Django类型错误/网站地图.xml序列索引必须是整数，而不是“切片”

Question

我的网站地图页面有个奇怪的问题。在

# -*- 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,
}

在最近升级到django1.9.7之后，它才开始运行

在网址.py在

定制_网站地图.xml在

<?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>

我得到了回溯：

    return self._get_page(self.object_list[bottom:top], number, self)
TypeError: sequence index must be integer, not 'slice'

我想知道最近是否有人遇到过类似的问题，或者能给我指出解决问题的正确方向。谢谢你的建议。在

我认为这是你向后不相容的改变：

• Make paginator.page_range an iterator

要解决此问题，请从items()方法返回列表：

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

注意：我还远不是Django和Sitemap框架的专家-有更好的方法来解决这个问题。我希望这至少是朝着正确方向迈出的一步。在
