Separating Db from business with Inherited classes using multiple views
- by catalinux
I have a software that has a car model that will be used in different views (listing, ads, detail page, carousel, up sell widget,etc).
class CarModel extends DbModel{
}
I look for a "nice way" (a combination of flexible, easy to maintain,etc) to have this used in views.
I'm thinking at two different ways
Having object views for each context
CarViewBase{
var car;// of type CarModel
function constructor(args){
//will instantienta internal variable car based on args
}
function getThumb(){
}
function getTitle(){
}
}
CarListingView extends CarViewBase{
function getListing(){
}
}
CarAdsView extends CarViewBase{
//the busines rule changes for ads widget
function getThumb(){
}
}
Extending directly the CarModel
The challenges comes when My Car Model might need an abstract factory. Let's say I have a field on my car object that states the type of the car : a truck, or a bike, or van. How would affect that my object view? Let's say that getTitle() rule would be different for each type of it.
How would you do it?
