Overview

The MessageDelivery class is used by Base when creating a new mailer. MessageDelivery is a wrapper (::Delegator subclass) around a lazy created Mail::Message. You can get direct access to the Mail::Message, deliver the email or schedule the email to be sent through Active Job.

Notifier.welcome(User.first)               # an ActionMailer::MessageDelivery object
Notifier.welcome(User.first).deliver_now   # sends the email
Notifier.welcome(User.first).deliver_later # enqueue email delivery as a job through Active Job
Notifier.welcome(User.first).message       # a Mail::Message object

Instance Method Details



  

    #deliver_later(options = {})  
  



  

    

Enqueues the email to be delivered through Active Job. When the job runs it will send the email using #deliver_now.



Notifier.welcome(User.first).deliver_later
Notifier.welcome(User.first).deliver_later(wait: 1.hour)
Notifier.welcome(User.first).deliver_later(wait_until: 10.hours.from_now)



Options:


  • 

    :wait - Enqueue the email to be delivered with a delay.
    

  • 

    :wait_until - Enqueue the email to be delivered at (after) a specific date / time.
    

  • 

    :queue - Enqueue the email on the specified queue.
    




By default, the email will be enqueued using DeliveryJob. Each Base class can specify the job to use by setting the class variable delivery_job.



class AccountRegistrationMailer < ApplicationMailer
  self.delivery_job = RegistrationDeliveryJob
end

def deliver_later(options = {})
  enqueue_delivery :deliver_now, options
end


  








  

    #deliver_later!(options = {})  
  



  

    

Enqueues the email to be delivered through Active Job. When the job runs it will send the email using #deliver_now!. That means that the message will be sent bypassing checking perform_deliveries and raise_delivery_errors, so use with caution.



Notifier.welcome(User.first).deliver_later!
Notifier.welcome(User.first).deliver_later!(wait: 1.hour)
Notifier.welcome(User.first).deliver_later!(wait_until: 10.hours.from_now)



Options:


  • 

    :wait - Enqueue the email to be delivered with a delay
    

  • 

    :wait_until - Enqueue the email to be delivered at (after) a specific date / time
    

  • 

    :queue - Enqueue the email on the specified queue
    




By default, the email will be enqueued using DeliveryJob. Each Base class can specify the job to use by setting the class variable delivery_job.



class AccountRegistrationMailer < ApplicationMailer
  self.delivery_job = RegistrationDeliveryJob
