Unless you need to use all the readings immediately, have you considered
just making a custom def under the Sensor model, and then inserting all the
readings via sqlalchemy core? That would allow you to insert them without
creating ORM objects, which people using numpy and a lot of data often like
to avoid.
Then you could do...
s = Sensor()
session.add(s)
session.add_readings(dates, voltages, values)
it would look something like this...
class Sensor(Base):
def add_readings(self, dates, voltages, values):
if not self.id:
# flush this to the session
session = object_session(self)
session.flush(objects=[self])
# insert via core
