Hi,
I've recently started a small project using turbogears and I ran into
a problem that I believe from what I found so far can best be solved
by using a form validator.
Only I can't figure out how to add a validator to my form. And so far
I've been unable to find a tutorial or other documentation that
explains this on a level I can grasp it.
The problem at hand is that I've created a multi select on a form (in
one of the templates) and I want to make sure that for this parameter
is returned as a list even when only one option is selected.
According to
https://groups.google.com/group/turbogears/browse_thread/thread/9ad78837dcd9ac5f?fwc=1&hl=hy
I should use a validator for this.
I've read http://turbogears.org/2.0/docs/main/Validation.html but to
me that's a giant leap from the 20-minutes wiki tutorial and I can't
figure out what to add to the controller, what to add to the template,
what to import etc.
http://www.turbogears.org/2.0/docs/main/ToscaWidgets/Cookbook/PasswordValidation.html
also appears to rely on background knowledge I haven't picked up yet.
Can someone point me to some documentation to help me with this?
I'm not aware of "better" docs here, I don't read docs that much these
days ;)
This applies to your issue:
http://turbogears.org/2.0/docs/main/Validation.html#validating-arguments-without-form-widgets
Your code should look roughly like this (only focussing on the
differences to your current setup):
from tg import validate
from formencode import ForEach
from formencode.validators import Int
@expose(...)
@validate(dict(my_param=ForEach(Int(not_empty=True),
convert_to_list=True))
def my_action(...):
HTH,
Diez
