access model data in custom validation rule

I have custom validation rule:

public function customRule($check)
{


}

Inside this rule I would like to access some model data (in database). Of course I can do it like this: 

$this->id = 23; 
$this->read();

But then all the data in current model will be overidden by read function (I mean $this->data[$this->alias][...] is overridden.

How I can get this data?

Just to note that if you want to get the full record of the data that is currently being validated it is always accessible in $this->data inside the validation rule as opposed to $check which contains only the data in the currently validated field.

If you need to validate based on something that is stored in the DB, you can use $this->find() or any of the Model's functions as you are in the Model.

I support @burzum 's answer +1.

Use a regular 

$result = $this->find('first', array('conditions' => array($this->alias . '.' . $this->primaryKey => $id));

with the id in the find conditions. And work with the result, it is not overriding the data property.
