Initialising related models with blank values

Hi all,

I’ve got a given model User that has HAS_ONE relation with the UserProfile entity.

I’m building a new ActiveForm and would like to initialize objects as follows:

$user=new User();


$user->userProfile=new UserProfile();


return $this->render('form,array('user'=>$user));

Yii2 would issue an exception

This is to avoid passing numerous variables to the view, I was thinking about passing the primary model, with all the relations established.

Any ideas on how to overcome this issue?

Solution #1

to inherit ActiveRecord and introduce the following overridden method:

 public  function hasOne($class,$link)




            // this is a new record, no class yet return empty instance

            return new $class;
