Rails - send all emails with a delay_job asynchronously

I use delayed_job , and I am very pleased with this (especially with the workless extension.)

But I would like to establish that ALL messages from my application are sent asynchronously.

Indeed, the solution offered for email programs

# without delayed_job
Notifier.signup(@user).deliver

# with delayed_job
Notifier.delay.signup(@user)

I am not happy because:

  • it is not easy to repair
  • letters sent from precious stones are not sent asynchronously ( devise , mailboxer )

I could use this kind of extension https://github.com/mhfs/devise-async , but I would rather find out a solution for the whole application right away.

ActionMailer, .deliver (, qaru.site/questions/744958/..., 4 , doc )?

Ruby 1.9 Rails 3.2 activerecord.

Notifier :

class Notifier

  def self.deliver(message_type, *args)
    self.delay.send(message_type, *args)
  end

end

:

Notifier.deliver(:signup, @user)

, resque sidekiq.
