Hello.
I'm following along with djangobook.com and trying to make necessary
changes to port django to version 1.0. In Django's Site
Administration, chapter 6, I run into the error:
Exception Type: AlreadyRegistered
Exception Value: The model Book is already registered
Exception Location: /usr/local/lib64/python2.5/site-packages/django/
contrib/admin/sites.py in register, line 64
I used the site administration site successfully with just "Book", and
then when I attempted to add the other models (Auther, Publisher), I
received the above error.
in admin.py I have:
from django.contrib import admin
from models import Book, Author, Publisher
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)
When I updated admin.py I ran:
python manage.py syncdb
It is as if the database wasn't "synced" though, and that two
instances of this model are trying to be created.
When I searched around for this error, I found instances of this
occuring in 0.96, with the model being called several times. The Admin
changes in 1.0 were said to resolve this, so perhaps it is something
else.
I appreciate any help. Thanks!
