Sidekiq 工人阶级不使用 CarrierWave Upload

Question

我正在尝试在某些图像处理上运行延迟作业并且遇到了一些问题。

在创建操作中，我首先创建了一个没有图像属性的新实例，因此模型值在上传器中可用。然后调用后台作业进行图片上传/处理。

def create
  @photo = Photo.new(photo_params.except("image"))
  UploadsWorker.perform_async(@photo.id)
  # @photo.image = photo_params.delay.delete("image")
  if @photo.save
    flash[:notice] = "Your new photograph is being processed."
    redirect_to @photo
 else
   flash[:notice] =  "Check the fields marked with an orange flag."
   render 'new'
 end

结束

通过将图像调用移动到 Worker 类中，我认为 params 哈希现在不可用。该页面仅使用上传器中设置的默认图像加载，但从未出现过新的缩略图，表明从未进行过处理和版本控制。

class UploadsWorker
  include Sidekiq::Worker
  sidekiq_options retry: false

  def perform(photo_id)
    photo = Photo.find(photo_id)
    photo.image = photo_params.delay.delete("image")
 end

end

---如果我注释了perform方法中的所有代码仍然会报错。

这是 Sidekiq 的一些日志输出：

Answer 1

您将 nil 传递为 worker 中的 photo_id 参数，因为 Photo 尚未保存：

"args"=>[nil]

我认为在您的情况下使用carrierwave_backgrounder 处理后台图像会更好。
