Anyone had any success with ZCatalog in Zope 3?
Sure. I'm not sure what the problem is but I see you get a lot of
replies. We (Infrae) certainly got it working without having to patch
anything.
Um, the setup code we use it something like:
def _registerUtility(context, class_, interface, name=u''):
if not name:
cname = class_.__name__
else:
cname = name
if name and name in context:
raise ValueError, u'Utility %s already registered!' % name
utility = class_()
context[cname] = utility
registration = UtilityRegistration(name, interface, utility)
key = context.registrationManager.addRegistration(registration)
zapi.traverse(context.registrationManager, key).status = ActiveStatus
return utility
in setup code...
from zope.app.intid.interfaces import IIntIds
from zope.app.catalog.interfaces import ICatalog
from zope.app.intid import IntIds
from zope.app.catalog.catalog import Catalog
_registerUtility(default, IntIds, IIntIds)
_registerUtility(default, Catalog, ICatalog, u'my_catalog')
and then to make indexes registered, something like:
from zope.app import zapi
from zope.app.catalog.field import FieldIndex
catalog = zapi.getUtility(ICatalog, u'my_catalog')
catalog['something'] = FieldIndex('something', ISomeInterface)
_registerUtility is rather messy but it works..
Anyway, once you do get the catalog working, you may want to check out
hurry.query, which makes querying the Zope 3 catalog a lot easier (in my
opinion):
