Ruby 操作电缆不适用于导轨5

我是Rails 5的初学者，我正在尝试在我的应用程序中实现web套接字。我试图复制并运行一个测试应用程序，首先，我发现它不工作，因为它没有发送和接收数据<代码>已接收：（数据）->从未被调用。我还注意到，它也从未与我的redis服务器连接（我是用brew安装的）。我正在粘贴下面的所有代码。提前谢谢

//room.coffee

App.room = App.cable.subscriptions.create "RoomChannel",
connected: -> 
# Called when the subscription is ready for use on the server 
disconnected: -> 
# Called when the subscription has been terminated by the server 

received: (data) -> 
alert(data['message'])
speak: (message) -> 
@perform 'speak', message: message

# Be sure to restart your server when you modify this file. Action 
Cable runs in a loop that does not support auto reloading.
class RoomChannel < ApplicationCable::Channel
def subscribed
 stream_from "room_channel"
end

def unsubscribed
  # Any cleanup needed when channel is unsubscribed
end

def speak(data)
  ActionCable.server.broadcast "room_channel", message: data['message']
end
end

# Action Cable provides the framework to deal with WebSockets in Rails.
    # You can generate new channels where WebSocket features live using the rails generate channel command.
    #
    # Turn on the cable connection by removing the comments after the require statements (and ensure it's also on in config/routes.rb).
    #
    #= require action_cable
    #= require_self
    #= require_tree ./channels
    #
    @App ||= {}
    App.cable = ActionCable.createConsumer()

您可以尝试在不使用Redis的情况下使用Action Cable（因为Action Cable并不严格要求使用Redis）：

但这可能不是你问题的根源。你的

房间。咖啡

缺少一些

说话

呼叫代码。添加到

room.coffee

类似的内容：

$ ->
  $('#send_form').submit (event)->
    App.room.speak event.currentTarget['message'].value
    event.currentTarget['message'].value = ""
    event.preventDefault()
    false

以下是一个模板：

<div class="jumbotron">
  <form id="send_form">
    <label>Message:</label>
    <input id="message" type="text" data-behavior="room_speaker">
    <br> 
    <input type="submit" data-behavior="room_speaker">
  </form>
</div>

信息：

尝试设置

gem'pg'

而不是

gem'sqlite3'

（和bundle安装）另请参见：我会尝试，但是设置'pg'而不是'sqlite3'1 2的原因是什么

development:
  adapter: async

test:
  adapter: async

production:
  adapter: redis

$ ->
  $('#send_form').submit (event)->
    App.room.speak event.currentTarget['message'].value
    event.currentTarget['message'].value = ""
    event.preventDefault()
    false

<div class="jumbotron">
