer

    queryset = PhotoAlbum.objects.all()

Just tried and now I'm getting this error:

AttributeError: type object 'AposentoFotoViewSet' has no attribute 'get_extra_actions'

I have changed the code to:

-------------------------------------------------------------------

from rest_framework.generics import CreateAPIView

class PhotoAlbumViewSet(CreateAPIView):

    queryset = PhotoAlbum.objects.all()

    serializer_class = PhotoAlbumSerializer

    def post(self, request, *args, **kwargs):

        print("CREATE Photos")

-------------------------------------------------------------------

Is that the right package?

[Kamilla Holanda]

I have changed the url to:

    path('photos/', PhotoAlbumViewSet.as_view(), name='photos'),

And it solved the error that I mentioned above.

But now I'm still getting the 406 Not Acceptable error:

{"errors":[{"detail":"Could not satisfy the request Accept header.","status":"406","source":{"pointer":"/data"},"code":"not_acceptable"}]}

According to the error details, seems that your hearder is not correct at client side. 

You can try to use the browseable API from DRF for testing. After that I suggest you to review your front end.

Are you using axios for handling the API  requests?

I wasn't able to get the ModelViewset working for uploading files so I changed my approach and used one dedicated endpoint to upload files and kept the other models as regular models. Not sure if it's the best approach but I need to move fast on these features.

Thank you for your help!
