module ActiveJob::Execution

Active Job Execution¶ ↑

Provides methods to execute jobs immediately, and wraps job execution so that exceptions configured with rescue_from are handled.

Public Instance Methods

perform (*)

# File activejob/lib/active_job/execution.rb, line 60
def perform(*)
  fail NotImplementedError
end

perform_now ()

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!"

# File activejob/lib/active_job/execution.rb, line 45
def perform_now
  # Guard against jobs that were persisted before we started counting executions by zeroing out nil counters
  self.executions = (executions || 0) + 1
