[Zope] Add a folder anywhere from anywhere

[Francois-Regis CHALAOUX]

Hi,

USE CASE
========
How to test if an "idFolder" exist in my "topFolder"?
If the "idFolder" does not exist I would like to add it to "topFolder"

Question
======
Who know why this code in an external method (EM) does not work?

Code
====
def addFolder(self, idFolder, topFolder):
   self=self.this()
   if not hasattr(topfolder,idFolder):
      self.getattr(self,topFolder).manage_addFolder(idFolder)


PS: How to add a folder anywhere in the ZODB tree with an EM also located
anywhere?

Bye, FR.
