sidekiq - 警告：引發ArgumentError：錯誤的參數數目（0給出，預計2..3）

Question

它顯示了錯誤的參數數目，但我傳遞3個參數

ScannerWorker.perform_async('bob1','bob2',5) 

這裏sidekiq工人代碼

class ScannerWorker 
    include Sidekiq::Worker 

    def perform(bob1, bob2, bob3) 
    puts bob1 
    end 
end 

sidekiq版本： - 4.2.7
軌4.2.6
Redis的服務器v = 3.0.7

Sidekiq錯誤： -

Answer 1

按照此步驟
*在Gemfile中提起sidekiq版本
*殺死sidekiq過程並重新啓動sidekiq

Answer 2

您需要重新啓動Sidekiq。實時代碼重新加載只適用於Sidekiq 4.2+運行Rails 5.0+。

Answer 3

值得注意。我一直在研究類似的問題。

SomeWorker.perform_async(@user.id) 

    class SomeWorker 
    include Sidekiq::Worker 

    def perform(user_id) 
    puts "{user_id}" 
    end 
end 

確切地不確定爲什麼我得到參數錯誤。也許這是因爲一個實例變量，也許是一個軌道錯誤。
不過，我receated使用

$rails g sidekiq:worker SomeWorker 

的工人，看到這個*。

class SomeWorker 
    include Sidekiq::Worker 

    def perform(*args) 
    puts #some thing 
    end 
end 

通過添加astrix的一切工作完美。

快速回答：

class SomeWorker 
    include Sidekiq::Worker 

    def perform(*user_id) 
    puts #some thing 
    end 
end
