title: NameError in UsersController#show
body: <p>I am currently working on the Ruby on Rails tutorial by Michael Hartl. I am trying to add a page for each user in my database by creating an HTML with embedded ruby page in the views directory. The code for show.html.erb is below:</p>
  
  <pre><code>    &lt;%= @user.name %&gt;, &lt;%= @user.email %&gt;
  </code></pre>
  
  <p>When I add the user to the user_controller.rb file, it looks like this:</p>
  
  <pre><code>class UsersController &lt; ApplicationController
      def show
         @user = User.find(params[:id])
      end
  
      def new
      end
    end
  </code></pre>
  
  <p>When I run the rails server and click on open up the users/1 URL, I get a NameError complaining about an uninitialized constant. The error and trace is below:</p>
  
  <pre><code>NameError in UsersController#show
  uninitialized constant UsersController::User
  
  Rails.root: /usr/sample_app

  <p>Please let me know how to go about this because I cannot pass my spec tests with this error.  If anyone has any suggestions or insight I would greatly appreciate them.Thank you.</p>
