Question

我正在尝试在我的Rails项目中使用ActionCable，虽然似乎正在建立WebSocket连接但是没有消息被发送（只有ping）。

据我所知，我的CoffeeScript中的# app\channels\quiz_data_channel.rb: class QuizDataChannel < ApplicationCable::Channel def subscribed stream_from "quiz_data" end def unsubscribed # Any cleanup needed when channel is unsubscribed end方法永远不会被调用。

这是我的频道定义：

#app\assets\javascripts\channels\quiz_data.coffee:
App.quiz_data = App.cable.subscriptions.create "QuizDataChannel",
  connected: ->
    # Called when the subscription is ready for use on the server
    console.log "[AC] on click handler called?"
    $('btn btn-primary btn-lg').on 'click', console.log "[AC] on click handler called!"


  disconnected: ->
    # Called when the subscription has been terminated by the server

  received: (data) ->
    # Called when there's incoming data on the WebSocket for this channel

这是我的咖啡因：

$scope.chartConfig = {data:responseNifty};

有谁知道问题可能是什么？

这是我的第一个rails项目，任何帮助都将不胜感激。

看着你的quiz_data.coffee，你有 App.quiz_data = App.cable.subscriptions.create "QuizDataChannel"。我相信您的quiz_data_channel文件中需要quiz_data_channel.rb;您已定义stream_from "quiz_data"的位置。尝试将其更改为stream_from "quiz_data_channel"。让我知道你是如何上场的！

Rails ActionCable“连接”方法未被调用
