title: "No route matches [POST]" when changing link_to to button_to
body: <p>I have this piece of code:</p>
  
  <pre><code>&lt;%= link_to "New User", new_user_path, :class =&gt; "button"  %&gt;&lt;br /&gt;
  </code></pre>
  
  <p>which works fine, but when I change it to,</p>
  
  <pre><code>&lt;%= button_to "New User", new_user_path, :class =&gt; "button"  %&gt;&lt;br /&gt;
  </code></pre>
  
  <p>I get this error</p>
  
  <blockquote>
    <p>No route matches [POST] "/users/new"</p>
  </blockquote>
  
  <p>Any help at all will be appreciated.</p>
