body: <p>I have to create a site structure like this<br>

  /demo/admin/create<br>
  /demo/admin/edit/id  </p>
  
  <p>I can create a DemoController which will contains admin. But how to show create/edit pages? The create/edit pages can be accessible only after user is logged in. Where to put create/edit pages?</p>
