Django S3 uploaded file urls show credentials

django s3 file upload
django imagefield upload_to s3
aws_querystring_auth

I am using django-storages and Amazon S3 for file storages. In my model I have: avatar = models.ImageField(_('Avatar'), upload_to='avatars/profiles/', blank=True, null=True)

The image is uploaded successfully on save, but full url with credentials is saved. In my Retrieve requests/ when I read the url from db via console) I get something like: https://subdomain.amazonaws.com/avatars/profiles/filename.jpg?X-Amz-Algorithm=XXX&X-Amz-Expires=XXX&X-Amz-SignedHeaders=XXXX&X-Amz-Signature=XXXX&X-Amz-Date=XXXXXX&X-Amz-Credential=XXXX

How can I prevent this? I could strip the url before responding, but I do not need and therefore do not want to save them in this format, because all files can be accessed publicly, also no need for credentials. Ps. I though of using the post_save hook but it seemed like a hack to me.
