Well, thank you. I have created some models, refactoring actions from the original controller, and they look and perform well.

Some of them can be reused easily. Others need a level of abstraction that I am not prepared for (by the moment, of course). Moose seems to by the key

So my plan is to move business logic to the model, at least to have it all organized for future refactoring.

I will come back soon. As soon as my Model breaks :-)
