there's no reason at all that would happen, other than what's in "readings" is not what you'd expect. try iterating through every element in "readings" after the add_all(), and do "obj in session". If some of these objects were from a different session, then they may be "detached" as you put them in in which case they'd go into session.identity_map, not session.new. > > for new in session.new: > print(new, mapper.identity_key_from_instance(new_object)) > > <ThermafuserReading(thermafuserId = '1', timestamp = '2017-01-01 00:00:00')> > (<class '__main__.ThermafuserReading'>, (datetime.datetime(2017, 1, 1, 0, > 0), 1)) > > > Why is this behavior?
