How can I customize Devise to send password reset emails using PostMark mailer

Question

I\'m trying to get all of my system\'s email notifications under one umbrella using PostMarkApp and utilizing the Rails gems (postmark-rails, postmark-gem, and mail). I have

Answer 1

Using the latest version of Devise, the methods above didn't help me. This is my solution.

In config/application.rb:

config.action_mailer.delivery_method   = :postmark
config.action_mailer.postmark_settings = { :api_key => "your-API-key-here" }

In config/initializers/devise.rb:

config.mailer = "UserMailer" # UserMailer is my mailer class

In app/mailers/user_mailer.rb:

class UserMailer < ActionMailer::Base
  include Devise::Mailers::Helpers

  default from: "default@mydomain.com"

  def confirmation_instructions(record)
    devise_mail(record, :confirmation_instructions)
  end

  def reset_password_instructions(record)
    devise_mail(record, :reset_password_instructions)
  end

  def unlock_instructions(record)
    devise_mail(record, :unlock_instructions)
  end

  # you can then put any of your own methods here
end

Finally, make sure you have generated custom devise views

rails generate devise:views

and move the email templates from app/views/devise/mailer/ to app/views/user_mailer/

mv app/views/devise/mailer/* app/views/user_mailer/

If you also want to specify 'tags' in postmark headers you have to do this in your mailer:

  # this override method is from Devise::Mailers::Helpers
  def headers_for(action)
    headers = {
      :subject        => translate(devise_mapping, action),
      :from           => mailer_sender(devise_mapping),
      :to             => resource.email,
      :template_path  => template_paths,
      :tag            => action.dasherize # specify the tag here
    }
    if resource.respond_to?(:headers_for)
      headers.merge!(resource.headers_for(action))
    end
    unless headers.key?(:reply_to)
      headers[:reply_to] = headers[:from]
    end
    headers
  end

I also had to generate the views for devise and copy the mail templates into the right place for my mailer. Something like this -

rails generate devise:views
cp app/views/devise/mailer/* app/views/notification_mailer/
