Best practice on structuring asynchronous mailers (using Sidekiq)
- by gbdev
Just wondering what's the best way to go about structuring asynchronous mailers in my Rails app (using Sidekiq)? I have one ActionMailer class with multiple methods/emails...
notifier.rb:
class Notifier < ActionMailer::Base
default from: "\"Company Name\" <[email protected]>"
default_url_options[:host] = Rails.env.production? ? 'domain.com' : 'localhost:5000'
def welcome_email(user)
@user = user
mail to: @user.email, subject: "Thanks for signing up!"
end
...
def password_reset(user)
@user = user
@edit_password_reset_url = edit_password_reset_url(user.perishable_token)
mail to: @user.email, subject: "Password Reset"
end
end
Then for example, the password_reset mail is sent in my User model by doing...
user.rb:
def deliver_password_reset_instructions!
reset_perishable_token!
NotifierWorker.perform_async(self)
end
notifier_worker.rb:
class NotifierWorker
include Sidekiq::Worker
sidekiq_options queue: "mail"
def perform(user)
Notifier.password_reset(user).deliver
end
end
So I guess I'm wondering a couple things here...
Is it possible to define many "perform" actions in one single worker? By doing so I could keep things simple (one notifier/mail worker) as I have it and send many different emails through it. Or should I create many workers? One for each mailer (e.g. WelcomeEmailWorker, PasswordResetWorker, etc) and just assign them all to use the same "mail" queue with Sidekiq.
I know it works as it is, but should I break out each of those mail methods (welcome_email, password_reset, etc) into individually mailer classes or is it ok to have them all under one class like Notifier?
Really appreciate any advice here. Thanks!
