Re: Little trick to return json

I didnt talk about requirements.

It is still good practice. See my post for details on that.

Euromark, you don't need to use .json in the url if the requested response type is set to application/json (As long as you include the RequestHandler component)

You could cut down your code by almost have and drop every second line when following the documentation regarding JsonView:

http://book.cakephp.org/2.0/en/views/json-and-xml-views.html

No need to fight the framework and manually set response type and alike

Also, I highly recommend using /users.json as request url. 
This way you also trigger a lot of Cake magic as well. And you are down to none of your code above, as CakePHP would do all that for you right away.

Sorry for the poor english. 

I created a piece of code that solved my problem in returning a JSON object and helped me not to re-write all views. I await your feedback pros and cons.

 

class AppController extends Controller {
    public $components = array('RequestHandler');

 

    function beforeRender() {
        if ($this->RequestHandler->isAjax()) {
            $this->layout = 'ajax';
            $this->RequestHandler->setContent('json', 'application/json');
            $this->viewVars = json_encode($this->viewVars);
            return false;
        }
    }
}

If an Ajax request is performed automatically be returns a JSON object with the query result.

$.ajax({
url: "http://localhost/aplication/users",
type: "POST",
dataType: "json"
});
