Friendlier Error Messages
(from http://apidock.com/rails/ActionView/Helpers/ActiveRecordHelper/error_messages_for#82-Friendlier-error-message-example)

The default error messages can be a bit stale and off putting. Try somethings like this:

 error_messages_for(
   :user,
   :header_message => "Oops - We couldn't save your user!",
   :message => "The following fields were a bit of a problem:",
   :header_tag => :h1
 )

You can also use error_messages_for as follows

 <%  form_for User.new do |f| %>
   <%=  f.error_messages :header_message => "..." %>
 <%  end  %>
