I have an issue with the Sites system in Django. My problem is when running Site.objects.get_current() on some pages on initial load of the development server I get an exception saying Site matching query does not exist. however if I load the main page of the site it loads just fine then I can go back to any other page with the exception and they load fine as well.
Has anyone come across this issue before?
Thanks,

get_current looks at the current hostname and detects whether you have a Site object with a matching domain name.
Perhaps on development you are using localhost or something similar. You need to create a Site object with the same domain name, i.e., via something like this which could be added to a migration:
if settings.DEBUG: development_site_domain = 'localhost' # Or whatever yours is. Site.objects.create( name=development_site_domain, domain=development_site_domain) You must have a Site object in the database for any FQDN you access your app via. You also need to include the FQDN in your ALLOWED_HOSTS setting.
The alternative is to set SITE_ID = 1 (or any pk of an existing SITE_ID in your database). The drawback here is that your server will respond differently on local vs. on the server if you're using a dynamic SITE_ID on production.
add SITE_ID = 1 to your settings.py, and run python manage.py syncdb to create corresponding tables if not exist, this will work
and then, you could login into your admin site: click Site to modify defalut example.com to yours, this used when you edit an object, It will provide a View on site button if you defined a get_absolute_url function in your models.py
