djangotoolbox provides a common API for running Django on non-relational/NoSQL databases (currently via Django-nonrel).
In djangotoolbox.db you can find base classes for writing
non-relational DB backends. Read
Writing a non-relational Django backend
for more information.
In djangotoolbox.fields you can find several common field
types for non-relational DB backends (ListField, SetField,
DictField, RawField, BlobField).
The djangotoolbox.admin module provides admin overrides for
making django.contrib.auth work correctly in the admin UI.
Simply add 'djangotoolbox' to INSTALLED_APPS after
django.contrib.admin. This will disable features that
require JOINs. If you still need permission handling you should
use the nonrel permission backend.
