FileUploadParser doesn't get the file name

In django REST framework. we have components like Parsers, Renderers and Serializers.

• The responsibility of Parsers is to parse the data that is sent by request methods GET, POST and PUT, etc.

• Default parser used in django REST is 'JSONParser'. It only parses the data JSON data[numbers, string, date]. It ignores the data like FILES.

• In order to parse the FILES we need to use parsers like "MultiPartParser" or "FormParser".

  Example Code :

      from rest_framework.parsers import MultiPartParser
      from rest_framework.response import Response
      from rest_framework.views import APIView
  
      class ExampleView(APIView):
          """
          A view that can accept POST requests with JSON content.
          """
          parser_classes = (MultiPartParser,)
  
          def post(self, request, format=None):
              # to access files
              print request.FILES
              # to access data
              print request.data
              return Response({'received data': request.data})
  

When we use property request.data then parser will parse the data.

I face the same problem.The problem error message shows:

{"detail":"Missing filename. Request should include a Content-Disposition header with a filename parameter."} I do all the steps above my answer but it doesn't work.Finally,

I find the reason is in the backend of viewset.

it shows like this

parser_classes = (FileUploadParser, MultiPartParser, FormParser)

and I remove the FileUploadParser

  parser_classes = ( MultiPartParser, FormParser)

and It works, so I think you should pay more attention to it
