Django MongoDB Engine error when running tellsiteid

문제
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):

해결책
You haven't created any Site yet. Run manage.py syncdb
to create one.
다른 팁
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
(...)
)
have you tried this: http://django-mongodb.org/troubleshooting.html#site-id-issues
For some reason none of the solutions here worked for me. python ./manage.py tellsiteid
, there was no django_site
collection, and commenting out 'django.contrib.sites'
caused weird errors.
Grabbing the ID from the shell worked for me though, detailed here:
https://gist.github.com/ielshareef/2986459 or here Site matching query does not exist
python ./manage.py shell
>>> from django.contrib.sites.models import Site
>>> Site().save()
>>> Site.objects.all()[0].id
u'4fe7aa759e654e2662000000'
Put it in settings.py
and everything worked great!
I ran into this during my setup the other day.
Basically you need to logo into a mongo shell and lookup your siteid then add it your settings.py
log into a mongo shell
mongo
select your db
use *name*
then do a find() on django_site
db.django_site.find()
Then open your settings.py and edit the site_ID ="" line (mine is below)
SITE_ID = u'4f1f82011d41c81e5c00001d'
That should get you up and running
Most likely you havent created a site yet, to do so you need to run the command
python manage.py syncdb
This creates the site, now you need to add its site_id in your settings file. Go get the site id, connect to mongodb engine that is running, and run the following commands
use mydatabase --/# or whatever name you have for your database.
db.django_site.find()
you will get something like
ObjectId("4f4e968adea3b3b30c00001d")
then in your settings file, put
site_id = u'4f4e968adea3b3b30c00001d'
and the admin interface should work. Does it?
I use manage.py syncdb
and then manage.py tellsiteid
but still display error.
I finally solve it by dropping the database and sync again.
Hope this can help someone:)
sudo python manage.py shell
from django.contrib.sites.models import Site
Site().save()
Site.objects.all()[0].id
u'53aa6456984edd0d5e547e03'
Put it in settings.py SITE_ID = u'53aa6456984edd0d5e547e03'
