web2py validators with dependencies using validated data

This example of a validator with dependencies is provided in the web2py book in the chapter, Forms and validators .

def index():
    form = SQLFORM.factory(
        Field('username', requires=IS_NOT_EMPTY()),
        Field('password', requires=IS_NOT_EMPTY()),
        Field('password_again',
              requires=IS_EQUAL_TO(request.vars.password)))
    if form.process().accepted:
        pass # or take some action
    return dict(form=form)

The dependency on password_again is based on the raw input for the password field that is received from the form - request.vars.password .

What is the cleanest way to add a validator that is based on the validated data from a form, eg form.vars.pasword ?

I am thinking in the instance where the value in the field may be sanitised during the validation process (eg, turned to upper case, stripped of leading whitespace, have a checkdigit appended).

In that case, use an onvalidation function.
