[web2py] how to avoid an overhead

[Martin Weissenboeck]

I have a fundamental question. Let's say I have a function like

def mypage():
    form = a_lot_of_calculations_and_db_accesses()
    if form.process().accepted:
        do_something()
    return dict(form=form)

The part a_lot_of_calculations_and_db_accesses() runs twice: first time to
prepare the page and a second time to handle the responses. Is there any
way to avoid these double call of a_lot_of_calculations_and_db_accesses()?

Regards, Martin
