Well, business logic has to go somewhere. In the MVC pattern, that somewhere is generally the Model tier. The argument for SCFM (as I understand it) is that the controller is a _bad_ place for it.
One thing that took me an embarrassingly long time to get my head around was that the Model layer doesn't have to exclusively be comprised of ActiveRecord-backed classes. You can still use POROs (to borrow a Java term) in your Model tier if that's the best fit for it - don't shoehorn logic into a persistent object if it doesn't really belong there. Ultimately though, there's no magic-bullet, be-all-end-all pattern, as long as: a) It's tested b) It works c) It's comprehensible by you d) It's comprehensible by the person who comes _after_ you If you've got those covered, then you can start bringing in lofty ideals such as DDD. Of course, I might be wrong! - Dan On 23/02/2011, at 7:26 PM, jamesl wrote: > We all know Rails is great and the community is very supportive. > However, there are some practices that leave me a little puzzled/ > bamboozled. > > The Skinny Controller, Fat Model post by Jamis Buck (http:// > weblog.jamisbuck.org/2006/10/18/skinny-controller-fat-model) appears > quite popular.
