body: <p>Using Djangorestframework I had created rest api. I have two models in my app countries and states. I had related countries model to states model using Foreign key method, But while fetching list of states in States api i am getting states names, but in the place of country i am getting countries primary key id instead of it's name how can i get all the fields of Countries instead of PK id</p>

  class states(models.Model):
      state = models.CharField(max_length=15)
