Django MongoDB Engine error when running tellsiteid
You can create your site, and then, get the id:
python ./manage.py shell>>> from django.contrib.sites.models import Site>>> s = Site()>>> s.save()and then:
python ./manage.py tellsiteid
If you do not need the sites functionality (which is very probable) simply turn off django.contrib.sites app and it will fix MongoDB issues related to the SITE_ID:
INSTALLED_APPS = ( (...) # 'django.contrib.sites', # Comment this out (...))
You haven't created any Site yet. Run manage.py syncdb to create one.
