Prepend timestamp onto uploaded filenames #9

Closed danstowell closed 7 years ago

To ensure unique filenames.

At present filename is not unique. I see that one user has uploaded "fusion.csv" at least 3 times, and presumably the latest file overwrites, since they're going to the same folder? So this is a problem if we need to access those files.

This simple-minded fix puts the timestamp onto the start of the filename. (Neater would be to use the submission ID number, but that is not known until after the db commit.)

A better option to generate unique filenames is, in my opinion, to use uuid:

import uuid
filename = str(uuid.uuid4())

OK - that would be fine with me
