What is the Rails3 version of errors.add_to_base?

Question

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

From http://apidock.com/rails/ActiveRecord/Errors/add_to_base:

Use model_instance.errors[:base] << "Msg" instead of deprecated model_instance.errors.add_to_base("Msg") for Rails 3.
