Are you sure that you have Contest objects?
There is a convention in Django (models and ORM), "object.foreign_key"
gives you the object, while "object.foreign_key_id" gives you the id of
that object (and is what it is stored in the database). You should name
your field only "contest" for avoiding confusions.
