在socket.io中,您可以向除发件人之外的所有客户端发送消息,例如:

socket.broadcast.emit('user connected');

但在rails/actioncable中,怎么做？

class BoardChannel < ApplicationCable::Channel
   def subscribed
     stream_from "board:#{params[:board]}"
   end

   def speak
     # client will call @perform('speak')
     result = do_something()
     # how to send 'result' to all client except sender?
   end
 end
