Hi,
I have a problem with relationships between objects which inherit the
same parent:
class Person(DeclarativeBase):
__tablename__ = 'person'
id = Column(Integer, primary_key=True)
name = Column(Unicode(100), nullable=False
def __init__(self, name):
self.name = name
to allow proper quoting of names the schema portion of the name is separate
from the name of the table:
class AttributeConversion(Base):
__tablename__ = 'attribute_conversion'
__table_args__ = {'schema':'test'}

now that is interesting, and its a bug, and why its unusual is because you've
got a column_property() deriving from another column_property(). But the bug
is interestingly a very simple one inside the select() construct. I still
