EDIT: Using own function in validation rules- In the rule specify the function with attribute like this-

array('username','checkuniquename'),

Then define the function logic in same model Like this:

public function checkuniqueemail($attribute)
{
    $record=Users::model()->findByAttributes(array($attribute=>$this->email));
    if($record!==null)
         $this->addError($attribute, 'This email has been already taken please choose a different one');

}

You can define multiple validation rules on single attribute in Yii models.

return array(
                    array('contact_no','numerical', 'integerOnly'=>true),
                    array('contact_no','length', 'min'=>8 ),
                    array('name, contact_no', 'required'),
        array('name, contact_no', 'length', 'max'=>255),
        array('password','pattern'=>'/^[A-Za-z0-9_!@#$%^&*()+=?.,]+$/u', 'message'=>'Spaces or given characters are not allowed'),
    );

There is lot of validation you can specify in your model.
