Chapter 11, Iteration F2: Flash notice not displayed

Working along with the Logging In paragraph 11.2, I noticed that the flash notice wasn’t displayed when I used a non-existing username:

flash.now[:notice] = "Invalid username/password combination" 

After some investigation, that makes sense, because the login.html.erb doesn’t contain any code to display such a message. So I duplicated the code from store.html.erb:

<% if flash[:notice] -%>
   <div id="notice"><%= flash[:notice] %></div>
<% end -%>

update
,which of course isn’t needed anymore after implementing iteration F4, where the store layout (including the flash display code) is applied generally :-)
