It's a question from Ruby on Rails. There is a table named countries(id, name, code) and it contains records like [{1, India, In}, {2, China, Cn}]. Now if someone wants to do Country.India, it should return the corresponding code of that particular record. In the above mentioned case it will be 'In'. How will you implement it?
