ModelSecurity for Rails by Bruce Perens

Modelsecurity aims to provide access control within the data model so
that it becomes easy & efficient to specify read or write access to
individual fields.

It has one of those “why didn’t I think of that?” designs which make a
lot of sense.

Has anyone else tried using the latest release of ModelSecurity? What
has been your experience?
