I have cars controller, Car model and views for cars.
I am using Twig 1.0,
http://www.twig-project.org/doc/templates.html#list-of-control-structures
Cake 1.3
I want to do the following in the controller:
function index() {
...
$carData = $this->Car->find('all');
$cars = Car::prepareForView($carData);
$this->set('cars', $cars);
}
the prepareForView will turn the car data into an object that
implements the IteratorAggregate
http://php.net/manual/en/class.iteratoraggregate.php
the reason is because i want to be able to do the following in the
view using Twig.
{{ cars.size }} // returns me the size
{{ cars.first }} // returns me the first element of the array
{{ cars.last }} // returns me the last element of the array
Am i right in wanting to prepare the array as an IteratorAggregate?
If i do this for Car and other models, how should i do it?
Advice, please. Thank you.
