Every Zope object has it's own unique id ( _p_oid ).

To convert it into integer value:

from Shared.DC.xml.ppml import u64 as decodeObjectId
oid = decodeObjectId(getattr(<Object instance>, '_p_oid'))

Is it possible to get object itself having it's _p_oid?

I tried this:

from ZODB.utils import p64
object = <RootObject instance>._p_jar[p64(oid)]

But it seems it's a wrong way
