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)

Re: Little trick to return json

2014-01-23 Thread Dakota

A far better, more scalable way of doing it (That is actually built into 
the framework):

*routes.php*

> Router::parseExtensions();

Router::setExtensions(array('json', 'xml'));

 
*AppController.php*

> class AppController extends Controller {

public $components = array('RequestHandler');

} 


*Any controller action that you want to JSONify:*

> public function index() {

$this->set('myData', $myData); 

$this->set('_serialize', 'myData');

} 


*Or, to match your original intentions, in AppController.php*

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

function beforeRender() {

   $this->set('_serialize', array_keys($this->viewVars));
> }
> }


And then to make a request:

> $.ajax({
> url: "http://localhost/aplication/users";,
> type: "POST",
> dataType: "*json*" //or *xml* if you want xml data
> });

Re: Little trick to return json

2014-01-22 Thread euromark

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.

Subject: Little trick to return json

 

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"
});
