Re: [Zope3-Users] Selectwidgets (Object is of wrong type)
You are probably experiencing a ValidationError in the .validate() method of
your "language" field. This is probably because TextLine expect the values
to be unicode whereas the vocabulary in your widget has (8-bit) string
values ("voc = SimpleVocabulary.fromItems([('de','German'),
('en','English')])".

[Zope3-Users] Selectwidgets (Object is of wrong type)
Hi!
I'm having serious problems with getting a selectwidget/
dropdownwidget working..
What I want to do is to add a widget for the language field of a
MessageCatalog.
Btw, a snippet from the interface (in zope.app.i18n.messagecatalog):
class IMessageCatalog(Interface):
#...
language = TextLine(
title=u"Language",
description=u"The language the catalog translates to.",
required=True)
#...
I already have an add view working but instead of manually filling in
'en' for english,
'de' for german, etc. I now have a widget that generates this:
English
German
But the thing is, I keep getting "Language: Object is of wrong
type." displayed to me
when I click the add button (i.e no system error). Here's the code:
-
class MessageCatalogAddForm(AddForm):
form_fields = Fields(IMessageCatalog)
label = _(u'Add message catalog')
form_fields['language'].custom_widget = LanguageDropDown
def create(self, data):
msgcat = MessageCatalog(data['language'], data['domain'])
return msgcat
-
class LanguageDropDown(DropdownWidget):
def __init__(self, field, request):
# Simple test to begin with, will use locale when i get this working..
voc = SimpleVocabulary.fromItems([('de','German'),
('en','English')])
super(LanguageDropDown, self).__init__(field, voc, request)
# Display the readable version, German & English instead of de
& en
def textForValue(self, term):
return term.value
-
I think I'm missing something or doing something wrong in
LanguageDropdown.__init__
Where does the constraint get checked for this Widget? I keep getting
"Object is of wrong type" but i can't
find in what function this is generated.
With kindest regards
