Options

:wait - Enqueues the job with the specified delay
:wait_until - Enqueues the job at the time specified
:queue - Enqueues the job on the specified queue

Examples

class SiteScrapperJob < ActiveJob::Base
  rescue_from(ErrorLoadingSite) do
    retry_job queue: :low_priority
  end

  def perform(*args)
    # raise ErrorLoadingSite if cannot scrape
  end
