ActionCable 部署到 test 环境功能失效

pain — Fri, 07 Aug 2015 14:44:55 +0800

本地环境功能已正常运行。发布到 test 环境后，前台无反应。test 环境 redis，puma 正常，后台可以看到广播发送了。这是我的前端订阅消息的代码：

var Notices = React.createClass({
  getInitialState: function() {
    return {
      requests: []
    };
  },

  renderRequest: function(request) {
    return (
      <li>
        <a href="#">
          <div>
            <i className="fa fa-tasks fa-fw"></i> {request.id}
            <span className="pull-right text-muted small">{request.created_at}</span>
          </div>
        </a>
      </li>
    );
  },

  componentDidMount: function() {
    this.setupSubscription();
  },

  updateRequests: function(request) {
    var requests = React.addons.update(this.state.requests, { $push: [request]});
    this.setState({requests: requests, style: {color: 'red'}});
  },

  setupSubscription: function(){
    App.requests = App.cable.subscriptions.create("RequestsChannel", {
      received: function (data) {
        this.updateRequests(data.request);
      },

      updateRequests: this.updateRequests
    });
  },

  check: function() {
    this.setState({style: {color: ''}});
  },

  render: function() {
    return (
      <div onClick={this.check}>
        <a className="dropdown-toggle" data-toggle="dropdown" href="#" style={this.state.style}>
          <i className="fa fa-bell fa-fw"></i>{this.state.requests.length > 0 ? this.state.requests.length : null}
        </a>
      </div>
    );
  }
});

求指导！如果需要额外信息请留言。

ActionCable channel 不传输消息

pain — Mon, 03 Aug 2015 17:36:08 +0800

channel.rb 文件：

module ApplicationCable
  class Channel < ActionCable::Channel::Base
  end
end

notifications_channel.rb 文件：

class NotifictionsChannel < ApplicationCable::Channel
  def subscribed
    stream_from 'notifications'
  end
end

发布广播的代码：

def create
    ActionCable.server.broadcast 'notifications',
      message: params[:notification][:body]

    head :ok
  end

订阅的代码：

App.notifications = App.cable.subscriptions.create 'NotifictionsChannel',
  received: (data) ->
    alert(data.message)
    $('#notifications').append @renderNotification(data)
  renderNotification: (data) ->
    "<p>#{data.message}</p>"

我可以确定我的其他配置是正确的，因为同样地配置在另一个独立项目里是 ok 的。在这里后台提示: [ActionCable] Broadcasting to notifications: {:message=>"12"} 但似乎订阅这里一直收不到 notification channel 的消息。求助！
