usage of attr_accessor in Rails

Question

When do you use attr_reader/attr_writer/attr_accessor in Rails models?

Answer 1

If you are using it to validate the acceptance of the terms_of_service, you should really consider using validates :terms_of_service, :acceptance => true. It will create a virtual attribute and is much more concise.
