Rename key using boto3 within the same s3 bucket

Question

I'm trying to re-key uploaded files so that they move from a 'temp-uploads' "folder" to a 'new-uploads' "folder.

This is my attempt thus far --- I get no error, but the files are still in 'temp-uploads'

  bucket = s3.Bucket(s3_bucket)
    temp_prefix = 'temp-uploads/' + packageInstance.prefix + '/'
    new_prefix = 'new-uploads/' + packageInstance.prefix + '/'
    for obj in bucket.objects.filter(Prefix=temp_prefix):
        old_source = {'Bucket': bucket,
                      'Key': obj.key}
        new_key = obj.key.replace(temp_prefix, new_prefix)
        new_obj = bucket.Object(new_key)
        new_obj.copy(old_source)

Answer 1

This seems to copy the actual file from temp-uploads/ to new-uploads/ , so the old file still exists in the old location.

Then, files uploaded by Django are stored as a reference in a FileField . That means Django generates an URL from a previously uploaded file. If the file is moved on the bucket outside of Django, it has no way to know it happened.
