Added example for extra key in ApiListener Action

[gringlas]

I thought the documentation could get a bit improved here with an example of how exactly add an extra key to response, as up for today I never really figured it out and even then it took me some trying ;)

Instead of an example using a custom action class, an example which uses $this->Crud->action()->setConfig() would be more suitable.

You mean like, so?

class SomeController extends AppController {

public function initialize() {
      $this->Crud->setConfig([
            'serialize' => [
                'my_extra_data'
            ],
            'api' => [
                'success' => [
                    'data' => [
                        'entity' => [],
                        'my_extra_data'
                    ]
                ]
            ]
        ]);
}

Yes, though you missed the ->action() in the call chain and it should be done in beforeFilter() or controller's action method.

Personnaly, I'm using it like this :

$this->set(compact('aggregation'));
$this->Crud->action()->setConfig('serialize.aggregation', 'aggregation');

Why did those checks fail?
