oh that should be mapper(TrafficInput, sel, non_primary=True)

you'd need to make a relationship() that explicitly joins out among all four
tables so that the .Time column is available. To accomplish that you'd
probably want to make a non primary mapper to join to, it would look something
like this:
sel = select([TrafficInput,
Traffic.Time]).sele
Given the following classes/tables:
class TagList(Base):
TagID = Column(Integer, primary_key=True)
trafficInputs = relationship('TrafficInput', secondary='TagCaseLink',
order_by='Traffic.Time')
class TagCaseLink(Base):
TagID = Column(Integer, ForeignKey('TagList.TagID'), primary_key=T
