Django Rest Framework File Upload

I am using Django Rest Framework and AngularJs to upload a file. My view file looks like this:

class ProductList(APIView):
    authentication_classes = (authentication.TokenAuthentication,)
    def get(self,request):
        if request.user.is_authenticated(): 
            userCompanyId = request.user.get_profile().companyId
            products = Product.objects.filter(company = userCompanyId)
            serializer = ProductSerializer(products,many=True)
            return Response(serializer.data)

    def post(self,request):
        serializer = ProductSerializer(data=request.DATA, files=request.FILES)
        if serializer.is_valid():
            serializer.save()
            return Response(data=request.DATA)

As the last line of post method should return all the data, I have several questions:

  • how to check if there is anything in request.FILES?
  • how to serialize file field?
  • how should I use parser?

Answer

Use the FileUploadParser, it’s all in the request. Use a put method instead, you’ll find an example in the docs 🙂

class FileUploadView(views.APIView):
    parser_classes = (FileUploadParser,)

    def put(self, request, filename, format=None):
        file_obj = request.FILES['file']
        # do some stuff with uploaded file
        return Response(status=204)
