Hello,
In the book there is this example :
db.define_table('numbers',
Field('a', 'integer'),
Field('b', 'integer'),
Field('c', 'integer', readable=False, writable=False))
def my_form_processing(form):
c = form.vars.a * form.vars.b
if c < 0:
form.errors.b = 'a*b cannot be negative'
else:
form.vars.c = c
def insert_numbers():
form = SQLFORM(db.numbers)
if form.process(onvalidation=my_form_processing).accepted:
session.flash = 'record inserted'
redirect(URL())
return dict(form=form)
Where "my_form_processing" function is called without bracket and
arguments...
I try to do this that failed :
def my_form_processing(table_name, form):
form.vars.field1 = table_name # I know useless, it just
demonstration for purpose of my question...
...
if form.process(onvalidation=my_form_processing(request.args(0),
form)).accepted:
Then I did :
def my_form_processing(form):
form.vars.field1 = request.args(0)
...
if form.process(onvalidation=my_form_processing).accepted:
That actually works...
I would like to make sure that I understand onvalidation properly...
Is "my_form_processing" just a extension of the "insert_numbers()"
function?
And if so, does it have access to all the same variables
(environnement) of "inser_numbers()"??
Thank you!
Richard
