NoMethodError 'user' in Rails console

Here is my console output, its just calling my news object and using it in the command line, i just don't understand why there is a method error when there is clearly a user model. 

 2.0.0-p353 :021 > News
     => News(id: integer, description: string, created_at: datetime, updated_at: datetime) 
    2.0.0-p353 :022 > @news = News.first
      News Load (0.3ms)  SELECT "news".* FROM "news" ORDER BY "news"."id" ASC LIMIT 1
     => #<News id: 4, description: "hello", created_at: "2014-03-08 23:08:53", updated_at: "2014-03-08 23:08:53"> 
    2.0.0-p353 :023 > @news
     => #<News id: 4, description: "hello", created_at: "2014-03-08 23:08:53", updated_at: "2014-03-08 23:08:53"> 
    2.0.0-p353 :024 > @news.user
    NoMethodError: undefined method `user' for #<News:0x00000101cee080>

Your News model has to have an association field for the user (usually called 'user_id'). That's how it knows which user it belongs to. You can do this with a migration.
