Yep.

Ok. I'm not saying that this is the "right" way; it may be possible to
do this from the web via Z classes. I basically gave up and hacked the
PTK Python code directly, and I probably did it in a
not-very-nice-way, but oh well, it works. :)

I wanted my Event class to be similar to a NewsItem but with an extra
eventdate property, so that I could use dtml-calendar to create quick
links to events. So I copied NewsItem.py and began hacking. "Hacking"
in this case was basically replacing all occurences of NewsItem, news
item and News Item with Event. :) I also modified the constructor to
take an extra eventdate argument.

Then I hacked PTKBase/__init__.py. I changed a portion of it to look
like:

context.registerBaseClass(NewsItem.NewsItem, 'News Item')
context.registerBaseClass(Document.Document,'Document')
context.registerBaseClass(Link.Link, 'Link')
context.registerBaseClass(Event.Event, 'Event')

I then copied the News Item wizard, changed references from News to
Event, and added code to support inputing a date. Then I copied
newsEdit.dtml and added a similar input field, with
value="&dtml-eventdate;", which made event editting work
nicely. Finally, I hacked the Recent News pages so that the meta_data
in the Z catalog search would search for ['News Item', 'Event']
instead of just news, since they're both intended to serve identical
purposes. And that was it; I now have an Event class which serves my
purposes nicely. Hopefully I haven't broken compatibility with future
versions of the PTK; I hate modifying code locally and making my
version of something nonstandard, even if it is only slightly so.

I'm working on ZScheduler which implements basic scheduled events. It's not
related to PTK. Discussion is on zope-dev@zope.org. I just got something
functional running. If you like to play with fragile SW, check it out at

Let me know whether it fits your needs.
