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         


        

Answer 1

For me this "hack" worked best:

instance.errors.add("", "Msg")

When I tried to specify "base" as the first argument, the word base kept getting inserted into my validation messages.
