Sidekiq schedule same worker to queue when done

问题

I am using Sidekiq with Rails 3, with the following worker class:

class BotWorker
   include Sidekiq::Worker

   def perform(user_id)
      user = User.find(user_id)
      puts user.email

      if condition # always true for now
           BotWorker.perform_in(1.hour, user_id) # not working
      end
   end
end

My controller simply has

BotWorker.perform_async(user_id)

However, on the Sidekiq dashboard, it doesn't seem like another worker is scheduled.

Also would like to note that the recurrence is conditional so it doesn't seem like I can use sidetiq or some sidekiq scheduling extension.

Still new to Sidekiq, read the documentation. What am I missing?

回答1:

Strange. I do the same thing except use self.class instead of BotWorker and it works. I don't have any arguments for my perform method though.

You might want to wrap your method in a begin/rescue/ensure block and move the re-queuing into the ensure block.

If User.find fails to find a user, it's going to raise an error which Sidekiq will catch and should move your job into the Retry queue. Probably not what you want.
