Hmm, so I would I register different views for a KeyError versus an AttributeError? Not unless you actually need different views for them, which you probably don't. In my experience, you only need a few, as described in change notes. One additional one that isn't mentioned in the change notes but that I use a lot is UserError (zope.exceptions.UserError). This is an exception to raise when you want to display an end-user error message. Most exceptions are really application errors and should be handled by a view for Exception that displays a system error message.

[Zope-dev] Using views for exceptions in Zope 2.12?
Hi All,
Given that the source of bug #372632 appears to be code related to
allowing views on exceptions in Zope 2, I thought I'd try use this method.
I tried this, without much joy:
browser:defaultView
for=exceptions.Exception
name=error
/
browser:page
for=exceptions.Exception
template=html/error.html
name=error
permission=zope2.Public
/
So, how should I be wiring in views for exceptions?
Also, is there a base view class for exceptions anywhere that provides
the following or their equivalents?
kwargs = {'error_type': error_name,
'error_value': error_value,
'error_tb': error_tb,
'error_traceback': error_tb,
'error_message': error_message,
'error_log_url': error_log_url}
Finally, when a view is used to render and exception, is the userthe
current logged in user (as is the case with standard_error_message) or
Anonymous (as has annoyingly been the case with Unauthorized exceptions
in the past)
cheers,
Chris
