I used Ryan Bates' Railscasts episodes 73-75 to build forms with dynamic added models in complex forms. Everything works great, but displaying validation errors are a big mess since it displays it's own box for each individual error, including an error for each invalid child record in the parent box.
How can I group the errors to display in one box for all the dynamically added models and the main model? I found this solution, but it doesn't really work for dynamically added models and looks super ugly if you try to use it with Ryan Bates style forms:
<%= error_messages_for :every, :single, :model %>
