I found many posts about get_transaction().rollback() but it is 
deprecated in Zope 2.9. What is the modern way of doing this?


I'd use a custom error_page and just raise the exception.

2006-06-20 Thread Chris McDonough 

import transaction
transaction.abort()

should do it.  I will spare you the nannylike warnings about managing  
your own transaction state..
