Question

我希望有人有时间帮我处理我的代码。我一直坚持使用Rails 5使用Active Job in Action Cable一个多月了，似乎没有人在我的代码中发现我的课程有什么问题。

我正在处理的应用程序预计会显示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）

以及更多来自（来自Javascript频道代码） 3.添加新评论 4.刷新Raty评级 5.淡出flash消息

但是，动作电缆仅传输2,3,4项新评论。重新加载页面后，操作电缆将停止流式传输。

我可以在此处找到我的远程仓库 - Sample Application

示例应用可在此处找到：Demo Application

我的行动电缆的起始码是：

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();
});

应用程序/信道/ 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

应用程序/信道/ application_cable / channel.rb

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

应用程序/信道/ application_cable / connection.rb

module ApplicationCable
  class Connection < ActionCable::Connection::Base
    identified_by :current_user

    def connect
      self.current_user = find_verified_user
    end

    def disconnect

    end

    protected

      def find_verified_user
        if verified_user = request.env['warden'].user
          verified_user
        else
          reject_unauthorized_connection
        end
      end
  end
end

config / environments / production.rb摘录

 config.action_cable.url = "wss://cfbikeberlinapp.herokuapp.com/cable"
  config.action_cable.allowed_request_origins = ['https://cfbikeberlinapp.herokuapp.com','https://cfbikeberlinapp.herokuapp.com']
end

代码在开发中完美运行但在移动和桌面的heroku中失败，它仅适用于一个注释，在该操作电缆停止传输作业之后。

这是我在重新加载页面后从heroku收到的日志的摘录，显示产品页面已停止流式传输。
