class PhotoProcessorJob < ActiveJob::Base
  queue_as :default
  def perform(*args)
    ::Photo.process_photos
  end
end

它调用我的Photo类上的方法(存储在config / initializers中)：

class Photo
  require 'zxing'
  require 'csv'

  @tablePath = Dir.glob("#{Rails.root.to_s}/tmp/photo_processing/*.csv")[0]
  @output = "#{Rails.root.to_s}/tmp/photo_data.csv"

  def self.getStudentInfo(id)
    CSV.foreach(@tablePath,headers: true) do |row|
      if row["Student ID"] == id
        return row
      else
        next
      end
    end
  end

  def self.writeInfoToFile(data,file)
    first_name = data["First Name"]
    last_name = data["Last Name"]
    student_id = data["Student ID"]
    grade = data["Grade"]
    email = data["Email"]
    photo = file.to_s
    CSV.open(@output,"a+") do |csv|
      csv << [first_name,last_name,student_id,grade,email,photo]
    end
  end

  def self.process_photos
    extensions = %w(.jpg .jpeg .png .gif .tif)
    studentInfo = nil
    newfile = false
    if File.exist?(@output)
      outfile = CSV.new(File.read(@output))
      if outfile.count == 0
        newfile = true
      end
    else
      newfile = true
    end
    if newfile
      CSV.open(@output,"wb") do |csv|
        csv << ["First Name","Last Name","Student ID","Grade","Email","Photo"]
      end
    end
    Dir.glob("#{Rails.root.to_s}/tmp/photo_processing/*").each do |file|
      if file.match(/#{extensions.join("|")}/)
        id = ZXing.decode File.new(file)
        unless id.nil?
          studentInfo = getStudentInfo(id)
        else
          writeInfoToFile(studentInfo,file) unless studentInfo.nil?
        end
      end
    end
  end

end

并从控制器调用：

class ProcessingController < ApplicationController
  def finish
    PhotoProcessorJob.perform_later
  end
end

我正在尝试使用Active Job Inline后端,因此没有安装任何队列库.问题是“完成”视图在process_photos方法运行时被延迟,而不是被发送到后台并且视图立即显示.这导致由上游过早关闭连接引起的Nginx内的502错误,可能是因为process_photos任务花费的时间太长而无法完成.

我的Active Job设置有问题吗？
