The more simplest way is to set UNIQUE to the column of the database you
want it to stay unique. That way a duplicate record will not be inserted
and the insert query will return an error stating "record already exist".
Check how to set your required column(s) "unique". This way is the fastest
Thank you Villas, you've been much helpful

spaces in time, days & class rooms should be automatic, the user should
just select the lecturer, the subject & the period the subject takes
(Double session=2hrs, Single session=1hr) from there after the user submits
that inf
Suggestion:
Your idea of overriding the user's selections with random choices seems
strange.
Why not ask the user to specify a date and then show him which classes are
available nearest that date/time?
He can then choose one of those.

when you have a few records, but very inefficient if you have
thousands/millions. Why not simply query the table? Something like this...
def my_validator(form):
if db((db.lecture.id == form.vars.id) & (db.lecture.lec
