我有一个像这样定义的类：
class InvestedCompany(Base):
__tablename__ = 'investedcompany'
id = Column(Integer, primary_key=True)
name = Column(String)
investor_id = column(String, ForeignKey('investments.investor_id'))
investor = relationship(
Investments,
backref=backref('investments',
uselist=True,
cascade='delete,all'))
我想进行查询并将session.query结果映射到此类。 像session.query（company.id，company.name，Investments）.filter ......
谢谢！
