Observer Subject Pattern on Rails


#1

Hi guys,

I’m developing a chat application with rails. I need to instantiate a
observer for each user that logs in the app and then, when this user
type a message update all users with the new message.

I try wiki.rubyonrails.org for help, and find nothing I can use. I
searched using the keywords rails observer and didn’t find anything
interesting.

Where can I find useful documentation?

Thanks in advance.
