yii2 modal attribute as required dynamically

Question

I have a case where a field is mandatory, but not always mandatory. If I write the attribute as required in modal rules() like: [['my_attribute'], 'required'] then it would make the field required in every case.

can I make a specific modal's attribute as required? in controller's or modal's custom function (i.e the place where I need the field to be mandatory).

P.S: i want to avoid jQuery and JavaScript. Please answer if there is a way in Yii2 to get it done :) thanks.

i have already written my approach above - the rule() required one and the one via jQuery. Do you know any proper way of doing it by yii2 standards? — Danish Ahmed, Apr 08 '16 at 05:14
well its done :) i have overridden the rules() function. Actually i didn't want to do it using scenarios because the work flow in both of my cases are same except 1 attribute. So i was avoiding redundancy. Anyways thanks :) can you please guide me how to close the question? i am new to this. — Danish Ahmed, Apr 08 '16 at 05:37

You could use when from here So, it will be look like that:

public function rules()
{
    return [
        ['password', 'required', 'when' => function($model) {
            return $model->role === 'user'; // boolean should be returned
        }]
    ];
}

It will check the attribute on required condition only when $model s role is user
