Multipage Forms in Rails

Question

I have a rather complicated model with many fields, associations has_many, images added image_column, etc.

A new object will be added using a multi-page form (8 steps). How can I perform validation and distribution between these steps?

I think it validation_groupcan be useful for determining validations for each step, but what about the overall design?
