This suggests to me that this object has some kind of unique ID 02620E00 that identifies this particular instance.

Is there any way that I can query an object to find this id? My aim is to find some way to uniquely identify all objects so that I can find them later without having to store their entire path.

I asked for this on the zope mailing list a few months ago, and while it's true there is a unique ID for each zope object, it seems to change each time you move the object (and probably in other situations) . I'd recommend to generate your own ID as a property of the object (you could monkeypatch some base class) and use this instead of the uid provided by zope. This is imho something that should be included in the zope core, but a well made monkeypatch can solve the problem in the short term. hth Philippe

<xy at zz> is pythons way to str objects, which do not have a str repr. Also, (at least for persistent objects), this will change each time some instance attribute changes, "zz" being a location in ZODB. ------------------------------------------------------------- Who's got only a hammer sees the world as a nail hans augustin (software developer) hans@beehive.de beehive elektronische medien GmbH http://www.beehive.de phone: +49 30 847-82 0 fax: +49 30 847-82 299
