Suppose I have a model User with two attributes: :name and :age. I want the :age column to be accessible only to "def manipulate_age()"(some method). This also includes, user.update_attributes!(:age => 10) is expected to throw an exception. Is it possible to do that in Rails 3 way?

If you do not list name and age in attr_accessor, you cannot read and write those fields directly.
