Hi,
I'm trying to create a mapped class that allows parent/child
relation of itself. I've spent the last 3 hours searching and reading
the other posts on this, but can't get anything to work.
I'm on 0.5rc4 and just want to declare this in a mapped class as such:
class Conversion(Base):
__tablename__ = 'conversion'
id = Column(Integer, primary_key=True)
name = Column(String(20))
parent_id = Column(Integer, ForeignKey('conversion.id'))
parent = relation("Conversion", backref="child")
children = relation('Conversion', secondary=conversion_conversion,
backref='parents')
I was hoping to use the same style many-to-many declarations I do
elsewhere. It creates fine, but doesn't work when adding objects.
The other posts and examples I saw do not use the class Conversion
(Base): style of automapping, which I'd like to maintain.
Anyone have good tips for this?
Darren
PS. I've seen the documentation links and base_tree.py, but I don't
want to mix mapping styles If possible.
