问题 When Jeremy & Chad posted about their FubuMvc project, one of the differentiators they mentioned was their "Thunderdome Principal": The “Thunderdome Principle” – All Controller methods take in one ViewModel object (or zero objects in some cases) and return a single ViewModel object (one object enters, one object leaves).

问题 Note: I'm a front-end developer wearing a .Net developer's hat for now. Laughable, I know, but how I ended up in this mess is not the point of this question.

问题 In symfony, I see some coders put business logic in the actions ( controllers that is ), and some coders put it in the models ( Doctrine ).
