I've ran into the same issue, but solved it in a bit of a hackish =
fashion. I went the route of the schema objects knowing nothing about =
the outside world, just themselves, and their relations with other =
On top of this sits a separate set of objects that contain all the logic =
necessary to make things "work", using copious amounts of autoload =
voodoo. These objects can basically be used from any other app, be it =
Catalyst or some command line tool, and don't really have to know much =
else. For Catalyst I've got a custom model object that will return the =
appropriate "logic" object, whereas in offline tools they're used directly.
Sort of solves the problem in a cleaner way if you ask me.
