How to create Django like button for anonymous users?

Question

I am using Django and my website has no user profiles so all are anonymous. I want to implement a 'like' system. How do I restrict a user to like only once. Thanks.

If you don't have any way of identifying your users then your best bet is to store this info in a browser cookie or HTML5 local storage. (I don't advise using flash cookies since there is a long debate about them and they are harder to implement)
