Of course, it's ugly to hard-code the site IDs like that. This sort of
hard-coding is best for hackish fixes that you need done quickly. A slightly
hard-coding is best for hackish fixes that you need done quickly. The
cleaner way of accomplishing the same thing is to check the current site's
domain::
from django.conf import settings
from django.contrib.sites.models import Site
from django.contrib.sites.models import get_current_site
def my_view(request):
current_site = Site.objects.get(id=settings.SITE_ID)
current_site = get_current_site(request)
if current_site.domain == 'foo.com':
# Do something
else:
# Do something else.
The idiom of retrieving the :class:`~django.contrib.sites.models.Site` object
for the value of :setting:`settings.SITE_ID <SITE_ID>` is quite common, so
the :class:`~django.contrib.sites.models.Site` model's manager has a
``get_current()`` method. This example is equivalent to the previous one::
This has also the advantage of checking if the sites framework is installed, and
return a :class:`RequestSite` instance if it is not.
If you don't have access to the request object, you can use the
``get_current()`` method of the :class:`~django.contrib.sites.models.Site`
model's manager. You should then ensure that your settings file does contain
the :setting:`SITE_ID` setting. This example is equivalent to the previous one::
from django.contrib.sites.models import Site
def my_view(request):
def my_function_without_request():
current_site = Site.objects.get_current()
if current_site.domain == 'foo.com':
# Do something
else:
# Do something else.
For code which relies on getting the current domain but cannot be certain
that the sites framework will be installed for any given project, there is a
utility function :func:`~django.contrib.sites.models.get_current_site` that
takes a request object as an argument and returns either a Site instance (if
the sites framework is installed) or a RequestSite instance (if it is not).
This allows loose coupling with the sites framework and provides a usable
fallback for cases where it is not installed.
.. function:: get_current_site(request)
Checks if contrib.sites is installed and returns either the current
:class:`~django.contrib.sites.models.Site` object or a
:class:`~django.contrib.sites.models.RequestSite` object based on
the request.
