Missing introduction to the validates method in Active Record Validations and Callbacks

Hi all,

It seems that the Active Record Validations and Callbacks guide is missing an introduction to the validates method. It is used for the first time in section 2.4 (http://guides.rubyonrails.org/active_record_validations_callbacks.html#valid-and-invalid) without being defined before. Should I go ahead and add the missing text?

Thanks!

Yes, I think this would be a good idea. Please do it :slight_smile:
