[TYPO3-mvc] Models and logic

[Toke Herkild]

Hi all,

Having started using Extbase, I've come to the following question:

Is it possible to add non DB logic to a model ?

Often when doing a MVC project you often got operations which are not 
really DB logic, but still is part of the model and not the controller, 
nor the view, but you need those operations inorder for the view to do 
the right thing.

EG: if you have a larger relational three, and you need a combined state 
of it's completion. you'd have to parse through the different states of 
the model and it's children, and return an array, containing the total 
state.
ex: this->view->assign('state', $TModel->getState());
