Django TypeError bei /sitemap.xml Sequenzindex muss Integer sein, nicht 'Scheibe'

Question

Ich habe seltsames Problem mit meiner Sitemap-Seite.

# -*- coding: utf-8 -*- 
from __future__ import unicode_literals 

import datetime 
import urllib 

from django.core.urlresolvers import reverse 
from django.contrib.sitemaps import Sitemap 
from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger 
from pytz import UTC 

from mychat.models import Question 

MONTHLY = 'monthly' 
WEEKLY = 'weekly' 
DAILY = 'daily' 
HOURLY = 'hourly' 
now = datetime.datetime.utcnow().replace(tzinfo=UTC) 

# The following lists are separated only for fixed ordering. 


class RecentForumViewPaginationSitemap(Sitemap): 
    """ 
    Sitemap generator that takes Django Recent tab in forum list view and 
    generates all pages in pagination. 
    """ 
    changefreq = DAILY 
    priority = 0.90 
    protocol = 'https' 

    def items(self): 
     post_queryset = Question.objects.all().order_by('-created') 
     paginator = Paginator(post_queryset, 12) 
     return paginator.page_range 

    def location(self, page): 
     return '?'.join([reverse('question_list'), urllib.urlencode({'recent_page': page})]) 

sitemaps = { 
    'recent_forum_views': RecentForumViewPaginationSitemap, 
} 

Es appread nach den jüngsten Upgrade auf Django 1.9.7

urls.py

# -*- coding: utf-8 -*- 
from __future__ import unicode_literals 

from django.conf.urls import patterns, url 

from my.sitemap import sitemaps 

urlpatterns = patterns(
    '', 
    url(r'^sitemap\.xml$', 'django.contrib.sitemaps.views.sitemap', {'sitemaps': sitemaps, 
                    'template_name': 'my/custom_sitemap.xml'}), 
) 

custom_sitemap.xml

<?xml version="1.0" encoding="UTF-8"?> 
<urlset 
     xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 
      http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd"> 
{% spaceless %} 
{% for url in urlset %} 
<url> 
<loc>{{ url.location }}</loc> 
{% if url.lastmod %}<lastmod>{{ url.lastmod|date:"Y-m-d" }}</lastmod>{% endif %} 
{% if url.changefreq %}<changefreq>{{ url.changefreq }}</changefreq>{% endif %} 
{% if url.priority %}<priority>{{ url.priority }}</priority>{% endif %} 
</url> 
{% endfor %} 
{% endspaceless %} 
</urlset> 

Ich erhalte Zurückverfolgungs:

TypeError: sequence index must be integer, not 'slice' 

Ich frage mich, ob jemand in letzter Zeit auf ein ähnliches Problem gestoßen ist oder mich in die richtige Richtung lenken kann, um es zu lösen. Danke für jeden Hinweis.

Answer 1

ich das denke, ist Ihre rückwärts inkompatible Änderung:

• Make paginator.page_range an iterator

Um dies zu beheben, die Liste aus der items() Methode zurück:

def items(self): 
    post_queryset = Question.objects.all().order_by('-created') 
    paginator = Paginator(post_queryset, 12) 
    return list(paginator.page_range) 

Hinweis: Ich bin weit davon von einem Experten in Django und dem Sitemap-Framework - es könnte einen besseren Weg geben, dies zu lösen. Ich hoffe, das wäre zumindest ein Schritt in die richtige Richtung.
