I used Ryan B.’ 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 B.  
style forms:

\<%= error\_messages\_for :every, :single, :model %\>
