Enforce unique upload file names using django?

Question

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

Answer 1

How about concatenating the filename with the date / time the photo was uploaded and then using hashlib to create a message digest? That should give you unique filenames.

Alternatively you could re-use a neat little snippet which creates unique filenames and then use the full path to that file as the input to your hash call. That gives you unique constant length strings which you can map to your files.
