title: How to enable all authenticated routes to show the Devise ajax Login form?
body: <p>I have implemented devise to accept Ajax Login and have created a form to login via ajax which I have put up in a <strong>modal</strong>. However, only when I set up event binders for specific buttons, which trigger the modal ( Such as "<strong>Login now Button</strong>", am I am able to see the form and login. However, I want the modal to appear for any restricted route. ( For example, if I click on : "<strong>Add review</strong>" button, the modal should appear for login( If the user is unauthenticated ). How do I achieve this ?  )</p>
  
  <p>Can I add a specialized class to all the links which require authentication so that I can target them?</p>
