How to validate single field of a model in cakephp

问题

I have a model called User and its $validate has 39 field validations and working fine in UsersController. In another controller I need to use the same code and validate only a single field from controller. Can Someonce please help me with this?

Relevant docs.

Use the fieldList option in the model's validates() method.

$this->ModelName->set($this->data);
if ($this->ModelName->validates(array('fieldList' => array('myField')))) {
    // If myField validated successfully...
}
