I've successfully installed Django-SEO, but when I try to limit the number of backends (I only need/want my admin to have 'path' and not the other three) I am met with the following error:AttributeError at /admin/
'NoneType' object has no attribute '_meta'
seo.py
from rollyourown import seo
class AppMetadata(seo.Metadata):
title = seo.Tag(head=True, max_length=68)
description = seo.MetaTag(max_length=155)
class Meta:
backends = ('path',)
#backends = ('path', 'modelinstance', 'model', 'view',) This works but includes all default backends
admin.py
from django.contrib import admin
from rollyourown.seo.admin import register_seo_admin
from localsite.seo import AppMetadata
register_seo_admin(admin.site, AppMetadata)
