aldryn-sites

Extensions to django.contrib.sites.

Features

• 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.

Installation

• 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.)

configure ALDRYN_SITES_DOMAINS:

ALDRYN_SITES_DOMAINS = {
    1: {  # matches SITE_ID
        'domain': 'www.example.com',  # 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).
            'an.other.domain.com',
            r'^[a-z0-9-]+\.anysub\.com$',  # regexes are supported
        ],
        'redirects': [                # these domains will be redirected to the main domain.
            'example.com',            # add ``'*'`` to redirect all non-main domains to the main one.
            'example.ch',
            'www.example.ch',
            r'^[a-z0-9-]+\.my-redirect-domain\.com$',  # 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).

TODOS

• 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
