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!"
