I have created an article model that works fine. When a user creates
an article and submits the form, I need him/her to be sent to a
preview page to make sure they proofread it. However, I want to use
the model-level validation to validate the input before going to the
preview page. Currently, since the article is only created after the
previewing, there is no validation before the preview. Of course, I
could roll-my-own, but ruby’s is so much easier.
Thanks in advance.
