Model create does not return id

[SanhDoan]

Hi everyone, I have started used this framework for few weeks and I got an issue that when I use Model::create(), it doesn't auto assign id to my model
For example:

$user = new User();
$user->name = "My name";
$user->create();

echo $user->id; // Result always is "0"

I tried it with raw Phalcon, and got correct id (auto increment) after create

I searched it on google and found this solution, set persistent => true in config/database.php

'mysql' => [
            'host'     => env('DB_HOST', 'localhost'),
            'port'     => env('DB_PORT', 3306),
            'username' => env('DB_USERNAME'),
            'password' => env('DB_PASSWORD'),
            'dbname'   => env('DB_DATABASE', 'slayer'),
            'persistent' => true,
            'charset'  => env('DB_CHARSET', 'utf8'),
            'class'    => Phalcon\Db\Adapter\Pdo\Mysql::class,
        ],

But I think this solution is not the correct approach. Could you please help to show me what I should do?
