Wagtail 2.4 - get_sitemap_urls() 需要 1 个位置参数，但给出了 2 个

Question

在升级到 Wagtail 2.4 之前，我曾经有一个可用的站点地图。我已经根据此处的文档升级了我的网站：http://docs.wagtail.io/en/v2.4/reference/contrib/sitemaps.html但仍然没有这样的运气。我收到的错误是

get_sitemap_urls() takes 1 positional argument but 2 were given

。

我已将

'django.contrib.sitemaps',

添加到我的基本设置中的

INSTALLED_APPS

，并将以下内容添加到我的

urls.py

：

from wagtail.contrib.sitemaps.views import sitemap

urlpatterns = [
    ...

    url('^sitemap\.xml$', sitemap),

    ...
]

我的页面模型包含以下内容：

def get_sitemap_urls(self, request=None):
        return [
            {
                'location': self.get_full_url(request),
                'lastmod': (self.last_published_at or self.latest_revision_created_at),
                'changefreq': 'monthly',
                'priority': .5,
            }
        ]

我之前包含了一个 sitemap.xml 文件来覆盖旧的

wagtailsitemaps/sitemap.xml

，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
{% 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>

追溯：

知道我错过了什么吗？我已经完成了文档中所说的所有操作，而且非常基本。除了这些步骤之外，我在网上找不到任何其他内容。

Answer 1

试试这个：

def get_sitemap_urls(self, obj):
    return obj.last_published_at

Answer 2

在从站点地图中删除特定页面模型时遇到问题并遇到帖子标题中提到的相同错误时遇到了这篇文章。这在 Wagtail 5.2.3 中对我有用：

def get_sitemap_urls(self, *args):
    return []

或者只是：

 def get_sitemap_urls(*args):
        return []
