Hi,
the proposed solution kind of works. It now indeed gives the message
that a field is empty, but unfortunately also resets the form.
I don't know if this is the result of populating the form from a DB, I
didn't really look into it.
But this seems to work as expected:
# -*- coding: utf-8 -*-
""" root form: form on the first page """
from tw.api import WidgetsList
from formencode.api import NoDefault
from tw.forms import TableForm, MultipleSelectField, CheckBoxTable
from tw.forms.validators import Int, ForEach, OneOf
class RootForm(TableForm):
class fields(WidgetsList):
annotation_options = [u'transcripts', u'genes', u'proteins']
types = MultipleSelectField(
label_text = 'Type',
help_text = 'Please select one or more experiment types',
validator = ForEach(Int, if_missing=NoDefault)
)
annotations = CheckBoxTable(
options = annotation_options,
label_text = 'Annotations',
help_text = 'Please select one or more of the annotation
types',
validator = ForEach(OneOf(annotation_options),
if_missing=NoDefault)
)
timepoints = CheckBoxTable(
label_text = 'Timepoints',
help_text = 'Please select timepoints',
validator = ForEach(Int, if_missing=NoDefault)
)
submit_text = 'Go!'
hover_help = True
show_errors = True
action = 'overview'
root_form = RootForm('root_form')
Thx for the hint,
Kenny
