# We intentionally register Promo and ChapterXtra1 but not Chapter nor ChapterXtra2.

#     related ForeignKey object registered in admin
#     related ForeignKey object not registered in admin
#     related OneToOne object registered in admin
#     related OneToOne object not registered in admin
# when deleting Book so as exercise all four troublesome (w.r.t escaping
# and calling force_text to avoid problems on Python 2.3) paths through
# contrib.admin.utils's get_deleted_objects function.
