How to add multiple onvalidation

[Rahul]

Hi All,

         It may be simple one but I want to know how to add multiple onvalidation functions/methods in my code. For example If I want to check for userlimit reached for users before adding one as well as want to check for duplicate users for the same form which exists in other function. 

form = SQLFORM(db.numbers)

if form.process(onvalidation=my_form_processing).accepted:

      do something .... 

def my_form_processing(form): 

       do something ... 

Regards,

Rahul

Nevermind, 

           I was able to achieve that using nested functions. Thanks!
