我有一个名为 Scanner 的模型，其目的是通过主动存储上传一个 xlsx 文件，然后在后台使用 sidekiq 和 roo gem 处理该文件以创建一个新的 txt 文件。该过程运行良好。我被卡住的部分是在读取 xlsx 文件的过程中，我想在显示视图中显示分析的行数，直到完成生成 txt 文件，这就是为什么我正在实施动作电缆但仍然无法正常工作的原因。这里的代码：

显示视图

请任何帮助，在此先感谢。

/app/models/scanner.rb

class Scanner < ApplicationRecord
  has_one_attached :target_file
  has_many_attached :documents

  after_create_commit do 
    ScannerBroadcastJob.perform_later(self)
  end
end

/app/jobs/scanner_broadcast_job.rb

class ScannerBroadcastJob < ApplicationJob
 queue_as :default

  def perform(scanner)
    ActionCable.server.broadcast('scanners_channel', {
      analized_rows: render_analized_rows(scanner)
    })
  end

  private
    def render_analized_rows(scanner)
      ApplicationController.renderer.render(partial: 'scanners/scanner', 
      locals: { scanner: scanner })  
    end
 end

/app/channels/scanner_channel.rb

 class ScannerChannel < ApplicationCable::Channel
   def subscribed
    stream_from "scanners_channel"
   end

   def unsubscribed
   end

   def create(data)
     Scanner.create({ analized_rows: data['analized_rows'] })
   end
end

/app/assets/javascripts/channels/scanner.coffee

App.scanner = App.cable.subscriptions.create "ScannerChannel",
  connected: ->
  disconnected: ->
  received: (data) ->
    $("#analized_rows").append(data["analized_rows"])  
  create: (analized_rows) ->
    @perform 'create', analized_rows: analized_rows

/app/views/scanners/_scanner.html.erb
