I use Django and my site does not have user profiles, so everyone is anonymous. I want to implement a "similar" system. How to restrict the user only once. Thank.
Unless you have a way to identify your users, it is best to store this information in a cookie browser or HTML5 local storage . (I don’t recommend using flash cookies because they have a lot of discussion and are harder to implement)

Still in its infancy, there is a project called django-like-buttonthat provides a wrapper for the XFBML facebook button. If you use pip and virtualenv, you can pip install django-like-buttonfollow the instructions for installing readme.rst. The project can be found on github.
