@Nedal Salah,

No, at the moment you are required to use 'id'.

Datamapper follows the design principe that 'id' should be the primary key, integer, and auto_increment. An abstract value, with no meaning within your application. This means you have full freedom to work with your table data without having to deal with major database changes (ever tried to redesign the database where application values are used as foreign keys. A nightmare).
