Sidekiq with Rails 4 on Cloud9 Dev and Heroku Production

Question

I am just not understanding how this works and need help. What I have done...

I have installed the sidekiq gem, I have added to the application.rb file

class Application < Rails::Application
  # ...
  config.active_job.queue_adapter = :sidekiq
end

I have created a Job(not sure if this was necessary as I am using ActionMailer only right now)

rails generate job Example

I have added #deliver_later to the actionmailer

if po_collection.empty? == false
      VendorSender.open_order_sender(user, vendor, po_collection).deliver_later
end

Am I missing anything here? How do I know it is working? Also, server log seems like it is working, but I am still waiting for emails to be sent.

Answer 1

You have to run

bundle exec sidekiq

from the root of your rails project. You will see the jobs being processed in that window if it is working.
