Zope - der objektorientierte Webapplikationsserver

Die Anleitung unter http://www.zopelabs.com/cookbook/1054240694 würde
wohl funktionieren, wenn ich wüsste, wie ich das defekte Objekt
herausfinden könnte. Im Traceback kann ich die Info jedenfalls nicht
finden. Gemäss Anleitung muss ich unter Punkt die url_to_obj angeben.
Ich nehme an, damit ist die URL im ZMI gemeint. Wie kann ich
herausfinden, welches Objekt welche URL hat? Der einzige Anhaltspunkt
ist 0000000000000e29, aber das ist ja keine URL.

Dies ist der Traceback:

POSKeyError: 0000000000000e29



Du benutzt die "FileStorage" Utility "fsrefs", um Deinen Storage zu überprüfen.
Sie sollte die "Dangling Reference" (das ist ein POSKeyError im Prinzip)
ermitteln mit dem Objekt, das die Dangling Reference besitzt.
"fsrefs" wird die Objekte über ihre OID identifizieren.

Du benutzt die OID für den Container, in dem das verlorene Objekt liegt,
um den Container zu laden: "container=app._p_jar[oid_as_binarystring]".
Jetzt geht es nur noch darum, die Id des kaputten Objekts zu
bestimmen:

    for i in container.__dict__.keys():
      print i; dummy = getattr(container,i).getId()

Die letzte Ausgabe vor dem POSKeyError identifiziert das
fehlende Objekt.
