[FIXED] The Auth component still fetching older value of Session?

Issue

I am manually modifying some key of Auth session in beforeFilter of AppController.php by this code

public function beforeFilter(Event $event){
    //$companyId = $this->Companies->find(.........
    $this->request->session()->write('Auth.User.company_id', $companyId);
}

And in various actions of different controller i'm trying to get that stored companyid in session by following way

public function add(){
    $companyId = $this->Auth->user('company_id');
    debug($companyId); die;
}

When i see the value of $companyId, it is showing older value not updated one in beforeFilter method of AppController. However if i refresh the page and donot modify session again i will get updated $companyId value.

So my question is how can i update the value of Auth session data so that i can get updated value with $this->Auth->user('company_id') code in different places in same request?

Solution

The session storage used by the authentication component uses a buffering mechanism, ie the value from the session is usually only read once per request (unless it is being deleted/emptied).

https://github.com/cakephp/cakephp/blob/3.2.8/src/Auth/Storage/SessionStorage.php#L81-L83

So either read the value directly from the session in your controller action, or do not write to the session directly, but to the session storage, something along the lines of

$user = $this->Auth->user();
if (is_array($user) && $user) {
    $user['company_id'] = $companyId;
    $this->Auth->setUser($user);
}
