Hi!
I've got this setup:
cs = "sqlite:///:memory:"
sa_engine = create_engine(cs)
Base = declarative_base()
class Person(Base):
__abstract__ = True
id = Column(Integer, primary_key=True)
name = Column(String(30))
class Employee(Person):
__tablename__ = 'employee'
manager_id = Column(Integer, ForeignKey('employee.id'))
manager = relationship('Employee', primaryjoin=(manager_id==Person.id),
remote_side=Person.id) #many-to-one
comment = Column(String(100))
Base.metadata.drop_all(sa_engine)
Base.metadata.create_all(sa_engine)
Session = sessionmaker(bind=sa_engine)
s = Session()
e1 = Employee(name='John Smith') #sqlalchemy.exc.CompileError: Cannot
compile Column object until it's 'name' is assigned.
What gives? Thanks!
