def perform(*)
  fail NotImplementedError
end

#perform_now ⇒ Object

Performs the job immediately. The job is not sent to the queuing adapter but directly executed by blocking the execution of others until it’s finished. perform_now returns the value of your job’s perform method.

class MyJob < ActiveJob::Base
  def perform
    "Hello World!"
  end
end

puts MyJob.new(*args).perform_now # => "Hello World!"
