I am trying to make an Generalization of some classes on my application. I have an "Employee" class that has "number", "name" and "salary" as attributes. I have the "Worker" class and the "Salesman" class that are both Employees and, therefore have all the "Employee" attributes. For example, when creating a new "Worker", I have to put data on my "Employee" class and on my "Worker" class... How do I make this generalization on RoR?
