Partial Validation of Active Record Objects
Ever want to save, just part of an object? You can with partial validation. This example uses Wicked a gem for making step by step wizards, and shows you how to build objects piece by piece and validate every step of the way

Interesting. I wonder if this could be combined with a state machine in a model, as described in this very insightful post: http://lucapette.com/rails/grouping-validations/
Especially the validate block syntax mentioned in the comments there could be used in the examples, i guess.
