Kohana 3.3 : required field

Question

I'm using Kohana 3.3. I use ORM for validation form, by determining some rules.

I would like to make a radio button required. I have three options, and no one can be checked in advance.

I've searched on web, no doc.

Someone has an idea ?

Thanks

Just use not_empty rule:

public function rules()
{
        return array(
            'your_field_name' => array(
                array('not_empty'),
            ),
        );
}
