the multiple name issue what you want is a uniqueness validation. hobo has a shortcut when you define the field, you can add :unique => true and it adds a basic validates_uniqueness_of declaration for that field. if you have more complicated uniqueness (i.e. name should be unique for a given product_id but there can be more than one instance of name in the same table), you'll need to use the standard rails validation where you can add scope.
I'm not quite sure what you're asking for the other part of your question. can you perhaps clarify?
