Django MongoDB Engine error when running tellsiteid

Question

SO I created a django project and app as per the tutorial and I have all the dependencies necessarry for MongoDB Engine it all seemed to be working fine and dandy till I tried enabling the admin interface.

I uncommented the require bits, and added 'django_mongodb_engine' and 'djangotoolbox' to the apps section in settings.py

When I try to get into localhost:8000/admin I get an error:

"AutoField (default primary key) values must be strings representing an ObjectId on MongoDB (got u'1' instead). Please make sure your SITE_ID contains a valid ObjectId string."

After some googling apparently I have to run manage.py tellsiteid and it'll spit me an ID I can use within my settings.py that will make the error go away, but when I try to run manage.py tellsiteid I get:

Traceback (most recent call last):

Answer 1

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

Answer 2

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
    (...)
)
