Question

I would like to use the devise mailer globally,
since that way I would not have to add another mailer to my app and just use the devise one, to send custom mails outside the devise views/controllers.

Already digged to long for this, anyone know how I can make this possible?

Answer 1

If the point is to only have one mailer, it’s perhaps more straightforward to have your one single mailer just extend the DeviseMailer. E.g. in app/mailer

# app/mailers/mailer.rb
class Mailer < Devise::Mailer

  # add all your custom mailer methods
end

This setup will, for example, cause all emails (from Devise and otherwise) to all be sent with the app/layouts/mailer.html.erb template.

Note that to do this you do need to move the Devise mailer templates from app/views/devise/mailer to just app/views/mailer.
