django-storages with Amazon S3 - prevent overwriting

Question

I noticed that django-storages (or perhaps it's Django's storage API itself) overwrites files with the same name. This is a problem for me as my site allows user uploads, so I need to ensure that files are never overwritten.

Ideally, I'd like to be able to pass a file name to the storage backend from the view level, but I'm struggling to find an elegant way to do this. I'd be equally happy if there's a switch somewhere where I can just do something like overwrite=False and have the backend come up with its own alternative name.

You can change this using AWS_S3_FILE_OVERWRITE setting: https://bitbucket.org/david/django-storages/src/83fa2f0ba20c/storages/backends/s3boto.py#cl-43
