You can do that as follow (descending) :

Article.objects.all().order_by('-slidenumber')[:5]

Ascending:

Article.objects.all().order_by('slidenumber')[:5]

You can use "pk" instead of "slidenumber" since it is a primary key

I think you are asking how to order articles? I don't see a field that allows you to get "latest" or any time derived info?

      Article.objects.all().order_by('-slidenumber')

You can obtain the last five items by slicing with:

Article.objects.order_by('-slidenumber')[:5]

The [:5] will thus retrieve only the first five items for a QuerySet that ordered the Articles in descending order by slidenumber.
