Models, where, when and why?

ok, seriously, don't do that. You might as well not use a framework at all and just do procedural PHP. That's what you're doing anyway.

You are correct when you say that your controllers send the information to your views. But where do they get this information?
They get if from the models. Your models is where all your business logic is placed.

All the interaction with your database(s) is done these. All the processing of your objects and data is done there. The controller should only get the info from there and send it to the views, nothing else.

If you have skinny models and fat controllers you're probably doing it wrong. Your Models should be fat and your controllers skinny. =)
