Zend FR

Bonjour,

Si l'on suit le "Quick Start" de Zend (1.xx), on voit que le Model Mapper est appelé depuis le controller.
J'avais lu l'objection que cet appel n'était pas légitime, le controller ne devant se préoccuper que du Model et pas du Mapper. Qu'en pensent les pros de l'architecture ?

In this example you have exposed the data mapper to the controller but surely the controller should only need to be aware of the model and it's interfaces?

The mapper should handle communication between the model and the database and NOT the controller and the database.

i.e. The code should read:

Code:

    $comment = new Application_Model_Guestbook($form->getValues());
    $comment->save();

INSTEAD OF:

Code:

$comment = new Application_Model_Guestbook($form->getValues());
    $mapper = new Application_Model_GuestbookMapper();
    $mapper->save($comment);

La réponse qui suit me paraît convaincante mais j'aimerais avoir des confirmations

@Karim Yes, you are right about this. But there are a few things that are missed in the tutorial in order to achieve this.

The Application_Model_Guestbook class should have a protected $_mapper property, set and get methods for the mapper.

Code:

public function setMapper($mapper)
{
$this->_mapper = $mapper;
return $this;
}

public function getMapper()
{
if (null === $this->_mapper) {
$this->setMapper(new Application_Model_GuestbookMapper());
}
return $this->_mapper;
}

public function save()
{
$this->getMapper()->save($this);
}

Merci
