title: No Route matches "say/hello" when route exists
body: <p>I'm trying to create a very simple Hello, world program in RoR, but when I go to view the url <code>http://localhost:3000/say/hello</code> I'm getting the error message <code>No route matches: "say/hello"</code></p>
  
  <p>When I started the rails server I got this message with warnings scattered throughout:</p>

  <p>I started with: rails generate controller Say hello goodbye
  which lists route get "say/hello"</p>
  
  <p>Also: I'm having this problem which is probably related. When I go to write some basic html in one of the files that is clearly listed as existing I get this:</p>
  
  <p>I write this:</p>
  
  <pre><code>~/work/demo$ /app/views/say/hello.html.erb
  </code></pre>
  
  <p>Get this error message in return:</p>
  
  <pre><code>bash: /app/views/say/hello.html.erb: No such file or directory
  </code></pre>
  
  <p>What's going on here? I'm getting these instructions straight from Agile Development with Rails and it's so simple. I don't understand what's going on.</p>
