How to Add to Table from Another Controller Cakephp 3 - cakephp-3.0

Question

I'm new to cakephp3. I would like to know if it is possible to add a new entry form controller1 to table2.
It is a login form. So I would like to authenticate first whether the user is registered, then after authenticating, I would like to save the details to another table.
class UsersController extends AppController
{
public function login()
{
$user = $this->Users->newEntity();
if($this->request->is(['post']))
{
$user = $this->Auth->identify();
if($user)
{
$logs = TableRegistry::get('AttendsTable');
$log->username = 'lorem ipsum';
$log->datenow = '2018-11-10';
$log->tin = '12:42:00';
$log->tout ='12:42:00';
$logs->save($log);
$this->Auth->setUser($user);
$this->redirect(['action'=>'index']);
}
}
}
I am getting an error:
"Argument 1 passed to Cake\ORM\Table::save() must implement interface Cake\Datasource\EntityInterface, instance of stdClass given, called in C:\xampp\htdocs\TimeStamps\src\Controller\UsersController.php on line 32"

Answer 1

Your code isn't working because the Model->save() function expects an entity. In your snippet $log is not defined first, so PHP just makes it a stdClass (gotta love high-level programming :p).
Something like this should work:
$logs = TableRegistry::get('AttendsTable');
$log = $logs->newEntity([
'username' => 'lorem ipsum',
'datenow' => '2018-11-10',
// ...
]);
$logs->save($log);
Moreover, I've heard say it's better to use $this->loadModel() instead of TableRegistry::get():
$this->loadModel('ExternalModel');
// Now available:
$this->ExternalModel->//...
