Thanks! It turns out the expression is self.REQUEST.PARENTS[-1].absolute_url() I'll see if I can put this into a useful tip. -- Ira Hochman go2ira@onebox.com - email (617) 598-1014 x5511 - voicemail/fax ---- Dieter Maurer <dieter@handshake.de> wrote:

How does one retrieve the equivalent of PARENTS[-1] from within a Python Product in Zope? ZPublisher places "REQUEST" at the top of the acquisition chain. "PARENTS" is an attribute of "REQUEST".

Therefore, you should be able to simple use "self.PARENTS[-1]".

If it does not, try "self.REQUEST.PARENTS[-1]".
