Any feedback will be greatly appreciated. I've got schema like this:class A(Base): __table_name__ = 'a id = Column(Integer, primary_key=True)class B(Base): __table_name__ = 'b' id = Column(Integer, primary_key=True)

To post to this group, send email to sqla. The SQLA join() (and outerjoin()) construct is chained in a simlar way: tablea. You can read some more about repositories at http://markmail.org/message/aaqx4bpqmwhznewk
