rails - Devise - Handling - devise_error_messages

in my user edit page, there is a line as follows: <%= devise_error_messages! %> The problem is this does not output errors the standard way that the rest of the app does: <% flash.each do |key, value| %> <div class="flash <%= key %>"><%= value %></div> <% end %> My question is, how do I get the devise error message to work like the others that use the flash.each? Thanks.
