how get ID from model->create()

has not found in documentation how get ID record after add it in table

that on similar

function id(){ return mysqli_insert_id($this->conect); }

in

$user = new Users();
$user->password = 'pass';
$user->name = 'user';

if ($user->create())
{
    $id = $user->id(); // ????? how ????
}

You can get it from the connection object like this:

$result = $user->create(); 
if ($result) {
    $id = $user->getConnection()->lastInsertId(); 
}

If the field 'id' is auto_increment you can automatically get the generated value by just accessing the property after saving:

if ($robot->save()) {
    echo "The robot id is", $robot->id, '<br>';
}

Hi, I have a problem getting the last id of a related table. if I use $ variation-> id; it brings me null and if I use $ variation-> theInsertId (); I get an error with foreign key problems

Can you get the last id after a save within a try catch?
