Django and asynchronous client-server requests state of the art

I am planning to build a site for a realtime and/or turn-based game mainly to improve my skills (but I do not exclude to release it in the future). The main framework will be Django, but I'll have to face the problem of implementing asynchronous client-server requests. I've searched the internet and found many different solutions proposed in a wide range of time, but some are no more maintained, others really abstruse and so on...

So, my question is: what is/are the current state of the art to solve this situation? Which are the most common patterns adopted?

I attach a short list of some solutions I found but I can't evaluate how good they are:

• 
  

  Django + Node.js and socket.io + Redis (in order to connect Django and Node.js, still not completely understood how).

  
  


• 
  

  django-socketio and other similar python modules (which all seems to be discontinued).

  
  


• 
  

  Django + Tornado + Tornadio2.
