Sitemaps are how web crawlers such as search engines find your pages! Rather than having to grab your links and parse your html, they’re all already there.

    "wagtail.contrib.sitemaps",

now to the core urls.py!!!

We are going to want to make some routable pages exist in this sitemap!

In our blog models:

def get_context(self, request, *args, **kwargs):
        """Adding Custom stuff to our context."""
        context = super().get_context(request, *args, **kwargs)
        context["posts"] = BlogDetailPage.objects.live().public()
      return context

@route(r'^latest/?$', name="latest_posts")
def latest_blog_posts(self, request, *args, **kwargs):
    context = self.get_context(request, *args, **kwargs)
    context["latest_posts"] = BlogDetailPage.objects.live().public()[:1]
    return render(request, 'blog/latest_posts.html', context)

def get_sitemap_urls(self, request):
    # uncomment to havae no sitemap for this page
    # return []

    sitemap = super().get_sitemap_urls(request)
    sitemap.append(
        {
            "location": self.full_url + self.reverse_subpage("latest_posts"),
            "lastmod": (self.last_published_at or self.latest_revision_created_at),
            "priority": 0.9
        }
    )
    return sitemap

If you want the routed page to not enter the xml, just return the function with an empty list!
