In the documentation for sqlalchemy.orm.column_property, there is a section explaining the *active_history* flag. It is very terse. I think it is very useful but just cannot think of a scenario where I would ever want to use *previous* value when I'm setting a new value. Could someone use plain language to explain it a bit more? Thanks.
(I sometimes find reading SA documentations is like reading Bible, you know the content is good for you, but you cannot easily figure out how.
