Uploading Multiple Files using Django rest framework without using Forms

I'm trying to Post, from Postman, multiple files to my django app. I'm not using Forms, and there isn't a UI aspect to my app. Here is a my view class.

class FileUploader(APIView):
    '''
    Rest API for FileUploader
    '''
    permission_classes = (AllowAny,)
    parser_classes = (MultiPartParser, )

    @csrf_exempt
    def post(self, request):
        retval = Response(request.data, status=status.HTTP_201_CREATED)
        logger.info('New post with the following data: {}'.format(request.data))

With this it says, "TypeError: init() missing 3 required positional arguments: 'META', 'input_data', and 'upload_handlers'" If I use FormView, my Post has three keys, two represent files, the last is a string. During debugging my request has no field Data, and FILES is empty, and the POST doesn't have any information. Any pointers would be appreciated. I can upload more if that helps.

It's not a duplicate because he was able to upload multiple files and mine doesn't upload any files. I'm struggling to figure out how to find the files within the request and since they aren't there how to set up the views (and not the serialize) to receive multiple files.

I have the same problems as you.

But this problem cause by my mistake when import package.

I should import MultiPartParser from rest_framework.parsers instead of from django.http.multipartparser

✅Right import

from rest_framework.parsers import MultiPartParser

❌Wrong import

from django.http.multipartparser import MultiPartParser

Write a view class as

from rest_framework.views import APIView
from rest_framework.response import Response


class FileUploader(APIView):
    '''
    Rest API for FileUploader
    '''

    permission_classes = (AllowAny,)

    def post(self, request, *args, **kwargs):
        files_list = request.FILES
        data = request.data
        return Response(data={"files": "{} files uploaded".format(len(files_list)),
                              "data": "{} data included".format(len(data))})

and send it using form-data in POSTMAN Screenshot

change the above code to like below and include header 'Content-Type': 'multipart/form-data' in the request.

class FileUploader(APIView):
    '''
    Rest API for FileUploader
    '''
    permission_classes = (AllowAny,)
    parser_classes = (MultiPartParser, )

    @csrf_exempt
    def post(self, request, *args, **kwargs):
        print(request.data)
        return Response({"message": "success"})
