[Rails] Re: only one error message for a field

if the attribute is blank (default is false). http://api.rubyonrails.org/classes/ActiveRecord/Validations/ClassMethods.html#M001639 You will probably want to use allow_blank because if you create an email via params it could come back as an empty string. -- Robert Zotter Zapient, LLC Ruby on Rails
