assign_mapper on TurboGears. It's using SessionContext.

Where does engine come from?
I can't follow much with all those asterisks.
Try "import sqlalchemy as sa", it saves enough typing.
As a rule, I like to be able to say where objects come from, it helps
immensely.
In this case, engine is the module sqlalchemy.engine
BTW: what are you doing with widgets and validators in your model? Are
you sure that usage does not belong to controllers or somewhere else
entirely?

Sorry, I should have been more explicit:
from turbogears import database
engine = database.get_engine()
