django-nonrel google app engine order_by('?')

Question

I am working on a django-nonrel app in Google App Engine.

I am trying to return items from a database in a random order. So I might have 100 items in my Items model. I wish to return a random selection of 20 items.

I have tried using:

Items.objects.order_by('?')[:20]

Except I get the following error:

Randomized ordering isn't supported by the backend

I take it this is a limitation of django-nonrel on GAE?

Is there an alternative method I could use for django-nonrel on GAE to get the same effect?

Answer 1

I've manage to find a workaround for this.

I just used python's random.shuffle(LIST_ITEM) as a way fo doing this.

It was actually very simple in the end.
