The following worked for me  based on example for a Django model  but you can pretty much use the code of the delete method on its own    import boto3 from boto3 session import Session from django conf import settings  class Video models Model       title models CharField max length 500      description models TextField default         creation date models DateTimeField default timezone now      videofile models FileField upload to  videos    null True  verbose name         tags   TaggableManager        actions     delete        def   str   self           return self title          str self videofile       def delete self   args    kwargs           session   Session  settings AWS ACCESS KEY ID  settings AWS SECRET ACCESS KEY          s3 resource   session resource  s3           s3 bucket   s3 resource Bucket settings AWS STORAGE BUCKET NAME           file path    media     str self videofile          response   s3 bucket delete objects              Delete                    Objects                                                    Key   file path                                                                super Video  self  delete  args    kwargs
