Rails 5动作电缆Heroku-重新加载页面后电缆流停止

我希望有人有时间帮助我编写代码。一个多月以来，我一直在使用Rails 5使用Active Job in Action Cable，似乎没有人从我学习课程的地方发现我的代码中有什么错误

我正在使用的应用程序预计将显示2条flash消息 1.感谢您的评论（来自AJAX） 2.发布了一条新评论（来自Javascript频道代码）

以及更多内容（来自Javascript频道代码） 3.在新评论前加上前缀 4.刷新额定值 5.淡出闪光信息

然而，action cable仅传输第2、3、4项，以获得新的评论。页面重新加载后，操作电缆停止流式传输

我的远程回购可以在这里找到-

我的行动电缆启动代码为：

config/cable/yml
development:
  adapter: async

test:
  adapter: async

production:
  adapter: postgresql
  url: postgres://ybywuliqfewhzz:R4PgzgJ9IdaJ7_pdIlHkXaFkS2@ec2-54-235-221-102.compute-1.amazonaws.com:5432/dfuvk0kbffhdq5

服务器站点电缆代码app/assets/javascripts/channels/product.js

App.product = App.cable.subscriptions.create({channel:"ProductChannel"}, {
  connected: function() {
    // Called when the subscription is ready for use on the server
  },

  disconnected: function() {
    // Called when the subscription has been terminated by the server
  },

  received: function(data) {
    // Called when there's incoming data on the websocket for this channel
    console.log("Hello");
    $('#cable-flash').show();
    $('.product-reviews').prepend(data.comment);
    refreshRating();
    $('.alert').delay(2000).fadeOut(3000);
  },

  listen_to_comments: function() {
    return this.perform('listen', {
      product_id: $("[data-product-id]").data("product-id")
    });
  }
});

$(document).on('turbolinks:load', function() {
  App.product.listen_to_comments();
});

app/channels/product_channel.rb

class ProductChannel < ApplicationCable::Channel
  def subscribed
    # stream_from "product_channel"
  end

  def unsubscribed
    # Any cleanup needed when channel is unsubscribed
  end

  def listen(data)
    stop_all_streams
    stream_for data["product_id"]
  end
end

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

该代码在开发过程中运行良好，但在heroku手机版和桌面版中失败。在动作电缆停止传输作业后，该代码只对一条评论有效

这是我在页面重新加载后从heroku收到的日志的摘录，该日志显示产品页面停止了流式处理

你有没有想过？我也犯了类似的错误…你有没有发现？我得到了一个类似的错误。。。
