Question

im having troubles with a web app that a teacher ask me to modify, the problem its that i dont know about cakePHP and i have been having troubles.After reading a lot, i think i have grasped the basics of the framework. My problem now its that i have a link in a view so i call a function in the controller to retrive data from the model, the problem its that each time i try to acces the function , the app makes me log in, and the idea its that it shouldnt.
I dont know exactly how the session handling on cakePhp works so, im requesting some help.
the code for the controller its this:

<?php
class RwController extends AppController {
var $name = 'Rw';
// var $paginate = array(
    // 'Tip' => array(
        // 'limit' => 1,
        // 'order' => array(
            // 'tip.created' => 'desc'
        // ),
    // ),
    // 'Evento' => array(
        // 'limit' => 1,
        // 'order' => array(
            // 'evento.fecha' => 'desc'
        // ),
    // )
// );
function map() {
    $this->helpers[]='GoogleMapV3';
}
function pageForPagination($model) {
    $page = 1;
    // $chars = preg_split('/model:/', $this->params['url']['url'], -1, PREG_SPLIT_OFFSET_CAPTURE);
    // #print_r($chars);
    // if(sizeof($chars) > 1 && sizeof($chars) < 3) {
        // #echo "Belongs to ".$model.": \n";
        // #echo var_dump($chars);
    // }
    // $params = Dispatcher::parseParams(Dispatcher::uri());
    // echo "<p>".var_dump($params)."</p><br />";
    #echo $this->params['named']['model'].$model;
    #echo $this->params['named']['page'];
    $sameModel = isset($this->params['named']['model']) && $this->params['named']['model'] == $model;
    $pageInUrl = isset($this->params['named']['page']);
    if ($sameModel && $pageInUrl) {
        $page = $this->params['named']['page'];
    } else {
        #echo var_dump($this->passedArgs);
    }
    $this->passedArgs['page'] = $page;
    return $page;
}

function index() {
    $this->log('indexeando esta chingadera','debug');
    $this->loadModel('User');
    $this->loadModel('Evento');
    $this->loadModel('Tip');

    $dataEvento = $this->Evento->find('all');
    $dataTip = $this->Tip->find('all');

    $page = $this->pageForPagination('Evento');
    $this->paginate['Evento'] = array(
        'contain' => false,
        'order' => array('Evento.fecha' => 'desc'),
        'limit' => 1,
        'page' => $page
    );
    $dataEvento = $this->paginate('Evento');

    $page = $this->pageForPagination('Tip');
    $this->paginate['Tip'] = array(
        'contain' => false,
        'order' => array('Tip.created' => 'desc'),
        'limit' => 1,
        'page' => $page
    );
    $dataTip = $this->paginate('Tip');

    $this->set('users', $this->User->find('all'));
    $this->set('eventos', $dataEvento);
    $this->set('tips', $dataTip);
    $this->set('rw');

    if(isset($this->params['named']['model'])) {
        if (strcmp($this->params['named']['model'], 'Evento') == 0) {
            if($this->RequestHandler->isAjax()) {
                $this->render('/elements/ajax_rw_evento_paginate');
                return;
            }
        } elseif (strcmp($this->params['named']['model'], 'Tip') == 0) {
            if($this->RequestHandler->isAjax()) {
                $this->render('/elements/ajax_rw_tip_paginate');
                return;
            }
        }
    }
}

function about($id = null) {
    $this->Rw->recursive = 0;
    $this->set('rw', $this->paginate());
}

function beforeFilter() {
        parent::beforeFilter(); 
        $this->Auth->allow(array('index', 'about'));
}

function getCentros($id){
    $this->loadModel('Centro');
    $this->log('getcentros','debug');
    if( sizeof($id) > 1){
        $this->set('centros', $this->Centro->query("SELECT centros.id, name, latitud ,longitud 
                                                        FROM `centros`,`centrosmateriales` 
                                                            WHERE centros.id = centro_id 
                                                                AND material_id ='".$id[0]."' 
                                                                    OR material_id='".$id[1]."'"));
    }elseif( sizeof($id) >0) {
        if($id == 0){
            $this->set('centros', $this->Centro->find('all'));
        }else{
            $this->set('centros', $this->Centro->query("SELECT centros.id, name, latitud ,longitud 
                                                            FROM `centros`,`centrosmateriales` 
                                                                WHERE centros.id = centro_id 
                                                                    AND material_id ='".$id[0]."'"));
            }
        }
        $this->redirect(array('action' => 'index'));
}


}   
?>

Edit:

The function im calling is getCentros().

this is what i have in app_controller.

<?php 
class AppController extends Controller {
    var $components = array('Session', 'Auth', 'RequestHandler');
    var $helpers = array('Html', 'Form', 'Time', 'Session', 'Js', 'Paginator', 'GoogleMapV3');
    function beforeFilter() {
        $this->Auth->userModel = 'User';
        $this->Auth->fields = array('username' => 'email', 'password' => 'password');
        $this->Auth->loginAction = array('admin' => false, 'controller' => 'users', 'action' => 'login');
        $this->Auth->loginRedirect = array('controller' => 'users', 'action' => 'index');
    }
}
?> 

Answer 1

try this

$this->Auth->allow(array('*'));

it allows you to access all functions inside the controller.

But before that make sure that you have access on the controller with out errors because your controller name is like this

class RwController extends AppController {

}

may be it want like this

class RwsController extends AppController {

}
