VERSION CAKEPHP 2.4.5 I'm working with postgresql 9.1

hello i have this problem, that my login don't work I don't know why? There isn't any error, this is my code that I'm using:

UsersController.php

public function login() {
     
    //if already logged-in, redirect
    if($this->Session->check('Auth.User')){
        $this->redirect(array('action' => 'index'));      
    }
     
    // if we get the post information, try to authenticate
    if ($this->request->is('post')) {
        if ($this->Auth->login()) {
            $this->Session->setFlash(__('Bienvenido, '. $this->Auth->user('username')));
            return $this->redirect($this->Auth->redirectUrl());
        } else {
            $this->Session->setFlash(__('Invalido nombre de usuario o contraseña'));
        }
    }

VIEW login.ctp

App::uses('AuthComponent', 'Controller/Component');

<div class="users form">
<?php echo $this->Session->flash('auth'); ?>
<?php echo $this->Form->create('User'); ?>
    <fieldset>
        <legend><?php echo __('Porfavor ingresa tu nombre de usuario y contraseña'); ?></legend>
        <?php echo $this->Form->input('username', array('label' => 'Nombre de Usuario', 'maxLength' => 60));

<?php echo $this->Form->end(__('Login')); ?>
</div>
<?php
 echo $this->Html->link( "Agregar un nuevo usuario",   array('action'=>'add') ); 
?>

model user.php

 public function beforeSave($options = array()) {
    // hash our password
    if (isset($this->data[$this->alias]['password'])) {
        $this->data[$this->alias]['password'] = AuthComponent::password($this->data[$this->alias]['password']);
    }
     
    // if we get a new password, hash it
    if (isset($this->data[$this->alias]['password_update']) && !empty($this->data[$this->alias]['password_update'])) {
        $this->data[$this->alias]['password'] = AuthComponent::password($this->data[$this->alias]['password_update']);
    }
 
    // fallback to our parent
    return parent::beforeSave($options);
}

AppController.php

class AppController extends Controller {

public $components = array(
    'DebugKit.Toolbar',
    'Session',
    'Auth' => array(
        'loginRedirect' => array('controller' => 'users', 'action' => 'index'),

        'authError' => 'Tu tienes que estas logueado para ver la pagina.',
        'loginError' => 'Invalido nombre de usuario ingresado.'

    ));
// only allow the login controllers only
public function beforeFilter() {
   $this->Auth->allow('login');
}
public function isAuthorized($user) {
    // Here is where we should verify the role and give access based on role   
    return true;
} }
有帮助吗？

ok this the answer FISRT AND IMPORTANT MY VESION OF CAKE PHP IS 2.4.5

I did read: http://book.cakephp.org/2.0/en/core-libraries/components/authentication.html#hashing-passwords

and I after of this I did a lot debugs and I see that my password is not the same that the pasword of mi Database. but this not that simple because i didn't know, how have the same encriptation, and I didn't know what encryptation I was using, so I look for a lot answer here in stackoverflow and this is the best. CakePHP 2.1 Auth->login() not working, but adding user does

the key to all this is here

public function beforeFilter() {
    Security::setHash('sha1');//this is the encryption very important
    $this->Auth->allow('login','add', 'index');
}

now this is my code final:

User.php

 <?php
App::uses('SimplePasswordHasher', 'Controller/Component/Auth');

    public $validate = array(

NOw

login.ctp

<div class="users form">
<?php echo $this->Session->flash('auth'); ?>
<?php echo $this->Form->create('User'); ?>
    <fieldset>
        <legend><?php echo ('Porfavor ingresa tu nombre de usuario y contraseña'); ?></legend>
        <?php 
        echo $this->Form->input('username', array('label' => 'Nombre de Usuario', 'maxLength' => 60));

    </fieldset>
<?php echo $this->Form->end(('Login')); ?>
</div>
<?php
 echo $this->Html->link( "Agregar un nuevo usuario",   array('action'=>'add') ); 
?>

just use imagination for edit.ctp, add.ctp

其他提示

In AppController, add inside Auth (after loginError):

'authenticate' => array('Form')

And in your view, you don't need to import AuthComponent
