contact form uninitialized constant contactcontroller

Question

Hello I am trying to implement a contact form following this guide: Contact form in Rails 3

I am not using google apps but 1and1's smtp.

The error I get when I attempt to send the form is

Processing by ContactController#create as HTML
Parameters: {"utf8"=>"✓",       
"authenticity_token"=>"N48ORAhmDqTO7X2wsRlslMJ3l+v=", "message"=>{"name"=>"Patrick", "email"=>"patrick@yahoo.com", "subject"=>"Hello", "body"=>"Hello ME"}, "commit"=>"Send"}

NameError (uninitialized constant ContactController::NotificationsMailer):
app/controllers/contact_controller.rb:11:in `create'

After some attempts at tweaking, I ended up just copying and pasting the code from the guide. Still have a problem.

class ContactController < ApplicationController

def new
 @message = Message.new
end

def create
  @message = Message.new(params[:message])

if @message.valid?
  NotificationsMailer.new_message(@message).deliver
  redirect_to(root_path, :notice => "Message was successfully sent.")
else
  flash.now.alert = "Please fill all fields."
  render :new
end
end

end

NotificationMailer

class NotificationMailer < ActionMailer::Base

 default from: "noreply@misawahousing.com"
 default to: "info@misawahousing.com"

 def new_message(message)
   @message = message
   mail(subject: "[misawahousing.com] #{message.subject}")
   end

end

Answer 1

You have notification_mailer.rb - class NotificationMailer < ActionMailer::Base

change this (remove s)

 NotificationsMailer.new_message(@message).deliver

To

 NotificationMailer.new_message(@message).deliver
