Рельсы 5: Javascript без пробега в производстве

Question

У меня есть файл js в app / assets / javascript / посещения. js .coffee

    $(document).ready ->
      worker_cache = {}
      $('#visit_client_id').change ->
        client_id = $(this).val()
        if worker_cache[client_id]
          p(worker_cache[client_id])
        else
          $.get('/workers?client_id=' + client_id, (workers) ->
            worker_cache[client_id] = workers
            p(worker_cache[client_id])
          )
     p = (workers) ->
       $('#visit_worker_id').html("")
       for worker in workers
         $('#visit_worker_id').prepend("<option value='" + worker.id + "'>" + worker.name + "</option>")

, который изменяет форму visit.agent в зависимости от выбранного агентства. (следующая эта ссылка )

моя проблема при попытке запустить этот скрипт с сервера (производство).

вот что я сделал до сих пор:

1.

rails yarn:install

$rake assets:clean'

$rails assets:precompile RAILS_ENV=production

изменить приложение. js, production.erb, файлы Gemfile, например:

production.erb

  # Disable serving static files from the `/public` folder by default since
  # Apache or NGINX already handles this.
  config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present?

  # Compress JavaScripts and CSS.
  config.assets.js_compressor = :uglifier
  # config.assets.css_compressor = :sass

  # Do not fallback to assets pipeline if a precompiled asset is missed.
  config.assets.compile = true

  # `config.assets.precompile` and `config.assets.version` have moved to config/initializers/assets.rb

application. js

//= require jquery

//= require rails-ujs
//= require jquery-ui/widgets/autocomplete
//= require jquery-ui/widgets/sortable

//= require cocoon
//= require activestorage
//= require_tree .
