No, that's they way it is documented as working. The one-to-one field acts
as the primary key for the model, and primary keys can't be edited. From
http://www.djangoproject.com/documentation/model-api/#one-to-one-relationships
:
This OneToOneField will actually replace the primary key id field (since
one-to-one relations share the same primary key), and will be displayed as a
read-only field when you edit an object in the admin interface:
