Exception Value: Site matching query does not exist.

do you know what is causing this error?

Edit

Following huck Harmston instructions Site.objects.get(pk=settings.SITE_ID) returned this error

In my database there's a site_id http://127.0.0.1:8000/' which is the domain name that i used instead ofexample.com`

    Do you have in your database a Site object with the id from your settings.py file? Commented Apr 10, 2012 at 11:05
  • Did you forget to run syncdb? Commented Apr 10, 2012 at 11:06
  • @burhan django-userena has 2 settings.py, one inside the demo project folder and one outside it, i did run syncdb inside the demo project folder, but i am editing the other settings.py file, there is no manage.py file to that, therefore i can't run syncdb Commented Apr 10, 2012 at 17:02

Your SITE_ID setting's value likely does not correspond with the primary key of a Site object. You can verify by running this:

$ ./manage.py shell
Python 2.7.1 [...]
>>> from django.contrib.sites.models import Site
>>> from django.conf import settings
>>> Site.objects.get(pk=settings.SITE_ID)
<Site: example.com>

If the response of the final command is not a Site object (it'd likely raise a Site.DoesNotExist exception), then that's the problem. You can solve it by not setting SITE_ID, which is unnecessary if you are not using django.contrib.sites.

I know this might sound weird, but I saw an error like this once. Try removing django.contrib.sites. It was colliding with another app that the person had installed.

It's not prudent to recommend that someone wholesale remove a dependency. They may not need the sites contrib package, but they might or one of their 3rd-party apps might need it. Besides, if a package conflicts with sites, that's a problem with that package, not sites. You shouldn't write anything that conflicts with Django's stuff, whether it's optional or not.
