[Sqlalchemy-tickets] Issue #3637: Add to SQLAlchemy Session in before_flush event? (zzzeek/sqlalchemy)

New issue 3637: Add to SQLAlchemy Session in before_flush event?
https://bitbucket.org/zzzeek/sqlalchemy/issues/3637/add-to-sqlalchemy-session-in-before_flush

Roman D.:

Is there a proper way to add new object to Session while in before_flush event without infinite loop?

Example:


```
#!python

from sqlalchemy import event

@event.listens_for(SomeSessionOrFactory, 'before_flush')
def receive_before_flush(session, flush_context, instances):
    session.add(NEW_OBJECT)
```

I'm trying to make logging system for all models. Maybe there is a better way to do this? :)
