DoesNotExist at /admin/blog/blog/add/: blog matching query does not exist
Suddenly I can no longer add blogs to Django. Django says 'blog matching query does not exist'. That seems strange to me because I want to add something to the database and not request a blog. What could be going on here? admin.py: class blogadmin(admin.ModelAdmin): def save_model(self, request, obj, form, change): if not change: obj.added_by_user = request.user.username obj.ip_added = request.META['REMOTE_ADDR'] if obj.ip_added == '127.0.0.1': obj.ip_added = request.META['HTTP_X_FORWARDED_FOR'] obj.publish = False del obj.publish_date else: obj.changed_by_user = request.user.username obj.ip_changed = request.META['REMOTE_ADDR'] if obj.ip_changed == '127.0.0.1': obj.ip_changed = request.META['HTTP_X_FORWARDED_FOR'] if obj.publish == True: if not obj.publish_date: obj.publish_date = obj.datetime_changed super(blogadmin,self).save_model(request, obj, form, change) I can add text, photographs etc., but no blogs.
