Question

我的网站地图页面存在奇怪的问题。

# -*- 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,
}

最近升级到Django 1.9.7之后它才会被推荐

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类似的问题，或者能指出我正确的方向来解决它。谢谢你的任何建议。

Answer 1

我认为这是你向后兼容的变化：

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：我远不是Django和Sitemap框架的专家 - 可能有更好的方法来解决这个问题。我希望这至少会成为迈向正确方向的一步。

/sitemap.xml序列索引处的Django TypeError必须是整数，而不是＆＃39; slice＆＃39;
