You must use the "set" method to update an entry. (Again)

Hello everyone,

I'm currently migrating my CI3 project to CI4, but unfortunately I'm struggling with I guess one of the easier things . I already searched the forums and tried some things, but couldn't find a fitting solution. I think my main problem is that the error doesn't really tell me what's wrong and I have no clue what could bring me a step closer to the solution at this point.

In general I only want to create a user in my user model.

This is my Controller Test Case

PHP Code:

public function CreateUserTest()
    {
        $userModel = new UserModel();
        $returnValue = $userModel->create_user('MrXXX', '12345678', 'Max', 'Muster', '[email protected]');
    } 


This is my UserModel declaration and definitions

PHP Code:

protected $DBGroup = 'users';
protected $table = 'user';
protected $allowedFields = ['role_id, first_name, last_name, username, password, '
    . 'email_address, mail_me, ack_round, language, referee, xp, uuid, '
    . 'activation_token, activation, dsgvo, notified']; 


This is my insert statement inside the createuser method

PHP Code:

$this->set('uuid', 'UUID()', false);
    //$this->set('referee', $referee);   
    $data = ['username' => $username,
            'first_name' => $first_name,
            'last_name' => $last_name,
            'email_address' => $email_address,
            'password' => $hash,            
            'activation_token' => $token];
    var_dump($data);
    $insert = $this->insert($data); 


The result from var_dump looks like this:

Code:

array(6) { ["username"]=> string(5) "MrXXX" ["first_name"]=> string(3) "Max" ["last_name"]=> string(6) "Muster" ["email_address"]=> string(15) "[email protected]" ["password"]=> string(60) "CleandUpCleandUp..." ["activation_token"]=> string(254) "CleandUpCleandUp..." }

Thx for your help!
