Question

我有一个名为release_monitor_worker.rb的工作人员，保存在app/workers/下。看起来像这样：

class ReleaseMonitorAddWorker
  include Sidekiq::Worker
  sidekiq_options retry: false

  require 'watir'
  require 'nokogiri'
  require 'open-uri'

  def parse_url(url)
    puts "Beginning navigation to #{url}"
    browser = Watir::Browser.new :chrome, headless: true
    browser.goto url
    puts "Succesfully navigated!"
    Nokogiri::HTML.parse(browser.html)
  end

  def perform
    doc = parse_url(URL)
    count = doc.xpath('/html/body/div[9]/div/div/div/div/div[2]/div[2]/div[1]/div/div[1]/h1/span')
    count.tr('()', '')
    binding.pry
  end
end

然后我从NewReleasesController（名为new_releases_controller.rb）中调用此工作程序，如下所示：

class NewReleasesController < ApplicationController
  def index
    ReleaseMonitorAddWorker.perform_async
  end
end

我启动redis，然后启动sidekiq，然后运行rails。触发该控制器方法时出现以下错误：uninitialized constant NewReleasesController::ReleaseMonitorAddWorker

这是怎么回事？

您的类名（ReleaseMonitorAddWorker）和包含的文件名（release_monitor_worker.rb）之间不匹配。将文件重命名为release_monitor_add_worker.rb或将类重命名为ReleaseMonitorWorker都可以。
