[Zope] Newbie: Python:Path Troubles

[Rebecca.R.Hepper@seagate.com]

Thanks much for the reply.

When I try to use restrictedTraverse or unrestrictedTraverse in my python
script I always get the error:

Error Type:  NameError
Error Value:  global name 'restrictedTraverse' is not defined

I did spell it correctly and mine looks like the examples I find on the
net.  What does this error mean?

What is the "path name"? Do you mean the "URL"?

This is exactly, how "path" should work:

     It turns a path into an object, in this case into a "PortalFolder"
     object.

     As the generated HTML can only contain strings, ZPT calls
     the "str" method on the object. This results in
     "<PortalFolderI instance at ...>".

What you need to do:

     Pass the path string itself as value of the hidden variable.
     Use "restrictedTraverse" in you Python Script to resolve it
     into an object.
     Call "setDescription" on this object.
