You can use Steve Alexander's ZedPatterns/TransactionAgents:

Can you elaborate on this.  It sounds like some of the ideas you have
can definitely be useful as extensions to ZPatterns especially the
generation of a ZMI for a class. I think auto-generation of formulator
forms for the management of a class will be really cool.

The howto is still a work in progress and is turning out to be quite a
big job. Although I indicated that I wanted to release my extensions and
the howto this weekend I'm putting this off for another week. I hope to
make some real progress this weekend. Hope you can wait a while.
