    BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))    STATIC_URL = '/static/'    MEDIA_URL = 'Media/'    MEDIA_ROOT = os.path.join(BASE_DIR, MEDIA_URL)

I want to save the file in my media folder for this I'm using

    excel_name_sheet = settings.MEDIA_URL+'upload_csv_file/'+ str(request.FILES['upload_bulk_data'])    SaveCsvSheet.save_file(request, request.FILES['upload_bulk_data'], settings.MEDIA_URL  +'upload_csv_file')

I have took file using form which I got in request.FILES['upload_bulk_data']
