DRF File Upload, How can I solve File missing Error? - django

Question

400 Error
{"detail":"Missing filename. Request should include a Content-Disposition header with a filename parameter."}
I want to upload file via DRF FileUploadParser
But Error occurs below
Bad Request: /api/activities/40/chapter/1/upload
[09/Nov/2021 16:44:33] "POST /api/activities/40/chapter/1/upload HTTP/1.1" 400 109
And my codes in views.py about that error are this.
class FileView(APIView):
parser_classes = (FileUploadParser,)
def post(self, request, format=None, *args, **kwargs):
if 'file' not in request.FILES:
raise ParseError("Empty content")
f = request.FILES.get('file')
print(f)
print(dir(request))
print(request.__dict__)
addAttr = request.data.dict()
file_name = request.data['filename']
new_file_full_name = file_upload_path(file_name.name)
file_path = '/'.join(new_file_full_name.split('/')[0:-1])
#model Attr
addAttr['activityid'] = request.parser_context['kwargs']['pk']
addAttr['chapterid'] = request.parser_context['kwargs']['chapterid']
addAttr['filepath'] = file_path
addAttr['filename'] = file_name
addAttr['fileext'] = os.path.splitext(file_name.name)[1]
addAttr['create_date'] = datetime.datetime.now()
addAttrDict = QueryDict('', mutable=True)
addAttrDict.update(addAttr)
fileSerializer = ChapterfileSerializer(data = addAttrDict, files=request.FILES)
if fileSerializer.is_valid():
fileSerializer.save()
print(fileSerializer.data)
return Response(status=status.HTTP_201_CREATED)
else:
print(fileSerializer.errors)
return Response(fileSerializer.errors, status=status.HTTP_400_BAD_REQUEST)
If I add a parameter "filename", 500 error occured.
TypeError: post() missing 1 required positional argument: 'parameter'
[09/Nov/2021 16:48:35] "POST /api/activities/40/chapter/1/upload HTTP/1.1" 500 86716
ReactJS page sends File to my Django API Server.
activityid and chapterid are Board and Post ID.
SO, I need these insert to DB.
How can I solve this?

Use the FileUploadParser, it's all in the request. Use a put method instead, you'll find an example in the docs :)
class FileUploadAPIView(views.APIView):
parser_classes = (FileUploadParser,)
def put(self, request, filename, format=None):
file_obj = request.FILES['file']
# Do some stuff with the uploaded file
return Response({'details': 'Your file uploaded successfully.'}, status=204)
