@ibugs 网站是不是挂了。。。。。

已读，受益匪浅

新年快乐。。。。。。哈

#1 楼 @jimrokliu 嗯嗯，谢谢，我也通过变通实现了这个需求，解决不了只好先绕过去。。

解决了 https://github.com/jamesotron/faye-rails/issues/58

回来结贴，修改 gem faye-rails lib/faye-rails/middleware.rb

       options = DEFAULTS.merge(options)
-      Faye::WebSocket.load_adapter(options.delete(:server))
+      server = options.delete(:server)
+      Faye::WebSocket.load_adapter(server) if server && server != 'passenger'

       @adapter = FayeRails::RackAdapter.new(@app, options)
       @adapter.instance_eval(&block) if block.respond_to? :call

在 appllication 下配置为

config.middleware.use FayeRails::Middleware, mount: '/faye', :timeout => 25,server:'passenger', engine: {type: Faye::Redis, host: 'localhost'} do
  map '/chat' => RealtimeChatController
  map default: :block
end

会 error.log 报这个错

有人碰到过这种问题么，求助啊

试着配置 nginx，会报错 WebSocket connection to 'ws://192.168.1.107/faye' failed: Error during WebSocket handshake: Unexpected response code: 301

location /faye/ {
     proxy_pass http://192.168.1.107;
     proxy_http_version 1.1;
     proxy_set_header Upgrade $http_upgrade;
     proxy_set_header Connection $connection_upgrade;
 }

#1 楼 @jimrokliu nginx version: nginx/1.6.0 websocket 该如何配置，有没有推荐的网址，谢谢

大赞，很漂亮

我是来看妹子的

楼主，我竟然看完了，你还有没有节草．．．．．．

@moliliang 不知道如何解决的？同样的问题，同纠结

看着不错，mark 一下

#11 楼 @bingoo 有

#8 楼 @Rei 点击 link

<p><%= link_to "站内信",check_messages_path,:style => "color:red" %>

routes

get 'check_messages'=>'users#check_messages'

这个会执行两次，如果只是刷新 check_messages 页面的话是只执行一次

def check_messages
  @messages=Message.where(:receive => current_user.id.to_s).order(id: :desc)
  for i in @messages

      if i.status_one=="1"
        i.status="1"
      else
        i.status_one="1"
    end
    i.save
  end
end

#6 楼 @kai209209 我试了，如果注释掉

 gem 'turbolinks'
//= require turbolinks

方法只执行一次，可以实现，turbolinks 应该是最新的，不知道具体原因． 看了@Rei 的这篇文章 http://chloerei.com/2013/07/14/turbolinks-guide/ 不知道@Rei 清楚么

#3 楼 @xiaoronglv

for i in @messages
    if i.status_one=="1"
      i.status="1"
      else
      i.status_one="1"
    end
  i.save
end

我这里想要实现的效果是站内信的功能，@messages为从数据库取出符合的信息，第一次接收到信息并进去 messages 页面，信息标志为 new，再次刷新页面，信息标志为已读，status_one 默认为空，不知道为何会执行两次，直接就置为已读状态，后来我又添加了一个属性，功能是可以实现了

    for i in @messages
 if i.sender=="1"
        if i.status_one=="1"
          i.status="1"
          else
          i.status_one="1"
        end
      i.save
else
i.sender="1"
    end

代码写的不好看，见谅

可以用paperclip

mark 一下，最近正在看元编程，看完之后再看这个

赞一个，想学学 mruby

谢谢大家的热心回答，了解了下 moxie，由于时间的关系没有使用，后来使用了@aptx4869 提供的 js，可能是新手的原因，很多地方弄不很清楚，弄了两天也没有达到需求，由于时间关系今天不得已放弃这个了想法，又回到的继续先上传在处理的方式，如果最近能有时间会继续回头做做这块，再次谢谢大家

#16 楼 @Rei 多谢

#12 楼 @PengEdy 我这个问题解决了，因为路径的问题，不清楚原因，原来图片存到 assets 下现在改为 :url => '/images/:id/:style/:basename.:extension', :path => ':rails_root/public/images/:id/:style/:basename.:extension' 就可以了
