Re: Check Unique in a model

Here's my code:
In class AppModel:

class AppModel extends Model{
function checkUnique($data, $fieldName) {
$valid = false;
if(isset($fieldName) && $this->hasField($fieldName))
{
$valid = $this->isUnique(array($fieldName => $data));
}
return $valid;
}
}

Then for example in the User model:

class User extends AppModel {
var $validate = array(
array('rule'=>array('checkUnique', 'username'), 'message' => 'Username
taken. Please use another one.' )
);
}

It gives the correct behavior for me (check uniqueness when adding,
don't check uniqueness when editing unless the username was changed to
another existing username during edit).
