title: Rails: Scaffold to automatically do one-to-many relationship
body: <p>Not sure if I'm reading <a href="https://stackoverflow.com/questions/163797">this</a> right, but it seems like Scaffold will not do a one-to-many relationship in its entirety. For instance, if I create <code>messages</code> with scaffold and then I want <code>comments</code> on those <code>messages</code> (one <code>message</code> -> many <code>comments</code>), I have to go through and change everything. For instance, I have to change this in the <code>comment</code>'s <code>new</code> view</p>
  
  <pre><code>&lt;% form_for(@comment) do |f| %&gt;
  </code></pre>
  
  <p>to this</p>
  
  <pre><code>&lt;% form_for([@message, @comment]) do |f| %&gt;
  </code></pre>
  
  <p>and then change the Action to set up the <code>@message</code> var... amongst other things.</p>
  
  <p><strong>This cannot currently be done automatically with Scaffold, right?</strong></p>
