title: Is Scaffold in rails 3.2 a better option?
body: <p>I am new to ruby on rails.I want to know why do we use scaffold and should we run scaffold directly after the bundle install process.
     I read somewhere that we have to first create controller by doing:-</p>
  
  <pre><code>rails generate controller 
  </code></pre>
  
  <p>and then run the scaffold.
  which one is the preferred method.
  Create the model,controller then use scaffold or run scaffold directly.</p>
