Enforce unique upload file names using django?
As of the writing of this answer it seems like you no longer need to do anything special to make this happen. If you set up a FileField with a static upload_to property, the Django storage system will automatically manage naming so that if a duplicate filename is uploaded, Django will randomly generate a new unique filename for the duplicate.
Works on Django 1.10.
What's the best way to rename photos with a unique filename on the server as they are uploaded, using django? I want to make sure each name is used only once. Are there any pinax apps that can do this, perhaps with GUID?
