There are a lot of ways to handle versioning in SqlAlchemy. This is just one example. The docs show another approach as well (http://docs.sqlalchemy.org/en/latest/orm/examples.html#versioning-objects)
It's not included, because it's just an example. It won't suit all cases and many people will want to adapt. Unlike most other db packages, SqlAlchemy is not opinionated and doesn't force an approach. One of my projects has 3 types of versioning, depending on the content type and business needs. If you want a full-fledged versioning system, there are a few plugins and projects on PyPi. One I recall offhand is "sqlalchemy-continuum" -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
