在 ActionCable 中未找到订阅类“MyChannel”

我在使用 Action Cable 时遇到问题，每当我运行程序时，我都会收到一条错误消息：Subscription找不到类ConversationChannel

当我尝试发送消息时，我收到此日志

成功升级到WebSocket（REQUEST_METHOD：GET， HTTP_CONNECTION：升级，HTTP_UPGRADE：websocket）订阅类 未找到：“ConversationChannel”无法执行命令 {“命令”=>“消息”, "identifier"=>"{\"频道\":\"对话频道\"}", "data"=>"{\"消息\":[{\"name\":\"conversation_id\",\"value\":\"2\"},{\"name\":\"amitian_id \",\"值\":\"1\"},{\"名称\":\"body\",\"值\":\"nmm\"}],\"操作\":\ “说话\”}”}） [运行时错误 - 无法找到具有标识符的订阅： {“频道”：“对话频道”}]： C:/RailsInstaller/Ruby2.3.​​0/lib/ruby/gems/2.3.0/gems/actioncable-5.0.1/lib/action_cable/connection/subscriptions.rb:74:infind' | C:/RailsInstaller/Ruby2.3.0/lib/ruby/gems/2.3.0/gems/actioncable-5.0.1/lib/action_cable/connection/subscriptions.rb:53:in 执行动作' | C:/RailsInstaller/Ruby2.3.​​0/lib/ruby/gems/2.3.0/gems/actioncable-5.0.1/lib/action_cable/connection/subscriptions.rb:17:inexecute_command' | C:/RailsInstaller/Ruby2.3.0/lib/ruby/gems/2.3.0/gems/actioncable-5.0.1/lib/action_cable/connection/base.rb:88:in'dispatch_websocket_message'| C:/RailsInstaller/Ruby2.3.​​0/lib/ruby/gems/2.3.0/gems/actioncable-5.0.1/lib/action_cable/server/worker.rb:58:in `调用中的块'

ConversationChannel.rb

class ConversationChannel < ApplicationCable::Channel
  def subscribed
    # stream_from "some_channel"
    stream_from "conversations-#{current_amitian.id}"
  end

  def unsubscribed
    # Any cleanup needed when channel is unsubscribed
    stop_all_streams
  end

  def speak(data)

    message_params = data['message'].each_with_object({}) do |el, hash|
      hash[el.values.first] = el.values.last
    end

    ActionCable.server.broadcast(
      "conversations-#{current_amitian.id}",
      message: message_params
    )
  end 
 end

conversation.js

App.conversation = App.cable.subscriptions.create("ConversationChannel", {
  connected: function() {

  },
  disconnected: function() {

  },
  received: function(data) {
  console.log(data['message']);
  },
  speak: function(message) {
    return this.perform('speak' , {
    message: message
    });
  }
});

$(document).on('submit', '.new_message', function(e) {
  e.preventDefault();
  var values = $(this).serializeArray();
  App.conversation.speak(values);
  $(this).trigger('reset');
});

连接.rb

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

    def connect
        self.current_amitian = find_verified_amitian
    end

    protected

    def find_verified_amitian
        if(current_amitian = env['warden'].amitian)
            current_amitian
        else
            reject_unauthorized_connection
        end
    end
  end
end

使用上面给出的日志文件谁能告诉我为什么它找不到我的conversation_channel.rb file ?

我已通过将通道文件移至一个目录来解决此问题。

From app/channels/application_cable/conversation_channel.rb to app/channels/conversation_channel.rb
