php - Registering a model as an event listener -



php - Registering a model as an event listener -

i'd know if thought register model class cakeeventlistener within model's php file.

for example, if created model called document implements listener, , @ bottom of document.php there register listener.

class document extends appmodel implements cakeeventlistener { ..... } cakeeventmanager::instance()->attach(classregistery::init('document'));

my question nexted calls classregistery::init('document') , if above cause 2 instances of document created.

for example, let's have next in controller.

class documentscontroller extends appcontroller { public function index() { $model = classregistery::init('document'); .....

how many times document instantiated?

the first phone call classregistery::init('document') controller loads document.php file. wouldn't there sec phone call classregistery::init('document') bottom of document.php befoe first phone call has finished?

would somehow strew registry in cakephp?

it shouldn't problem. classregistry::init() instantiates object once. subsequent calls init() homecoming existing object.

i would, however, suggest registering listener in document's __construct function. feels cleaner because aren't mixing self-executing php class file. allows possible injection later on useful unit tests.
