python - Django Query sort case-insensitive using Model method with PostgreSQL

I'm really new to django, python and postgres... I can't seem to find the answer on how to order_by being case insensitive while using Model as the query method, only if you use direct SQL queries.

Model
@classmethod
def get_channel_list(cls, account):
    return cls.objects.filter(accountid=account).order_by('-name').values_list('name', 'channelid')

Data set and order it's currently being ordered in

test
b test
a test channel
a test channel
a test 2 
a b test
Test Channel
Test 3
Test 3
Test 2 Channel

any help would be much appreciated.

With django 1.8, there is a built-in solution:

from django.db.models.functions import Lower
...
ret = ret.order_by(Lower('name_lower'))
ret = ret.order_by(Lower('name_lower').asc())
ret = ret.order_by(Lower('name_lower').desc())
