is there a feature or pattern for adding a listener that is to be executed

this is more of a code architecture and design question but I'm wondering
what the best practices are regarding declarative models. On the one

Hi,
I found an older thread about using a bindparam with required=True
(http://groups.google.com/group/sqlalchemy/tree/browse_frm/thread/
cc0cafb0241c51da/a5fdd0aeefecd75c) but the example doesn't work for me
on 0.7.4, it still passes None instead of raising an exception. Am I
missing something
Thanks, didn't know that, though in this case I want the keys in the
same column order but keys() doesn't preserve it.
