Hello Everyone,
First of all, kudos on SQLAlchemy.. the speed is pretty amazing - I
am coming from the SQLObject world and there is a definite difference.
Excellent work. I am also getting to grips with it pretty quickly,
using object_session and all that good stuff. This said, I have hit
that 20% problem, and am hoping someone can shine a light on it.
I have a table, lets call it Foo and another table Bar. Foo should
be able to get a list of it's parents via Bar or it's children via
Bar. I am also using the declarative_base system rather than table/
mapper defined seperately.
class Foo(Base):
id = Column(Integer, primary_key=True)
class Bar(Base):
parent_id = Column(Integer, default=0)
child_id = Column(Integer, default=0)
So, I thought something like ; children = relation(Foo,
backref=backref('parents'), primaryjoin=and_(Foo.id==Bar.parent_id)
But that's where I hit the 'wall' as it were, is there a way to
setup a synonym for Foo in the primaryjoin clause ? Am I missing
something stupid ? (I am okay with that ;)
Regards
Stef
