Actually I think in this case you could probably leave the "secondary"
argument as the association table itself, but change the join
condition via the "primaryjoin" parameter. Something like this
(completely untested):
class User(Base):
id = Column(Integer, primary_key=True)
managed_teams = relationship(
'Team',
secondary=user_team_association_table,
primaryjoin=sa.and_(user_team_association_table.c.user_id == id,
user_team_association_table.c.is_manager==sa.true()),
)
