Devise not sending emails after upgrading to Rails 5

Question

I am having issues to get Devise working after upgrading from Rails 4.2 to 5. Running on Rails 4 everything worked like a charm, but post update no notifications were sent in development and production. Initially, I left all the settings as they were - once aware of the problem I made a few changes, and this is what I have at the moment (Please note I re-run the devise installer at some point, which replaced the initializer/devise.rb)

development.rb

Rails.application.configure do
  ..
  config.action_mailer.raise_delivery_errors = true
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.perform_deliveries = true
  config.action_mailer.default :charset => "utf-8"
  config.action_mailer.perform_caching = false
  config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }
end

initializers/devise.rb

  # ==> Mailer Configuration
  # Configure the e-mail address which will be shown in Devise::Mailer,
  # note that it will be overwritten if you use your own mailer class
  # with default "from" parameter.
  config.mailer_sender = 'noreply@mydomain.com'

  # Configure the class responsible to send e-mails.
  config.mailer = 'Devise::Mailer'

  # Configure the parent class responsible to send e-mails.
  config.parent_mailer = 'ActionMailer::Base'

I also followed the instructions issued by devise (ie extending routes, etc.)

The only specialty that had been added is that I am using Active Job to deliver ActionMailer messages and therefore added this to my User Model to override send_devise_notification :

def send_devise_notification(notification, *args)
  devise_mailer.send(notification, self, *args).deliver_later
end

Looking at the console output, it does not suggest in any way that the devise/mailer/confirmation_instructions.html.haml is ever being rendered.

Any input would be highly appreciated

Forgot to mention current versions I am running on: Devise - 4.2.0, Ruby - ruby 2.2.4p230 (2015-12-16 revision 53155) [x86_64-darwin15], Rails - Rails 5.0.0

Answer 1

Since I was not able to get it working - even after removing all customizations and installing devise from scratch I decided to write my mailers that get fired on sign up, password reset, and invitations - it was more time effective. If anyone ever hits this problem and figures out a more simple and standardized solution - please post!
