django-sitemaps

sitemap.xml generation using lxml with support for alternates. It uses Python 3's keyword-only arguments for self-documenting code.

Installation

Simply pip install django-sitemaps. The package consists of a single python module, django_sitemaps, containing the single class; there's no additional configuration necessary.

Usage

View:

from app.pages.sitemaps import PagesSitemap

def sitemap(request):
    sitemap = Sitemap(
        # All URLs are passed through build_absolute_uri.
        build_absolute_uri=request.build_absolute_uri,
    )

    # URLs can be added one-by-one. The only required argument
    # is the URL. All other arguments are keyword-only arguments.
    for p in Page.objects.active():
        url = p.get_absolute_url()
        sitemap.add(
            url,
            changefreq='weekly',
            priority=0.5,
            lastmod=p.modification_date,
            alternates={
                code: urljoin(domain, url)
                for code, domain in PAGE_DOMAINS[p.language].items()
            },
        )

    # Adding conventional Django sitemaps is supported. The
    # request argument is necessary because Django's sitemaps
    # depend on django.contrib.sites, resp. RequestSite.
    sitemap.add_django_sitemap(PagesSitemap, request=request)

    # You can also specify the site and protocol manually should you wish
    # to do so:
    sitemap.add_django_sitemap(
        PagesSitemap, site=...site..., protocol=request.scheme
    )
    # Note! If you're omitting the request you *have* to specify site and
    # protocol yourself.

    # You could get the serialized XML...
    # ... = sitemap.serialize([pretty_print=False])
    # ... or use the ``response`` helper to return a
    # ready-made ``HttpResponse``:
    return sitemap.response(
        # pretty_print is False by default
        pretty_print=settings.DEBUG,
    )

URLconf:

from django_sitemaps import robots_txt
from app.views import sitemap

urlpatterns = [
    url(r'^sitemap\.xml$', sitemap),
    url(r'^robots\.txt$', robots_txt(timeout=86400)),
    ...
]

The robots_txt function returns a view which can be used to generate a robots.txt file containing sitemap URLs. The default sitemap only contains:

User-agent: *
Sitemap: <protocol>://<host>/sitemap.xml

The list of sitemap URLs may be overridden by setting sitemaps:

from django.urls import reverse_lazy

urlpatterns = [
    url(r'^robots\.txt$', robots_txt(
        timeout=86400,
        sitemaps=[
            '/sitemap.xml',
            reverse_lazy('articles-sitemap'),
            ...,
        ],
    )),
]
