The BrainFreeze project is an SQLAlchemy plugin that supports object composition (as opposed to class inheritance). Google for "composition vs inheritance" to get the general idea. Another way to think of BrainFreeze is that it's a plugin for proxying properties on one-to-one related objects. Kind of like SQLAlchemy's AssociationProxy, but for one-to-one relations instead of many-to-many relations.
OneToOneProxy
BrainFreeze provides an SQLAlchemy Python Property that will take all the foreign columns in a one-to-one relation and make them accessible on the mapped class. Kind of like SQLAlchemy's AssociationProxy but for one-to-one relations.
But wait! There's More! Also included is a SQLAlchemy MapperProperty that lets these foreign columns be query-able just as if they were normal columns on the mapped class.
Act now and you'll receive as our special gift to you, an SQLAlchemy MapperExtension that sets this all up for you automatically.
