Note, you have not created the requires_date function so that it acts as a
validator -- rather, when called, it merely returns an instance of a
validator. So, you must actually call it above:
clear enough for callback function, thank you so much for detail
explaination, anthony, better to move it to modules, it didnt appear in
snakeviz result when it's not called
for current i understand the reason, but when i move it to lambda or
function without arguments, it return an error.

a, i c, my assumption is whatever showed in snakeviz result, is all the
python files that executed, btw, there still odd for me, why login_onfail
callback function is not showed snakeviz, wheter it's executed or defined?

Line 3 is the line where the before_insert_person function is *defined, *not
where it is *called*. The output does not indicate the function has
actually been called.

ok, i tried to minimalized the scope (start from simple scratch)
*1. copy welcome scaffolding app*
cp -R ~/site/web2py/applications/welcome/ ~/site/web2py/applications/z
*2. Run Web2py with profiler*
source ~/site/bin/activate
python ~/site/web2py/web2py.py --nogui --no-banner -a 'a' -i 0.0.0.0 -p

btw, your explaination about login_onfail is clear enough, but when compare
to the 2nd example, i've bit confused :
assuming the login_onfail is the callback function and not executed when
it's hit login screen
What do you mean by the word "loaded"? Are you expected these functions to
be executed? They are callback functions that are only executed in
particular cases. For example, login_onfail will only be executed upon a
failed login attempt. A table's on_define will be executed when it is fully
10 matches
