How to display Flash messages in Rails
Place the following in your ERB view:
<% [:info, :error].each do |key| %>
<% if flash[key] %>
<div class="<%= key %>" id="flash">
<%= flash[key] %>
</div>
<% end %>
<% end %>
or use the following if you prefer Haml:
- [:notice, :error, :success].each do |key|
- unless flash[key].blank?
%p{ :class => "flash #{key}" }= flash[key]
