===================
django-allowedsites
===================
Django 1.6+ library for setting your ``ALLOWED_HOSTS`` based on the domains in ``django.contrib.sites``
.. image:: https://travis-ci.org/kezabelle/django-allowedsites.svg?branch=master
:target: https://travis-ci.org/kezabelle/django-allowedsites
Usage is something like the following, in your ``settings.py`` or equivalent::
from allowedsites import AllowedSites
ALLOWED_HOSTS = AllowedSites(defaults=('mytestsite.com',))
Or, if you want to use your cache backend::
from allowedsites import CachedAllowedSites
ALLOWED_HOSTS = CachedAllowedSites()
A single key, ``allowedsites`` will be inserted containing an unsorted collection
of all the domains that are in the ``django.contrib.sites``. For the sake of allowing
multiple processes to keep up to date with the ``Site`` values without hitting
the database, using a shared cache (ie: not ``LocMemCache``) is encouraged.
The ``CachedAllowedSites`` also provides an ``update_cache`` class method which
may be used as a signal listener::
from django.db.models.signals import post_save
from django.contrib.sites.models import Site
post_save.connect(CachedAllowedSites.update_cache, sender=Site,
dispatch_uid='update_allowedsites')
You can modify the the defaults::
from allowedsites import AllowedSites
ALLOWED_HOSTS = AllowedSites(defaults=('mytestsite.com',))
ALLOWED_HOSTS += AllowedSites(defaults=('anothersite.net',))
ALLOWED_HOSTS -= AllowedSites(defaults=('mytestsite.com',))
# ultimately, only anothersite.net is in the defaults
Other uses?
-----------
It *may* work with `django-csp`_ (Content Security Policy headers),
`django-dcors`_ (Cross-Origin Resource Sharing headers) and others. I don't know.
