ruby on rails - Stop sidekiq worker when user logs out -

i want perform background job when user logged in. when user logged in, start worker:

  warden::manager.after_authentication |user,auth,opts|     imapworker.perform_async(user.id)   end 

all imapworker use ruby's net::imap api wait new emails come in remote email server. uses imap's idle functionality wait new events.

class imapworker   include sidekiq::worker    def perform(user_id)     user = user.find(user_id)     imap = net::imap.new('imap.gmail.com',993,true)     imap.login(user.email, user.password)     imap.select('inbox')      imap.add_response_handler |resp|       if resp.kind_of?(net::imap::untaggedresponse) , resp.name == "exists"         check_email       end     end      imap.idle   end end 

now when user logs out, want end worker. know in devise, can hook log out functionality such:

warden::manager.before_logout |user,auth,opts|     ... end   

but how stop sidekiq worker?

require 'sidekiq/api'; sidekiq::processset.new.each(&:stop!)
