Cakephp validate data on update entity

Question

I cannot get the validation to work properly when updating entity data. The validation does not work after changing the initial data. The code below provides an example:

    // in controller
    $user = $this->Users->newEntity([
        'mail' => 'wrong',
        'password' => 'password',
        'auth_level' => 0,
    ]);
    debug($user->getErrors()); // Will show error: wrong email format
    $user->mail = "[email protected]";
    debug($user->getErrors()); // Will show no errors
    $user->mail = "wrong";
    debug($user->getErrors()); //Will show no errors

    if (TableRegistry::get('users')->save($user)) {
       // This actually executes
    }

My validation rule in the model is as follows:

public function validationDefault(Validator $validator): Validator
{
    $validator
        ->email('mail')
        ->add('mail', 'unique',
            [
                'on' => ['create', 'update'],
                'rule' => 'validateUnique',
                'provider' => 'table',
                'message' => "Email already in use"
            ]
        );
     return $validator
}

I tried creating rules with "on" => "update", but it does not help.

What I am trying to achieve is to get an entity, change the email address and save it back to database. Upon saving, the email field is neither validated for format nor uniqueness.

The solution is to always update entity data with

$model->patchEntity($entity, $newdata)
