Example: accepts_nested_attributes_for :tags, :allow_destroy => :true, :reject_if => proc { |attrs| attrs.all? { |k, v| v.blank? } }
:reject_if prevents saving new tags that do not have any attributes filled in. But if in Tag model I use validates contraints it's the same thing? So I can avoid :reject_if. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
