Is this an acceptable Ajax action to autoplay CakePHP?

Question

I'm relatively new to CakePHP and wondered how advanced users structure their ajax methods. The purpose of the code is to create a list of compatible JSON products for jQuery autocomplete.

 function autocomplete() {
            $terms = $this->params['url']['q'];
            if (!$this->RequestHandler->isAjax()) {
                $products = $this->Product->find('list', array(
                    'conditions' => array(
                        'Product.name LIKE' => '%'.$terms.'%',
                    ),
                    'limit' => 7,
                    'order' => 'Product.name',
                    'contain' => false
                ));
                exit(json_encode($products));
            } else {
                $this->redirect();
            }
        }

It feels like you just need to throw away exit (), but then again, I don't need to fire any views, am I sure?

Answer 1

Here is what I have done in the past:

In config/routes.phpadd the following:

Router::mapResources(array('restaurants', 'items'));
Router::parseExtensions('json');

In app/app_controller.php:

function beforeFilter() {
    if ($this->isApiCall()) {
        Configure::write('debug', 0);
    }
}

function isApiCall() {
    return $this->RequestHandler->isAjax()
        || $this->RequestHandler->isXml()
        || $this->RequestHandler->prefers('json');
}

app/views/items app/views/restaurants json . .json.

, app/views/layouts/json/default.ctp :

<?php echo $content_for_layout; ?>

---

, http://mydomain.com/items/view.json app/views/items/json/view.ctp, :

<?php echo $javascript->object($item); ?>

$item app/controllers/items_controller.php.

, , , JSON CakePHP.
