    877877models can be made by using a string containing the model name.
    878878
    879879This ``OneToOneField`` will actually replace the primary key ``id`` field
    880 (since one-to-one relations share the same primary key), and has a few
    881 differences in the admin interface:
     880(since one-to-one relations share the same primary key), and will be displayed
     881as a read-only field when you edit an object in the admin interface:
    882882
    883     * No ``Place`` selection interface is displayed on ``Restaurant`` pages.
    884       There will be one (and only one) ``Restaurant`` for each ``Place``.
    885 
    886     * On the ``Restaurant`` change list, every ``Place`` -- whether it has an
    887       associated ``Restaurant`` or not -- will be displayed. Adding a
    888       ``Restaurant`` to a ``Place`` just means filling out the required
    889       ``Restaurant`` fields.
