Quick explanation of interface with models

[djaychela]

Hi

I've just got this up and running on Django 3.0, and I really like it, but I'm struggling to actually understand how the code interfaces with the django model in the demo. I'm not good with javascript and while I've managed to inject a bit of code into the "template-download" script to list the current files, I'm not sure on how the upload / deletion process works. I'm not expecting a blow-by-blow guide to how it works, but a few pointers in the right direction would really be appreciated.

Thanks!
