この記事参考になる。ネットのrailsのバリデーション情報間違いまくりで全然役に立たない…。- Validations in Rails 3

Another new feature in Rails 3 is the ability to reflect on validations. We can use this if, for example, we want to put an asterisk next to each field in the form that is required. Previously to do this we’d have to install an external plugin so that we could determine which validations were in place for the model on which the form is based (in this case our User model), but now this is included in Rails it’s much easier to add an indicator to each field.
