   Bases: :py:obj:`django.db.models.OneToOneField`

   A OneToOneField is essentially the same as a ForeignKey, with the exception
   that it always carries a "unique" constraint with it and the reverse
   relation always returns the object pointed to (since there will only ever
   be one), rather than returning a list.

   .. py:method:: contribute_to_class(cls, name)

      Register the field with the model class it belongs to.

      If private_only is True, create a separate instance of this field
      for every subclass of cls, even if cls is not an abstract model.
