php - Set new attribute to existing object -

i trying add new item object error:

here code:

$q = question::where('id',$id -> id)->first(); $q[]=$q->push('test',5); dd($q); 

here return:

missing argument 2 illuminate\database\eloquent\model::setattribute(), called in /home/client/public_html/storage/framework/compiled.php on line 10231 , defined

any idea how fix this?

according laravel doc,

sometimes may wish save not model, of relationships. so, may use push method

therefore push() try presist attribute , fail because doen't exist in model table. instead of using push(), use dynamic attributes:

$q->randomattribute = "value"; 

i not sure how planning use attribute later, maybe can give better answer.
