Here is the solution I found, took way too long to understand this...
class Team(Base):
__tablename__ = "teams"
id = Column(Integer, primary_key=True)
name = Column(String)
espn_team_id = Column(Integer, unique=True, nullable=False)
h_games = relationship(
"Game",
primaryjoin="Game.h_espn_id==Team.espn_team_id",
order_by="Game.date")
a_games = relationship(
"Game",
primaryjoin="Game.a_espn_id==Team.espn_team_id",
order_by="Game.date")
@hybrid_property
def games(self):
return self.h_games+self.a_games
def __init__(self, name):
self.name = name
self.espn_team_id = espn_team_id
self.h_games = h_games
self.a_games = a_games
self.games = games
