I'm trying to write a custom validator to use in a form, and I'm thinking
it should be simple but the brick wall is leaving dents on my forehead.
Except for getting the occasional "pretty please fill the form" (as when
reloading the page with F5),
I get "congratulations" in the flash, and neither accepted values nor
rejected values, and the debug stuff doesn't show on the console.
In the samples below, I've hot-wired the form to always produce errors,
except it doesn't. I seem to missing a connecting rod somewhere.
Thanks for your help.

in db.py:
from gluon.validators import Validator
class IS_HEXSTR(Validator):
def __init__(self, format='%c%c%c%c', error_message='must be hex string
like A09F!'):
self.format = format
self.error_message = error_message
def __call__(self, value):
try:
intvalue = int(value, 16)
print "should be valid " + intvalue
return (intvalue, "BURGLE")
except:
print "invalid " + value
return (value, self.error_message)
def formatter(self, value):
return value.upper()
(The import was added after reading
<URL:http://www.web2pyslices.com/slice/show/1586/obligate-a-field-just-in-case-another-one-has-value>)
In my controller:
def activate():
form = FORM('Activation code:',
INPUT(_act1='left', requires=[IS_NOT_EMPTY(), IS_HEXSTR()],
_width=4),
INPUT(_type='submit'))
if form.process().accepted:
response.flash = 'congratulations'
elif form.errors:
response.flash = 'form has errors'
else:
response.flash = 'pretty please fill the form'
return dict(form=form)
and the view is :
{{extend 'layout.html'}}
<h1>Activate Enmotus License</h1>
{{=form}}
<h2>Submitted variables</h2>
{{=BEAUTIFY(request.vars)}}
<h2>Accepted variables</h2>
{{=BEAUTIFY(form.vars)}}
<h2>
Unaccepted variables
</h2>
{{=BEAUTIFY(form.errors)}}
