during testing, I found out that this code works, but I'm wondering if it
should...
# this returns a tuple `(464061L,)`
max_id__snapshot =
dbSession.query(sqlalchemy.func.max(models.Snapshot.id)).first()
print type(max_id__snapshot)
<class 'sqlalchemy.util._collections.KeyedTuple'>
# this submits the tuple to psycopg2 `(464061L,)` ; an INT is inserted
trackedData.max_id__snapshot = max_id__snapshot
print type(trackedData.max_id__snapshot)
<class 'sqlalchemy.util._collections.KeyedTuple'>
dbSession.commit()
print type(trackedData.max_id__snapshot)
<type 'int'>
it's still a KeyedTuple on a `flush()`. looking at the debug logs,
psycopg2 is getting the tuple and inserting as an INT. the post-commit
`type` is via the select value.
does anyone know if this "should" work?
looking at the dbapi and psycopg2 docs, there's nothing to suggest this
should work.
