cakephp 3 using for login another model than users auth - mysql

Question

I'm trying to make a login from another model and I have an error.
This is my code for Student Model
var $name= 'Student';
public $components = array(
'Session',
'Auth' => array(
'loginAction' => array(
'controller' => 'students',
'action' => 'login',
'plugin' => 'students'
),
'authError' => 'Did you really think you are allowed to see that?',
'authenticate' => array(
'Form' => array(
'fields' => array(
'username' => 'username', //Default is 'username' in the userModel
'password' => 'password' //Default is 'password' in the userModel
)
)
)
)
);
StudentsController looks like
public function beforeFilter(Event $event) {
parent::beforeFilter($event);
$this->Auth->allow('login');
}
public function login() {
if($this->Session->check('Auth.Student')){
$this->redirect(array('action' => 'login'));
}
if ($this->request->is('post')) {
if ($this->Auth->login()) {
$this->Session->setFlash(__('Welcome, '. $this->Auth->student('username')));
$this->redirect($this->Auth->redirectUrl());
} else {
$this->Session->setFlash(__('Invalid username or password'));
}
}
}
And the AppController is
public function initialize()
{
parent::initialize();
$this->loadComponent('RequestHandler');
$this->loadComponent('Flash');
}
public $components = array(
'Session',
'Auth' => array(
'loginRedirect' => array('controller' => 'students', 'action' => 'login'),
'loginAction' => array('controller' => 'students', 'action' => 'login'),
));
public function beforeFilter(Event $event) {
$this->Auth->authenticate=array (
'loginAction' => [
'controller' => 'Students',
'action' => 'login',
'plugin' => false,
],
'Basic' => ['userModel' => 'Students'],
'Form' => ['userModel' => 'Students']
);
}
And I have the following error
Component class SessionComponent could not be found.
How can I fix it?

Answer 1

Session was deprecated in cakePHP 3, How you are doing is for cake2. In cake 3 you can use RequestHandeler like,
$this->loadComponent('RequestHandler');
OR
public $components = array(
'RequestHandler'
);
then use,
$this->request->Session()->read/write/delete/destroy();
Hope this will work for you :).
