  • I'm having the same problem. My best guess so far is that it has something to do with incompatible versions of django-mongodb and djangotoolbox - anyone have any insights? – Herman Schaaf Mar 26 '12 at 10:12

I managed to fix the same error by using these packages on github:

https://github.com/django-nonrel/django-nonrel
https://github.com/django-nonrel/djangotoolbox

instead of the ones recommended on Django-Mongodb's setup page. Also, make sure to use the master branch of each, so as to not run into compatibility problems. If you're using pip, you can either pip install each of the following lines separately, or put them into your version of a requirements.txt file for your project:

git+https://github.com/django-nonrel/django-nonrel@master
git+https://github.com/django-nonrel/djangotoolbox@master
git+https://github.com/django-nonrel/mongodb-engine@master

And then run 

pip install -r requirements.txt

  • @Burak Things might have changed since I posted this, but it seems to have solved the problem for a number of people. Maybe just check that you uninstalled the original versions first, before installing the new ones, and that you're not accidentally still running the broken version from pip. – Herman Schaaf Oct 12 '12 at 15:44
  • Yes, maybe. I will try again. – Burak Oct 13 '12 at 09:28
