Question

I have a model where the data is entered over 2 pages. I would like to validate the fields entered on the first page however it isn’t until the second page that the whole model can possibly be valid.

I want to use the standard Rails validation presentation (highlight the fields in error, display the message at the top, reload the page with all the data already in the fields). I would like to avoid coding the validation in the controller.

Has anyone seen a better approach than using the controller, or creating a new “dummy” model with just the data from the first page (which is never saved in the DB).

Thanks!
