Django sitemap styling

I have several hundred thousand urls, so I would like to cache my sitemaps. This creates a sitemap just fine:

from django.contrib.sitemaps import Sitemap, views as sitemap_views

class StuffSitemap(Sitemap):
    limit = 1000

    def items(self):
        return Stuff.objects.all().order_by('date')

urlpatterns = [
    ...,
    url(r'^sitemap\.xml$', sitemap_views.index, {'sitemaps': {'stuff': StuffSitemap()}}),
    url(r'^sitemap-(?P<section>.+)\.xml$', sitemap_views.sitemap, {'sitemaps': {'stuff': StuffSitemap()}}, name='django.contrib.sitemaps.views.sitemap'),
    ...
]

      

        
        
        
      

    

Decorating the index view sitemap.xml

works fine (even with my own decorators):

from django.views.decorators.cache import cache_control

url(r'^sitemap\.xml$', cache_control(max_age=3600, public=True)(sitemap_views.index), {'sitemaps': {'stuff': StuffSitemap()}}),

      

        
        
        
      

    

But the moment I decorate the actual sitemap view, things start to break:

url(r'^sitemap-(?P<section>.+)\.xml$', cache_control(max_age=3600, public=True)(sitemap_views.sitemap), {'sitemaps': {'stuff': StuffSitemap()}}, name='django.contrib.sitemaps.views.sitemap')

      

        
        
        
      

    

Here's the complete traceback:

Internal Server Error: /sitemap.xml

Curiously, both of these views are embellished when defined:

def x_robots_tag(func):
    @wraps(func)
    def inner(request, *args, **kwargs):
        response = func(request, *args, **kwargs)
        response['X-Robots-Tag'] = 'noindex, noodp, noarchive'
        return response
    return inner


@x_robots_tag
def index(request, sitemaps,
          template_name='sitemap_index.xml', content_type='application/xml',
          sitemap_url_name='django.contrib.sitemaps.views.sitemap'):
    ....

      

        
        
        
      

    

It seems to me that the decorator is preventing the Django graphics editor from handling the decorated sitemap

view correctly , as it uses **kwargs

instead of an explicit section

kwarg:

sitemap_url = urlresolvers.reverse(sitemap_url_name, kwargs={'section': section})

      

        
        
        
      

    

But that doesn't explain why this works, as the views are already decorated. Any thoughts?
