An extension for django.contrib.sites, featuring domain redirects and automatic population of the django.contrib.sites.Site table based on settings.

Project description

Extensions to django.contrib.sites.


  • Domain redirects: handles smart redirecting to a main domain from alias domains. Taking http/https into consideration.
  • Site auto-population: automatically populates the Domain name in django.contrib.sites.Site.domain based on the ALDRYN_SITES_DOMAINS setting.


  • add aldryn_sites to INSTALLED_APPS.
  • add aldryn_sites.middleware.SiteMiddleware to MIDDLEWARE_CLASSES (place it before djangosecure.middleware.SecurityMiddleware if redirects should be smart about alias domains possibly not having a valid certificate of their own. The middleware will pick up on SECURE_SSL_REDIRECT from django-secure.)


    1: {  # matches SITE_ID
        'domain': '',  # main domain that all domains in redirects will redirect to.
                                      # Auto populates ``django.contrib.sites.Site.domain``
        'aliases': [                  # these domains will be accessible like the main domain (no redirect).
            r'^[a-z0-9-]+\.anysub\.com$',  # regexes are supported
        'redirects': [                # these domains will be redirected to the main domain.
            '',            # add ``'*'`` to redirect all non-main domains to the main one.
            r'^[a-z0-9-]+\.my-redirect-domain\.com$',  # regexes are supported
            r'.*',  # matches any domain (Makes the above rules useless. It's just an example)

When using regexes:

  • exact matches win over pattern matches
  • pattern redirect matches win over pattern alias matches

Further Settings

set ALDRYN_SITES_SET_DOMAIN_NAME to False if you don’t want django.contrib.sites.Site.domain to be auto-populated (default: True).


  • validate settings
  • test settings validators
  • log warning if there are Sites in the database that are not in the settings
  • pretty display of how redirects will work (in admin and as a simple util)
  • regex support for aliases
  • form to test redirect logic
  • pre-compile and cache regexes
