Your my_validator function iterates through the whole table. This is OK
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.lecture_time == form
.vars.lecture_time)
).count() >0:
form.errors.lecturer=SPAN("Record already exists", _style="font-weight:
bold;")
