Ruby on Rails: Send Email when Creating a Record Doesn't Work

I'm wondering if someone could help me, within my Ruby on Rails application I am trying to get the system to send an email from a specific email address (Gmail) to a specific email address (Gmail), but for some reason the email does not send - but there is no error message.

Within my controller I have the following code to send an email when a new record is saved:

def create
    @email = Email.new(email_params)
    if @email.save
   UserMailer.welcome_email.deliver
        redirect_to @email
    else
        render 'new'
    end
end

This should call this Mailer:

class UserMailer < ApplicationMailer
  default from: '[email protected]'

  def welcome_email()
     mail(to: '[email protected]', subject: 'Welcome to My Awesome Site')
  end
end

My Application Mailer is as follows:

class ApplicationMailer < ActionMailer::Base
  default from: "[email protected]"
  layout 'mailer'
end

I then have the welcome_email.html.erb:

<!DOCTYPE html>
<html>
  <head>
    <meta content='text/html; charset=UTF-8' http-equiv='Content-Type' />
  </head>
  <body>
    <h1>Welcome to Thor Cinemas,!</h1>
     <p>
      You have successfully signed up to Thor Cinemas,
      your username is: .<br>
    </p>
    <p>
      To login to the site, just follow this link: <%= @url %>.
    </p>
    <p>Thanks for joining and have a great day!</p>
  </body>
</html>

And a similar text version of the above.

For some reason this isn't working, I have the following in $RAILS_ENV (in \config\environments):

config.action_mailer.delivery_method = :sendmail
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
config.action_mailer.default_options = {from: '[email protected]'}

The the below in development.rb of the same location:

Rails.application.configure do
  config.cache_classes = false
  config.eager_load = false
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false
  config.action_mailer.raise_delivery_errors = false
  config.active_support.deprecation = :log
  config.active_record.migration_error = :page_load
  config.assets.debug = true
  config.assets.digest = true    
  config.assets.raise_runtime_errors = true      
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
    address:              'smtp.gmail.com',
    port:                 587,
    domain:               'example.com',
    user_name:            '[email protected]', #replace with your username Eg. john.smith
    password:             'mypassword', #replace with your gmail password
    authentication:       'plain',
    enable_starttls_auto: true  }
end

And the below in production.rb in the same location:

Rails.application.configure do
  config.cache_classes = true
  config.eager_load = true
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true
  config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present?
  config.assets.js_compressor = :uglifier
  config.assets.compile = false
  config.assets.digest = true
  config.log_level = :debug
  config.i18n.fallbacks = true
  config.active_support.deprecation = :notify
  config.log_formatter = ::Logger::Formatter.new
  config.active_record.dump_schema_after_migration = false
  config.action_mailer.delivery_method = :smtp
    config.action_mailer.smtp_settings = {
     :address              => "smtp.gmail.com",
     :port                 => 587,
     :user_name            => ENV['EMAIL_USER'],
     :password             => ENV['EMAIL_PASSWORD'],
     :authentication       => "plain",
    :enable_starttls_auto => true
    }
end

And my Gemfile is as follows:

source 'https://rubygems.org'


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.6'
# Use sqlite3 as the database for Active Record

  gem 'byebug'
end

group :development do

end

gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]
gem 'validates_email_format_of'
gem "letter_opener", :group => :development

What I get in the log when creating a new record is as follows:

I am really confused as to why this isn't working, does anybody know?

Please note that I am using Windows 7 and running Rails 4.2.6.

Mails are not delivered by default in development environment, Add this

      `config.action_mailer.perform_deliveries = true`

in your development.rb to perform deliveries. if you are using Rails 4, use

 Notifier.welcome(User.first).deliver_now

As per the documentation, you can also use

 Notifier.welcome(User.first).deliver_now!

which Delivers an email without checking perform_deliveries and raise_delivery_errors, so use with caution.

Edit:

I see domain missing from your mailer setting in production.rb, use

 :domain               => "gmail.com",

I think you need to use deliver_now instead of deliver.

UserMailer.welcome_email.deliver_now

Hope this will work for you.
