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. -- SQLAlchemy - The Python SQL Toolkit and Object Relational Mapper http://www.sqlalchemy.org/ To post example code, please provide an MCVE: Minimal, Complete, and Verifiable Example.
