title: Updating scaffold views after adding new column
body: <p>I created a table using scaffold. Later added a new column</p>
  
  <pre><code>$ rails generate migration add_column_name_to_table_name column_name:string
  $ rake db:migrate
  </code></pre>
  
  <p>Now I'm wondering is there any way to auto-update earlier generated by scaffold views?</p>
