model:
class IS_LIST_TAGS:
def __init__(self, separator=',', error_message='too many tags max=3
tags!'):
self.separator = separator
self.e = error_message
def __call__(self,value):
try:
li = value.split(self.separator)
assert(len(li) <= 3)
return (li, None)
db.define_table('listr',
Field('tags','list:string',requires=[IS_NOT_EMPTY(),
IS_LIST_TAGS()]))
controller:
def test():
form = SQLFORM(db.listr)
if form.process().accepted:
response.flash = 'form accepted'
