Hi Kenny,
My idea is to use formencode.Schema to validate your form.
from tw.forms.validators import NotEmpty,
from formencode import Schema
class ValidateAnswer(Schema):
filter_extra_fields = True
allow_extra_fields = True
annotations_widget= NotEmpty
class RootForm(TableForm):
validator = ValidateAnswer
class fields(WidgetsList):
value_types_widget = MultipleSelectField(..
....
In another hand, the aim form validators is to check all possible case
so, for me the best way is following
from formencode import Schema
from formencode.foreach import ForEach
from formencode.validators import OneOf
class ValidateAnswerBest(Schema):
filter_extra_fields = True
allow_extra_fields = True
AvailableOptions = ['transcripts', 'genes', 'proteins']
annotations_widget= All(chained_validators=[ NotEmpty,
ForEach(OneOf(AvailableOptions)) ])
Regards.
