アプリでバックグラウンドタスクを実行するために遅延ジョブを使用しています。それはいくつかのことをしてからメールを送ります。これは、遅延ジョブとして実行されたコードブロックの例です。
def task
# do stuff
AppMailer.post.some_template(@variable)
end
これは正常に機能しています。正しいディレクトリsome_template.text.plain.erbにテンプレートがあります。これによりMissingTemplate例外が発生するのがわかり始めました。これにより、遅延ジョブが停止し、指定された時間が経過すると再試行します（遅延ジョブで例外が発生した場合に予想されます）。これが2〜3回失敗して正常に配信される場合もあれば、例外が発生しない場合もあります。テンプレートが存在しない場合、次の試行で正常に検出するにはどうすればよいですか？
テンプレートを探しているときにエラーが発生し、この問題.erbが発生しています。plain.text.erbこれが断続的な問題を引き起こしている理由はありますか？例外を発生させるよりもメールを送信したくないので、メールの送信をレスキューブロックでラップしようとしました。
def task
# do stuff
begin
AppMailer.post.some_template(@variable)
rescue ActionView::MissingTemplate => e
# do stuff
end
end
しかし、例外はまだ発生しています。遅延した仕事は、このレスキューブロックの動作を停止させる可能性のあることをしますか？
これがスタックトレースです
