python - SQLAlchemy ForeignKey找不到表

当我尝试实例化ConsumerAdvice类时出现此错误。

Foreign key associated with column 'tbConsumerAdvice.ConsumerAdviceCategory_ID'
could not find table 'tbConsumerAdviceCategories' with which to generate a
foreign key to target column 'ID_ConsumerAdviceCategories'

class ConsumerAdviceCategory(Base):
    __tablename__ = 'tbConsumerAdviceCategories'
    __table_args__ = {'schema':'dbo'}
    ID_ConsumerAdviceCategories = Column(INTEGER, Sequence('idcac'),\
            primary_key=True)
    Name = Column(VARCHAR(50), nullable=False)

    def __init__(self,Name):
        self.Name = Name

    def __repr__(self):
        return "< ConsumerAdviceCategory ('%s') >" % self.Name

class ConsumerAdvice(Base):
    __tablename__ = 'tbConsumerAdvice'
    __table_args__ = {'schema':'dbo'}
    ID_ConsumerAdvice = Column(INTEGER, Sequence('idconsumeradvice'),\
            primary_key=True)
    ConsumerAdviceCategory_ID = Column(INTEGER,\
            ForeignKey('tbConsumerAdviceCategories.ID_ConsumerAdviceCategories'))
    Name = Column(VARCHAR(50), nullable=False)
    Category_SubID = Column(INTEGER)

    ConsumerAdviceCategory = relationship("ConsumerAdviceCategory",\
            backref=backref('ConsumerAdvices'))

    def __init__(self,Name):
        self.Name = Name

    def __repr__(self):
        return "< ConsumerAdvice ('%s') >" % self.Name

最佳答案

定义包括架构的FK:dbo.tbConsumerAdviceCategories.ID_ConsumerAdviceCategories
