Django Sitemap Extras is a rethink of the builtin django.contrib.sitemaps module which focuses on better performance, more flexibliity and support for a larger variety of formats. Just like the contrib sitemaps app, Sitemap extras suports the regular sitemaps.org protocol of Sitemaps and Sitemap Indexes. In addition, the app also supports the Google Sitemap formats including video, images, mobile, and news.
Use pip for installation. This package requires the lxml library which means you will need a C compiler. This package relies heavily on class based views so if you have Django<=1.2 installed, you will need the django-cbv package.
pip install git+https://github.com/justquick/django-sitemap-extras.git#egg=django-sitemap-extras
You may add sitemapext to your INSTALLED_APPS if you wish to test it within your project, but it is not necessary otherwise.
Django Sitemap Extras has been tested with all of the following setups
| Django: | 1.2, 1.3, 1.4, 1.5, 1.6 |
|---|---|
| Python: | 2.6, 2.7, 3.2, 3.3, PyPy |
All Sitemaps are based on class based views so you can override the model/queryset/get_queryset attributes in order to generate the items to represent in a Sitemap. Querysets are paginated by 50,000 items by default to match the Sitemap protocol specs but you can override any pagination settings just like any other ListView class. Just like the contrib sitemaps app, you can specify the sitemap specific attributes (eg lastmod, changefreq) on the Sitemap subclass using functions that take an object and return the Sitemap information. For the following usage examples we will use the simple model below as an example
class MyModel(models.Model):
name = models.TextField()
update_date = models.DateTimeField()
pub_date = models.DateTimeField()
is_mobile = models.BooleanField(default=False)from sitemapext import SitemapView
class MySitemapView(SitemapView):
model = MyModel
def priority(self, obj):
return .5 # Float from 0.0 to 1.0
def lastmod(self, obj):
return obj.update_date.date() # Date or datetime instance
def changefreq(self, obj):
return 'daily' # One of the change frequencies from the Sitemap specTo activate sitemap generation on your Django site, add these lines to your URLconf:
from sitemapext import SitemapIndex, SitemapGenerator
sitemaps = {
'simple': ModelSitemapView,
}
urlpatterns = patterns('',
url(r'^sitemap-index\.xml$', SitemapIndex.as_view(),
{'sitemaps': sitemaps, 'generator': 'sitemap-generator'}),
url(r'^sitemap-(?P<section>.+)\.xml$', SitemapGenerator.as_view(),
{'sitemaps': sitemaps}, name='sitemap-generator'),
)The SitemapIndex view takes a 'generator' kwarg which is the name of the URL for the SitemapGenerator view. The SitemapGenerator view takes a 'section' kwarg which corresponds to the section key of the sitemaps dictionary.
The rest of the Google defined Sitemaps extend the basic SitemapView so they can also support the same overrides as well as defining some extra attributes. To initialize them, just add them to the sitemaps dictionary above for use in the SitemapIndex/SitemapGenerator views.

from sitemapext import MobileSitemapView

$ tox
This will take a long time to download and compile all the packages required. If you are testing database integration, make sure you have a database named "test" setup for MySQL and PostgreSQL.
You can just run the unittests at any point on the standard sqlite3 setup by running:
$ python sitemapext/runtests/runtests.py
If you are using sitemapext in your project, you can test it like any other Django app:
$ django-admin.py test sitemapext
