Is there a comprehensive guide to doing validators? The website just
has a few examples of magic incantations :)

'Solve it,
Add the following line before "register_form =...."
v = [form.Validator("Check more than 3", lambda x: len(x.check)>3)]
Then modify line "register_form= ....."
register_form = form.Form(validators=v, *args)
to add the validator.
Then modify line: "if not f.validates():"
if not f.validates(web.input(check=[])):
to pass the submited data and validate it.
Hope this helps. I was searching the net for a "quick" solution but
could not find one.

Hello,
I need to validate a form only if X or more checkboxes were
checked and I cannot find out how. Bellow is the simple code which
needs the validator (there are 5 checkboxes - same name - and the
form should validate only if 3 or more were selected). Can you
please point me to the right direction?
import web
from web import form
render = web.template.render('templates/')
urls = ('/', 'index')
app = web.application(urls, globals())
args = ()
for i in range(0, 5):
args = args + ( form.Checkbox('check', value=str(i) ), )
args = args + (form.Button("submit", type="submit",
description="Submit"),)
register_form = form.Form(*args)
class index:
def GET(self):
# do $:f.render() in the template
f = register_form()
return render.register(f)
def POST(self):
f = register_form()
if not f.validates():
return render.register(f)
else:
pdata=web.input(check=[])
print pdata
if __name__=="__main__":
web.internalerror = web.debugerror
app.run()
