[Zope3-Users] Zope3 winXP service not working
Hello I installed Zope3 on a Windows XP machine, and configured it as a service. The service is properly registered, and seems to be starting/stopping normally. Nevertheless it's not working: Zope does not listen on 8080 (no python process listening in a netstat output), or any other port. The Zope3 server, started manually (not as a service), works fine. Any idea? Thank you very much Eusebius ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Hi Lorenzo, Cool. Where is the `contained` imported from? There is some magic there because I couldn't get the test to work when creating the FieldIndex in your createIndexes method without it.

Re: [Zope3-Users] adding indexes in a __init__ method
Hi Darryl,
this is how I ended implementing it:
class FilterableContainer(BTreeContainer):
implements(IFilterableContainer)
def __init__(self, catalog=None):
super(FilterableContainer, self).__init__()
self.catalog = contained(LocalCatalog(), self, 'catalog')
def createIndexes(self):
self.catalog['attr1'] = FieldIndex('attr1')
self.catalog['attr2'] = FieldIndex('attr2')
def onFilterableContainerAdded(obj, event):
if IFilterableContainer.providedBy(obj):
obj.createIndexes()
Thanks a lot for your help and suggestions!
Lorenzo

Hi Lorenzo, The key reference adapter can only get a key reference **after** the object is added to the database (because it uses _p_oid). The problem could be fixed with a subscriber to IObjectAddedEvent:: def FilterableContainerInitializationHandler(object, event): """Initialize container after its ObjectAddedEvent.""" # I have checks here too (maybe unecessary) if not IObjectAddedEvent.providedBy(event): return if not IFilterableContainer.providedBy(object): return # whatever needs to be done # self._catalog ...

Hi, I have a special Folder content. When an instance of this class is created I want to create a catalog and an index in its __init__ method. Something like: class FilterableContainer(BTreeContainer): implements(IFilterableContainer) def __init__(self): super(FilterableContainer, self).__init__() self._catalog = LocalCatalog() self._catalog['attr1'] = FieldIndex(field_name='attr1') where LocalCatalog is a subclass of Catalog that only indexes objects that belong to its parent. The problem arises when I add my FieldIndex to my internal catalog. Some events are triggered and at the end I got this exception: File "/opt/Zope-3.2.1/lib/python/zope/app/keyreference/persistent.py", line 41, in __init__ raise zope.app.keyreference.interfaces.NotYet(object) NotYet: It happens because the key reference adaptor to Persistent thinks my FieldIndex object is already stored in the database, which is not the case.

That's correct. That way, for example, you can have an edit form made
from the IZopeDublinCore interface for objects that don't provide this
interface directly. The edit form will instead operate on the adapter,
and therefore actually set the dublin core metadata the right way.

That doesn't make sense. Either your adapter implements the full range
of the form schema (in which case you might want to dispatch the
attribute assignment for certain form fields or not...) or it doesn't
(in which case you have a bug).

The getContext() thing is superfluous. The adaption is much more flexible.
Let's say you have a buddy schema:
class IBuddy(zope.interface.Interface):
first = TextLine(title=_("First name"))
last = TextLine(title=_("Last name"))
email = TextLine(title=_("Electronic mail address"))
address = Text(title=_("Postal address"))
postal_code = TextLine(title=_("Postal code"),
constraint=re.compile("\d{5,5}(-\d{4,4})?$").match)
Now, the edit form for this could be different:
class IBuddyForm(IBuddy):
# also allow city to be entered, we deduce postal_code
# from that
city = TextLine(title=_("City"))
Now, buddies don't provide IBuddyForm, they only provide IBuddy. Hence
we need an adapter:
class BuddyFormAdapter(object):
adapts(IBuddy)
implements(IBuddyForm)
def __init__(self, context):
self.context = context
# account for everything in the IBuddy interface
for field in IBuddy:
locals()[field] = property(
lambda self: getattr(self.context, field),
lambda self, value: setattr(self.context, field, value)
)
# account for additional stuff in IBuddyForm
def getCity(self):
return getCityFromPostalCode(self.postal_code)
def setCity(self):
postal_code = getPostalCodeFromCity(city)
self.postal_code = postal_code
city = property(getCity, setCity)
