this has just confused me for a while , and constantly trips me up... class FirstTable() __tablename__ = 'first_table' id = Column(Integer, primary_key=True)
class SecondTable() __tablename__ = 'second_table' id = Column(sa.Integer, primary_key=True) first_table_id = Column(sa.Integer, ForeignKey("first_table.id") ) first_table = relationship("FirstTable", primaryjoin="""FirstTable.id == SecondTable.first_table_id""") was there a specific reason why the string in `ForeignKey` is for the table+column, and not an object, like in `relationship` ? ( i know that `ForeignKey` can take an object too , i'm just wondering about the string ) -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
