I've just committed (r1270) preliminary support for inheritance in
ActiveMapper, however, none of my tests seem to work with the Trunk
of sqlalchemy. So I need to figure out what's wrong.
In addition, there WAS some problem with multiple primary keys. For
example if you have:
class A(ActiveMapper):
class mapping:
__table__="a"
pk= column( Integer, primary_key=True )
name= column( String )
class B(A):
class mapping:
__table__="b"
pk= column( Integer, foreign_key="a.pk", primary_key=True )
age= column( Integer )
You can create an instance of B just fine, but when you attempt to
retrieve the B, I'm told I need another pk value... weird.
