Hi,
Why undermentioned code will not work with SA 0.2.6 anymore?
sqlalchemy.exceptions.ArgumentError: Class '<class '__main__.Bar'>' already has a primary mapper defined. Use is_primary=True to assign a new primary mapper to the class, or use non_primary=True to create a non primary Mapper
So, creating two instances of Foo tries to assign a mapper to Bar twice since the mapper assignment is in Foo's constructor.
