Best way to implement view count logic in Django

Question

I've been building my personal blog using Django and I must say that I'm learning a great deal. One of those things being the fact that the implementing the view count logic is not as simple as doing view_count += 1. So far, I've done some research and narrowed my options to

1. Using Django's F-expression
2. Using django-hitcount module
3. Learn more about how sessions work and see if I can make it work with Django's sessions.

The reason I ask this is that I want to implement a more Youtube like logic for my posts. Users must view the article for a certain length (time or word wise).

What do you think is the best way to go about this? Any references to helpful articles are greatly appreciated.

Thanks!
