def __init__( me, **ka):
for k,v in ka.iteritems(): setattr( me,k,v)
def update( me, ka):
for k,v in ka.iteritems(): setattr( me,k,v)
generic repr/str is more tricky... one way is like:
for p in object_mapper(self).iterate_properties:
print getattr( self, p.key)
or was it something similar...
be careful with recursive a-b-a or a-a relations... if u want a sort-of fool
proof generic str, see here:
