check for unique on create but not on update

schiefersoft

I have a field in the Editor:

Field::inst('users.username')->validator('Validate::notEmpty')->validator('Validate::unique'),

this works fine when I add a user.
But when I update the user the red error message "This field must have a unique value" comes on the field Username
How can I check the field "users.username" for beeing unique only at the create ?
Thanks

found the solution by my self:

$username = Field::inst('users.username');
if (Editor::action( $_POST ) === Editor::ACTION_CREATE) 
{
    $username->validator('Validate::notEmpty')->validator('Validate::unique');
}
if (Editor::action( $_POST ) === Editor::ACTION_EDIT) 
{
    $username->set(Field::SET_EDIT);
}
