title: railstutorial ruby on rails Missing template in tutorial
body: <p>I'm in the very beginning of my career as a Ruby on Rails developer
  I'm reading online a book named "Ruby on Rails Tutorial (Rails 5)
  Learn Web Development with Rails"
  I've made an 'hello world' app following the book instructions.</p>
  
  <blockquote>
    <p>app/controllers/application_controller.rb</p>
  </blockquote>
  
  <pre><code>class ApplicationController &lt; ActionController::Base
  
    protect_from_forgery with: :exception
  
    def hello
      render text: "hello world!"
    end
  
  end
  </code></pre>
  
  <blockquote>
    <p>config/routes.rb</p>
  </blockquote>
  
  <pre><code>Rails.application.routes.draw do
  
    root 'application#hello'
  
  end
  </code></pre>
  
  <p>Now I receive that error</p>
  
  <blockquote>
    <p>Missing template application/hello with {:locale=>[:en],
    :formats=>[:html], :variants=>[], :handlers=>[:raw, :erb, :html,</p>
    
    <p>:builder, :ruby, :coffee, :jbuilder]}. Searched in: 
    app_path/app/views</p>
  </blockquote>
  
  <p>I have </p>
  
  <blockquote>
    <p>/app/view/layouts/application.html.erb</p>
  </blockquote>
  
  <p>in my project so that should theoretically be the view, shouldn't it?</p>
  
  <p>So am I missing something?
  How could I fix it? </p>
