Call, another model in a model

[eluser]chakhar86[/eluser]
From the code I get "my_car" is a class, so you must include or declared above the code?

I recently read a blog about MVC, he said there are two approach to MVC:
1. Thin Controller, Fat Model => Business logic falls to Models
2. Fat Controller, Thin Model => Business Logic falls to Controller

I personally prefer the former. But in case we need a lot of model in single instance of controller then second choice I think have more advantage...

What do you say?
