Rails - Devise send user email after sign_up/create

Question

I'm fairly new to rails and trying to figure things out. I recently got a mailer all setup and it was working fine. But I am trying to add a second mailer for user actions and it doesnt seem to work.

What I am trying to achieve is that a user signs up, it sends an email to the administrator, then the admin must enable the user. Currently when the admin enables the user it will send them an email, but for some reason my newly created user email does not fire. I think this is because my create method does not fire, where should I put it? Do I need to overwrite a user method?

My UserMailer controller:

class UserMailer < ActionMailer::Base
  default from: "[email protected]"
  def send_enabled_message(user)
    @user = user
    mail(:to => user.email, :subject => "Welcome to Pixel Technologies!!!")
  end
  def send_new_user_message(user)
    @user = user
    mail(:to => '[email protected]', :subject => "New User created please review and enable.")
  end
end

My users_controller:

class UsersController < ApplicationController
  before_filter :authenticate_user!
  load_and_authorize_resource

# POST /users
def create
  @user = User.new(user_params)
  puts "******************** NEW USER ****************************"
  puts user_params
  if @user.save
    puts 'Sending email for create user'
    UserMailer.send_new_user_message(@user).deliver
    redirect_to @user, notice: 'User was successfully created.'
  else
    render action: 'new'
  end
end

But this create method never gets fired. What am I donig wrong. Is there another method I need to put UserMailer.send_new_user_message(@user).deliver?

Answer 1

Confirmation emails should be sent from the controller. It's simple to override the Devise::RegistrationsController defaults.

Create the file app/controllers/my_registrations_controller.rb (name this whatever you want)

class MyRegistrationsController < Devise::RegistrationsController

  def create
    super
    if @user.persisted?
      UserMailer.new_registration(@user).deliver
    end
  end

end

Then in your routes:

devise_for :users, :controllers => { :registrations => "my_registrations" }

When users sign up with Devise, they don't go through the UsersController.

You might want to add the mail sending code in the User model.

For example, in app/models/user.rb:

class User < ActiveRecord::Base
  # ...

  after_create :send_admin_mail
  def send_admin_mail
    UserMailer.send_new_user_message(self).deliver
  end

  # ...
end

This is done by utilizing the Active Record after_create callback.
