Allow Distinct Queries

[gurelkaynak]

I'm using django-nonrel 1.6-beta with djangotoolbox. Some of my admin pages needed to use DISTINCT but djangotoolbox prevented that in /db/basecompiler.py line 451:

diff --git a/djangotoolbox/db/basecompiler.py b/djangotoolbox/db/basecompiler.py

     def get_count(self, check_exists=False):

Can somebody explain why using distinct raises this DatabaseError?

I'll also try to push this to a branch.

Thank you.

I realized that distinct queries are not supported by django_mongo_engine...

Actually they seem to be supported like this distinct('foo'). When called without arguments it doesn't work.
