title: Help with rails routes
body: <p>I seriously cant understand why this is so hard... I have some experience with other mvc frameworks but always heard rails was the easiest to code in.... right now I cant even get to my controller methods if i want to.</p>
  
  <p>I used scaffold to creat 'student' which automatically created for me the controller, model and views for basic CRUD.. but now I just want to add a method "helloworld" to my controller and when i go to </p>
  
  <pre><code>http://localhost:3000/students/helloworld
  </code></pre>
  
  <p>I get a </p>
  
  <blockquote>
    <p>Couldn't find Student with ID=helloworld</p>
  </blockquote>
  
  <p>error.</p>
  
  <p>what am I missing?..  I know its got to do with routes and the REST thing but I still cant figure out then how else am I supposed to use my own methods... do I have to edit my routes.rb file everytime I create a new method?.. please help</p>
