This is my first processing jobs asynchronously I am implementing Sidekiq for background processing in my app. I will use it for reminder emails and in-app notifications. I am confused as to whether I should use Active Job to create a job that sends an email or a Sidekiq Worker to send an email. They seem to do the same thing and Rails 4.2 Active Job seems very new…is it replacing the need for a Sidekiq Worker?
Below is the same sending a mailer code using an Active Job job and a Sidekiq Worker. I am using Whenever gem for scheduling.
my_mailers.rb
class MyMailers < ActionMailer::Base
def some_mailer(r.user_id)
@user = User.find(r.user_id)
mailer_name = "ROUNDUP"
@email = @user.email
@subject ="subject text"
mail(to: @email,
subject: @subject,
template_path: '/notifer_mailers',
template_name: 'hourly_roundup.html',
)
end
end
Using a Sidekiq "Worker"
some_worker.rb
class SomeWorker
include Sidekiq::Worker
def perform()
@user = User.all
@reminders = @user.reminders.select(:user_id).uniq.newmade
@reminders.each do |r|
MyMailers.some_mailer(r.user_id).deliver_later
end
end
end
Using an Active Job "Job"
some_job.rb
class SomeJob < ActiveJob::Base
queue_as :mailer
def perform()
@user = User.all
@reminders = @user.reminders.select(:user_id).uniq.newmade
@reminders.each do |r|
MyMailers.some_mailer(r.user_id).deliver_later
end
end
end
Both Examples in my Whenever scheduler schedule.rb
require File.expand_path(File.dirname(__FILE__) + "/../config/environment")
set :path, Rails.root
set :output, Rails.root.join('log', 'cron.log')
#using a worker
every 1.day, :at => '4:30 am' do
runner SomeWorker.perform_async
end
#using a job
every 1.day, :at => '4:30 am' do
runner SomeJob.perform_async
end
