Thanks for the replies. I restarted the dev server (and even my x
session).
I first tried:
class BookAdmin(admin.ModelAdmin):
pass
#admin.site.register(Book, BookAdmin)
class AuthorAdmin(admin.ModelAuthor):
pass
#admin.site.register(Author, AuthorAdmin)
class PublisherAdmin(admin.ModelPublisher):
pass
#admin.site.register(Publisher, PublisherAdmin)
And received the following error:
AttributeError: 'module' object has no attribute 'ModelAuthor'
I then tried the second suggestion:
#class BookAdmin(admin.ModelAdmin):
# pass
admin.site.register(Book, BookAdmin)
#class AuthorAdmin(admin.ModelAuthor):
# pass
admin.site.register(Author, AuthorAdmin)
#class PublisherAdmin(admin.ModelPublisher):
# pass
admin.site.register(Publisher, PublisherAdmin)
And receive the error:
File "$HOME/djcode/mysite/books/admin.py", line 6, in <module>
admin.site.register(Book, BookAdmin)
NameError: name 'BookAdmin' is not defined
Any other thoughts?
