Is there a way to find out if a persistent sqlalchemy mapped object was modified? It means I recieve a object (persistent, with identiy) from the database. Then the user (maybe!) modify its data in a dialog-window. obj = session.query(MyClass).first() LetTheUserDoSomethingWithIt(obj) if obj.is_modified() Is there a way to find out if the object in memory/RAM was modified compared to its instance in the database itself? I don't want to compare each attribute against the data in the dialog-window.
session.is_modified(obj) will do this for you: http://docs.sqlalchemy.org/en/rel_1_0/orm/session_api.html?highlight=is_modified#sqlalchemy.orm.session.Session.is_modified read the docs carefully, this method can be tricky.
