title: Where does business logic go in rails?
body: <p>I'm an ASP.NET MVC developer just starting with my first big project on rails however Im confused as where to put your business logic? on ASP.NET I create a library which contains services(Domain driven design) which handle business logic, I have heard that rails uses a concept of fat model skinny controller but I have some projects in ASP.NET which adding all the logic to the controller would create a big mess, is there any other way?</p>
