Change SITE_ID on the fly in django

I need dynamic SITE_ID in one of my websites (tspot), because of different domains and languages in it. I don’t want more threads, I just want to have different SITE_ID for different domains.

So… I need to create custom middleware.

Let’s do it.

cd /home/workspace/tspot
mkdir middleware
cd middleware
vim SiteIdOnFlyMiddleware.py

and add there:


from django.conf import settings

class SiteIdOnFlyMiddleware:
	def process_request(self, request):
		host = request.META.get('HTTP_HOST')

		if 'en.tspot.pl' in host:
			settings.SITE_ID = 2
		else:
			settings.SITE_ID = 1

now we need to add this middleware to our settings.py

cd ..
vim settings.py

and add ‘tspot.middleware.SiteIdOnFlyMiddleware.SiteIdOnFlyMiddleware’, to MIDDLEWARE_CLASSES
so it should looks like:


MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'tspot.middleware.SiteIdOnFlyMiddleware.SiteIdOnFlyMiddleware',
    'django.middleware.locale.LocaleMiddleware',
)

now restart an app.

That’s all.

This doesn’t work with the CurrentSiteManager.

Ok, my middleware is:

class SiteResolutionMiddleware(object):

def process_request(self, request):
site_id = request.session.get(“site_id”, -1)
if site_id == -1 or settings.SITE_ID == -1:
request.session["site_id"] = 2
settings.SITE_ID = 2

I set SITE_ID to -1 in settings.py.

I create an object with site_id=2 but when I do:

object_list = MyObject.on_site.all()

It’s empty. settings.SITE_ID is still -1.

Cheers

first of all, u cant change django`s settings on the fly. u must use threading, all django`s things will work, but its threads….
or u can use smthng like request.SITE_ID for each request.
