[Zope-dev] Confused about catalog unique ID in ZScheduler

[Loren Stafford]

Two questions really:

1. How do I get the uid from the catalog in a python product. Currently I
have

    for event in self._catalog.searchResults(
            nextEventTime=DateTime(1),
            nextEventTime_usage='range:min',
            sort_on='nextEventTime'
            ):
      next_url = event.absolute_url
      next_time = event.nextEventTime
      #next_uid = event.uid
      break  # just look at the first one
    return (next_uid, next_time, next_url)

...but that event.uid line isn't correct.

2. I need to add to ZScheduler the ability to delete a catalog entry if the
Dispatcher gets an error when it tries to disarm an event. Is uid what I
need in ZScheduler to subsequently do this?

      self.uncatalog_object(uid)

My confusion here is knowing that uid is based on relative URL but knowing
(vaguely) that relative URL is problematic in vurtual hosting environment
(the very reason that ZScheduler catalogs absolute_url and uses it to
identify the target ZEvent). Can someone clarify?
