Has anyone had any success getting "realtime" message passed to the browser in Rails? I''m wondering if there''s a helper or Prototype snippet that can help pass messages to a "status" window. Basically, I have an app that is doing system tasks, like running command-line scripts and tailing logfiles. I want to show the output in near-realtime, similar to what a user would see in a command-line terminal window. Any ideas?

I wouldn''t tweak my server (and the prototype Ajax objects) just for a Status panel. Use periodically_call_remote to repeatedly call the status action on the server. That''s slow, and high-bandwidth, but completely stable. My Chat post tells generally how. Tip: Have one periodically_call_remote per page, and let it update anything that needs updating, via render :update. -- Phlip http://c2.com/cgi/wiki?ZeekLand <-- NOT a blog!! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Re: Real-time message passing to browser in Rails?
Just a little thing to keep in mind: Keeping network sockets open can quickly saturate your server''s network stack and degrade performance to the point where no new connections are accepted and the server grinds to a halt. I am not sure what your user base is, but if you are expecting it to be in the thousands, all connected with open sockets, then you should really check what the upper socket limits for your server''s network stack are. At the very least you should kill inactive sockets after a timeout. I have not used either of the solutions mentioned in the replies but it is highly likely that the have an idle timeout setting. -christos On 24 Jan 2007, at 21:21, Nate wrote:> > Has anyone had any success getting "realtime" message passed to the > browser in Rails?
