Hi everyone!

I can't solve my issue by myself, could anyone has advice on this.


I've models (simplified):
class Tournament(Base):
id = Column(UUID(as_uuid=True), primary_key=True)
owner_id = Column(UUID(as_uuid=True), ForeignKey('user.id', ondelete='
CASCADE'), nullable=False)

owner = relationship('User', back_populates='ownership', cascade='all,delete
')
players = relationship('PlayerOfTournament', back_populates='tournament', 
cascade='all,delete')

class PlayerOfTournament(Base):
__tablename__ = 'playeroftournament'

user_id = Column(UUID(as_uuid=True), ForeignKey('user.id', ondelete='CASCADE
'), primary_key=True)
tournament_id = Column(UUID(as_uuid=True), ForeignKey('tournament.id', 
ondelete='CASCADE'), primary_key=True)
user = relationship('User', back_populates='member_of', uselist=False, 
cascade='all,delete')
tournament = relationship('Tournament', back_populates='players', uselist=
False, cascade='all,delete')
rank = Column(Integer)

class User(Base):
id = Column(UUID(as_uuid=True), primary_key=True)
ownership = relationship('Tournament', back_populates='owner', cascade='
all,delete')
member_of = relationship('PlayerOfTournament', back_populates='user', cscade
='all,delete')
username = Column(String(96)) 


I would to get all tournaments, with filter by some_user not in players.
I've no idea how construct query, I tried something like 
session.query(Tournament).filter(Tournament.players.user.notin_(user.id)), 
but it doesn't work.
