Re: Best Practice Question - Components

I would say that calculations, and verification of amounts would be perfect functionality to place on the model.  You wouldn't normally need a controller to determine the sum of items in an order, so why put it in a controller.

For a shopping cart, you still might use a model to store the cart contents and cart items.  You might query the cart to see what the total value is.  This is not a calculation that the controller would need to make, so you wouldn't need to do it in a component either.  All business logic for an entity should stay with the entity, and the model is the perfect place for that.

What you might put in the component is functionality to load a cart that is attached to the session, or clear the cart from the session, if the user requests it, or save cart modifications to the session at the end the controller lifecycle.

Interesting to note, in CakePHP 3.0, the model will be split between an Entity and a Table.  The Table will take care of the schema, and typical database/CRUD operations, while the Entity will concentrate more on the business logic side of things.

Yeah, the point of the exercise is to do things the "Cake Way" and take advantage of all things automagical and Cake. ;) 

After puzzling over the docs for a bit and realizing it's not bad form to have a controller use multiple models, I decided that splitting the existing classes into a model and a component was probably the "correct" solution. The model handles all the data, while the component contains common functions all controllers that use the model will need, like calculations and verification of amounts.
