z3c.form を使用してフォームを作成していて、CSS クラスをウィジェットに追加したいと考えています。
だから私は css クラスを追加するために upadateWidgets メソッドを定義しようとしていますが、 super() でこのエラーが発生しました:
2012-08-02 16:17:22 ERROR Zope.SiteErrorLog 1343917042.940.871101881907 http://pin:34180/Plone/alger/etape1

TypeError: super(type, obj): obj must be an instance or subtype of type
これはコードです:
from zope import interface, schema
from z3c.form import form, field, button, validator
import zope.component
from bsw.inscription import inscriptionMessageFactory as _
class IEtape1Schema(interface.Interface):
# -*- extra stuff goes here -*-
valide_informations = schema.Bool(
title=u"J'assure avoir pris connaissance de toutes les informations ci-dessus",
description=u'',
required=True,
readonly=False,
default=False,
)
class Etape1(form.Form):
fields = field.Fields(IEtape1Schema)
ignoreContext = True
label = _(u'Etape 1')
description = _(u'')
def updateWidgets(self):
""" Customize widget options before rendering the form. """
super(Etape1, self).updateWidgets()
self.fields['valide_informations'].widget.addClass("myClass")
@button.buttonAndHandler(u'Submit')
def actionSubmit(self, action):
data, errors = self.extractData()
if errors:
self.status = self.formErrorsMessage
return
pass
# Put the action handler code here
class checkBoxValidator(validator.SimpleFieldValidator):
def validate(self, value):
if not value:
raise zope.interface.Invalid(_(u"Vous devez accepter les conditions"))
# Set conditions for which fields the validator class applies
validator.WidgetValidatorDiscriminators(checkBoxValidator, field=IEtape1Schema['valide_informations'])
# Register the validator so it will be looked up by z3c.form machinery
zope.component.provideAdapter(checkBoxValidator)
私はたくさんの例を読んだことがありますが、どこが間違っているのかわかりません...
