You can do this by setting it in the queryset attribute, for example:

from django.views.generic.list import ListView

class PortfolioListView(ListView):
    model = Portfolio
    queryset = Portfolio.objects.order_by('?')[:6]
    template_name = 'portfolio/portfolio_index.html'

you can override get_queryset method to build your custom queryset.

def get_queryset(self):
    return Portfolio.objects.order_by('?')[:6]

Note: order_by('?') queries may be expensive and slow, depending on the database backend you’re using.
