[Zope-CMF] Query portal_catalog for current object?

[seb bacon]

Can the values be computed attributes of the content type itself (for
example, pythonscript methods on the ZClass)?  That's the best way of
doing it - then you just add the name of that attribute to the catalog
index for it to be catalogued.

Otherwise, to answer your question, you'd have to get a record from the
catalog like 

  item_brain = portal_catalog(id=this_id)

Then if the property you're after is part of the metadata for the index
you can just go

  item_brain.property

Or if it's not, you can get the object itself like:

  ob = item_brain.getObject()
