No, I think you're seeing the same behaviour for all fields - ie you're
retrieving the value of the key for the related item. However for the Status
model, that value is a string since you've defined a charfield as the
primary key.
Under the hood, related fields store the key of the related item, not the
item itself. Clever Stuff (TM) in the ORM then reifies those objects as
needed.
