[Zope] - Database difficulty

[A.M. Kuchling]

So far Principia products have only been written by experienced
developers, but with random bozos messing around with buggy
partially-implemented Products, the management code is going to have
to be made more resilient against bad objects.  Here's an example
traceback I got:

Sorry, an error occurred.

Traceback (innermost last):
  File /home/opt/zope/lib/python/ZPublisher/Publish.py, line 861, in publish_module
  File /home/opt/zope/lib/python/ZPublisher/Publish.py, line 583, in publish
    (Info: /manage_main)
  File /home/opt/zope/lib/python/Globals.py, line 222, in __call__
    (Object: manage_main)
  File /home/opt/zope/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__
    (Object: manage_main)
  File /home/opt/zope/lib/python/DocumentTemplate/DT_In.py, line 675, in renderwob
    (Object: objectItems)
  File /home/opt/zope/lib/python/OFS/SimpleItem.py, line 144, in title_and_id
    (Object: Item)
AttributeError: id

	The problem in this case arose from a syntax error in the
code for the product, which made the module import fail.  When I
changed title_and_id(self) to:
        t=self.title
        try:
            i=self.id
        except AttributeError:
            i="No ID!" + repr(self)
        return t and ("%s (%s)" % (t,i)) or i

Zope correctly displayed that this object was broken.  I'm not sure if
this suggested change is the right one, but it worked for me...

You have called me here, Haroun. It is unwise to summon what you cannot
dismiss.
