Is there a saveOrUpdate hibernate equivalent in flask-sqlalchemy?

Question

Flask

Hello.
If there is no entry with a certain id, I need to write it down, if there is, update it with new data.
Is there an analogue of saveOrUpdate hibernate in flask-sqlalchemy ?

update(), save_or_update(), save() are all deprecated. add() places an object in the session in all cases, using the persistence information already associated with the object to determine INSERT or UPDATE. this means if you just make a new Foo(id=some id), that's transient - SQLAlchemy didn't load it. It will be INSERTed.
