Execution of arbitrary code on database update

Has IC any infrastructure to execute arbitrary code on a
database update. I'm writing an administration frontend
for a mail server with IC's UI and I need some way to
create maildirs for new accounts etc.

My guess is "no". It seems to me that IC only executes code when
pages load. So, you would need to do whatever processing on the page
that actually does the update. If you have more than one page that
does the update, consider a user-tag or a catalog scoped subroutine
(like bar_link).

If it is not there, I would consider to hack it in. Maybe
Akopia can comment on an possible interface.

Stefan,

It sounds like you are interested in basically a database-independent
trigger capability for Interchang, something like you get with Oracle and
PostgreSQL, right? So you could define a certain database state (new row
inserted, row deleted, etc.) and have certain code execute?

Sth. like that, yes. I assume that would be useful anyway.
