Rails and Orbited

对这篇文章的补充
[url]http://fuglyatblogging.wordpress.com/2008/10/08/http-push-aka-comet-with-orbited-and-rails/[/url]

首先是配置的问题

APP_SETTINGS[:orbited_host] = 'localhost'
APP_SETTINGS[:orbited_port] = '8500'
APP_SETTINGS[:site_address] = 'localhost:3000'

这里localhost改成你的IP吧，这样你想在局域网页测试的话就可以试

其次是controller

require 'stomp'
class ChatController < ApplicationController

    def send_data
        unless params[:chat_input].empty?
            javascript = render_to_string :update do |page|
                page.insert_html :top, 'chat_data', "MESSAGE: #{h         params[:chat_input]}"
                page[:chat_input].clear
                page[:chat_input].focus
                s = Stomp::Client.new
                s.send(params[:channel],javascript)
                s.close
            end
        end

        render :nothing => true
    end
end

以我有限的知识这个怎么看都不像是对的，在javascript = xxxx 的block里面还用
s.send(params[:channel], javascript)
 
所以把      s = Stomp::Client.new
                s.send(params[:channel],javascript)
                s.close
移到render_to_string外面 就行了

总的来说用Rails + Orbited效果相当满意，挺不错的
