I want to write a custom validation in Rails 3, but following this example I get:

'ActiveModel::DeprecatedErrorMethods.add_to_base' call is deprecated in Rails 3.0

What is the rails3 version of:

def validate
   errors.add_to_base "If you are attaching a file you must enter a label for it" if !attachment.blank? and attachment_label.blank?
end

This should work in rails 3.1.3: 

errors.add :base, "message"
