ruby-on-rails - 単純な構造が原因で Delayed_Job タスクが失敗する

Question

Rails アプリケーションでdelayed_job を使用すると問題が発生します。Struct を介して単純な (整数) ID を渡そうとすると、ジョブが失敗します。これは、現在の仕事の様子です。

  class EventJob < Struct.new(:event_id)
    def perform
      # TODO
    end
  end

perform の本体は現在空です。このようなジョブを実行すると、次の失敗エラーが発生します。

Delayed::Job.enqueue(EventJob.new(1))

エラーメッセージは次のとおりです。

Job failed to load: undefined method `members' for #. Handler: "--- !ruby/struct:EventJob \nevent_id: 1\n"

Struct.new(:event_id) を削除すると、peform メソッドが実行されます。奇妙なことに、「members」というメソッドがありません。しかし、Struct には members というメソッドがあります。delayed_job と Struct の間に何らかの互換性の問題がありますか?

ありがとう！

わかりました、何がこの問題を引き起こすのかわかりません。プロジェクトの古いバックアップバージョンに戻ったところ、再び機能するようになりました。申し訳ありませんが、それ以外の詳細な情報を提供することはできません。

あなたの YAML エンジンには何か奇妙なことが起こっていると思います。YAML::Parser 定数を確認してください。Psych::Parser である必要があります。あなたは実行できるはずです：

YAML.load "--- !ruby/struct:EventJob \nevent_id: 1\n"

あなたのirbコンソールで。
