Hello Massimo,
Thanks for the reply (and also for the YouTube videos on web2py - the first
one is an awesome introduction to the framework)
Basically, on what I'm trying to do, the user will never input a form.
He will upload a file, which I'll parse and I'll create the form from it.
Maybe I can somehow add the "uniqueness" logic in there by checking first
in the db if such data is already present or not, rather than a "requires"
rule in the db model.
Not sure what's best.
Thanks,
NiKAL
