在/sitemap.xml序列索引处的Django TypeError必须是整数，而不是'切片'

Question

我的网站地图页有奇怪的问题。

# -*- 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, 
} 

它最近升级后appread到Django的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> 

我正在追踪：

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

我不知道最近是否有人遇到类似的问题，或者可以指出我正确的方向来解决它。感谢您的任何建议。

Answer 1

我觉得这是你的向后兼容的变化：

• Make paginator.page_range an iterator

要解决此从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：我很远从成为Django专家和Sitemap框架 - 可能有更好的方法来解决这个问题。我希望这至少能够朝着正确的方向迈出一步。
