Unable to establish class

[raghava]

Whats wrong with the code. Getting 'Unable to establish class' in the response and data node shows empty instead ?

// Controller code
<?php
class RestsController extends AppController {
    // var $uses = array('User');
    public $components = array (
        'RequestHandler',
        'Rest.Rest' => array(
            'catchredir' => true,
            'actions' => array(
                'extract' => array(
                    'index' => array('users'),
                ),
            ),
            'log' => array(
                'pretty' => true,
            ),
        ),
    );

    public function beforeFilter() {
        $this->Auth->allow('*');
    }

    /**
     * Shortcut so you can check in your Controllers wether
     * REST Component is currently active.
     *
     * Use it in your ->flash() methods
     * to forward errors to REST with e.g. $this->Rest->error()
     *
     * @return boolean
     */
    protected function _isRest() {
        return !empty($this->Rest) && is_object($this->Rest) && $this->Rest->isActive();
    }

    public function index(){
        $users = array(
            array('name' => 'user-1'),
            array('name' => 'user-2'),
            array('name' => 'user-3')
        );
        $this->set(compact('users'));
    }
}
?>

Ratelimiter works on class-basis so you can have different limits for e.g. Employees / Bots / Customers. Supply a class in your auth or do not use ratelimiting

Thanks, I have changed the $components to

    public $components = array (
        'RequestHandler',
        'Rest.Rest' => array(
            'catchredir' => true,
            'actions' => array(
                'extract' => array(
                    'index' => array('users'),
                ),
            ),
            'log' => array(
                'pretty' => true,
            ),
            'ratelimit' => array(
                'enable' => false
            ),
        ),
    );

"Unable to establish class" feedback is not showing up now.

But why I'm not getting the "users" values in the XML from index() action?

[kvz]

unable to determine by this snippet

[raghava]

// routes.php

    // Add an element for each controller that you want to open up
    // in the REST API
    Router::mapResources(array('rests'));

    // Add XML + JSON to your parseExtensions
    Router::parseExtensions('json', 'xml');

Provide also your php/cakePHP versions - so we can setup a similar case

[raghava]

CakePHP version is 2.2.2

I am facing the same problem. The data are not being built in xml.

Cake version: 2.1.0
