Question

I have a Rails 3 App using Devise on Heroku. Problem is I’m sending emails with Sendgrid and email delivery is slow, it makes the app hang. So I’m interested in using delayed_job to queue the email delivery in the background so my app is responsive to the user.

How can Devise be used with delayed_job? Any way to setup Devise to use delayed_job?

Add this to a file in config/initializers directory:

module Devise
  module Models
    module Confirmable
      handle_asynchronously :send_confirmation_instructions
    end

    module Recoverable
      handle_asynchronously :send_reset_password_instructions
    end

    module Lockable
      handle_asynchronously :send_unlock_instructions
    end
  end
end
