Massimo, that gave me a ticket with this:
Traceback (most recent call last):

newstatus = self._validate()
File "C:\repo\anima\gluon\html.py", line 1300, in _validate
(value, errors) = validator(value)
ValueError: too many values to unpack
But I had already succeed with this:
class TAGS_LIST:
def __init__(self, separator=',', error_message='This is not a
valid list!'):
self.separator = separator
self.e = error_message
def __call__(self,value):
try:
list = value.split(self.separator)
return (list, None)
except:
return (value, self.e)
def formatter(self, value):
tags = ''
for tag in value:
tags += '%(tag)s%(sep)s ' %
{'tag':tag,'sep':self.separator}
return tags
I have two question:
Could this be general relating different DBs?
Is there a way to define a default widget for a custom validator?
