If your class is subclassed from ObjectManager, just use objectValues(spec="SREventPost") -jfarr ----- Original Message ----- From: ed colmar <element@immersivearts.com> To: <zope@zope.org> Sent: Friday, April 14, 2000 7:22 AM Subject: [Zope] filter(), map(), and lambda
Hey all!
I've been trying to achieve this for a few months now, with no success. hopefully someone will be able to shed some light on this one...
I have a python product that contains 3 sub-classes. One of these is called "events". In my primary class I have a method "eventValues", which works great to return sub objects, but It also returns sub-objects that are NOT events.
------------------
def eventValues(self): """ return list of sub-objects """ return map(lambda x, p=self: x.__of__(p), self.data.map(self.ids))
------------------ So, I tried adding in a filter() to remove out the meta_types that I don't want. ------------------
def eventFilterValues(self): """ return list of only events """ rlist = map(lambda x, p=self: x.__of__(p), self.data.map(self.ids)) rlist = filter(lambda x,p=self : p.data[x].meta_type == 'SREventPost', rlist) return rlist
------------------
These calls are not working... I get a TypeError
Error Type: TypeError Error Value: Bucket __getitem__ expected integer key
Any ideas how to make this work?
