I'm starting a new project to extend Plone news items and include a
bunch of new fields in order to support something called NITF (News
Industry Text Format) using schemaextender.
I installed schemaextender on "lib/python" using "setup.py install"
I have this on extender.py:
from archetypes.schemaextender.interfaces import ISchemaExtender
from archetypes.schemaextender.field import ExtensionField
from Products.Archetypes.public import BooleanField, BooleanWidget
from Products.ATContentTypes.interface import IATNewsItem
from zope.component import adapts
from zope.interface import implements
class UrgencyField(ExtensionField, BooleanField):
"""Urgency field
"""
class NITFExtender(object):
"""Adapter to add NITF fields to News Items
"""
adapts(IATNewsItem)
implements(ISchemaExtender)
fields = [
UrgencyField('urgency',
widget = BooleanWidget(
label='Is this item urgent?')),
]
def __init__(self, context):
self.context = context
def getFields(self):
return self.fields
and I have this on configure.zcml:
<include package="archetypes.schemaextender" />
<adapter factory=".extender.NITFExtender" />
when I add a new item I don't see my new field
I'm using the zope3 interface for IATNewsItem.
I'm using schemaextender from trunk.
my product's code is here:
http://dev.plone.org/collective/browser/nitf4plone/trunk
(I used code from WebLion's guys to install it.)
any hint?
I don't think archetypes.schemaextender will work with anything prior to
Plone 3 (or more specifically, Archetypes 1.5).
