Ok, I’m trying to have a form that when submitted redirects to a  
preview of the form data,  
with an option to edit, before finally commiting it to the database. I  
know this must involve sessions or cookies, Does anyone know how this  
can be done?

It occurs to me that you could abuse ActiveRecord’s validations for this  
– use a boolean virtual attribute whose presence is validated. It  
won’t be set on the first submission, so the validator will redirect to  
the form, at which point you can set the boolean…
