Question

我目前遇到的问题是，在我的Rails应用中使用Sidekiq引发了循环依赖性错误。只有在使用perform_async时才会引发此问题，否则会成功运行。

以下是问题的简化演示。

Sidekiq工人：

# app/workers/normalize_fsbo_worker.rb

class NormalizeFSBOWorker
  include Sidekiq::Worker
  def perform(property_id)
    puts property_id
  end
end

Raketask：

# lib/tasks/normalize.rake

require 'rake'
namespace :hh do
    namespace :normalize do
        desc "Async normalize all fsbo"
        task :fsbo_properties => [:environment] do |t, args|
          Property.where('fsbo IS NULL').find_in_batches do |group|
            group.each do |property|
              NormalizeFSBOWorker.perform_async(property.id) # Circular Dependency error
              # NormalizeFSBOWorker.new.perform(property.id)   # Works
            end
          end
        end
    end
end

控制台：

$ be rake hh:normalize:fsbo_properties

那是怎么回事？这个循环引用在哪里？为什么不用#new.perform？

引用它

Sidekiq循环依赖性仅在执行异步时出错
