You use Zope (or scripts using the Zope codebase). >the documents that we post in Plone >have id, ya? There are lots of "id"s around. The "id" used in Plone is not a universal id, but unique only locally in the container. Therefore, you cannot use it to identify and fetch an object. Modern Plone versions (2.1.x) have documents based on AT. There have a universal unique id which can be resolved via the "uid_catalog" into the object. Someone else already recommended to read the "catalog" section of the Zope Book (online 2.7 edition). Follow this advice! All persitent objects already have a "persitent id". It is not used at application level (as it is meaningless there). The persistent id is the id used by the Zope database. When you know the peristent id of an object, you can load it from ZODB *BUT* it will behave very differently from how you are acoustomed to. That's because you are *NOT* working with raw objects in Zope/Plone but with acquisition wrappers. A ZODB load gives you instead the raw object, which, among other, does not have a location, nor an URL nor a parent.... -- Dieter _______________________________________________ Zope-DB mailing list Zope-DB@zope.org http://mail.zope.org/mailman/listinfo/zope-db
