Make Devise error messages appear

Question

In my application.html.erb file, I have

<% flash.each do |key,msg| %>
  <div class="message">
      <%= content_tag :div, msg %>
  </div>
<% end %>

Is there a way to make devise display it's error messages in there?

When I add <%= devise_error_messages! %> <%= devise_error_messages! %> I get a undefined local variable or method 'resource' error.

Just try to put a form_for with url so that devise will be able to check which resource it is referring to..

eg: <%form_for :post,:url=>post_path(@post) do |f|%>
