this is self explanatory, but error is below
i'm using sqlalchemy to reflect a table. it reads it fine.
when i try to assign a mapper, i get "has no attribute '_class_state'"
looking at orm.mapper.py
734:
if self.non_primary:
self._class_state = self.class_._class_state
_mapper_registry[self] = True
return
if i look at the dict around 735, self.class_._class_state not set
i couldn't find where self.class_._class_state was set elsewhere in
the code
is this a bug? could something else be at fault?
