hi Kenny,
My idea is to validate your form with formencode.Schema, This is a
peace of code that work for me :
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):
.... and your code ...
But, for me validators should check any case of user entry, so this
one should be the best in you case in my mind :
from formencode.foreach import ForEach
from formencode.validators import OneOf
from formencode import Schema
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
