Manually add item to existing object [Laravel 5]

Question

Here is what I try to do:

$q = Question::where('id',$id -> id)->get();
$q[] = $q->push([ 'test' => true]); 
dd($q);

This will output:

Collection {#220 ▼
  #items: array:3 [▼
    0 => Question {#225 ▶}
    1 => array:1 [▼
      "test" => true
    ]
    2 => null
  ]
}

So 'test' => true will append as a new key, but I want to insert it in Question so latter I can access to it like this with foreach $q -> test

So here is how I want access to item:

@foreach($q as $qq)
{{ $qq->test }}
@endforeach

I don't understan 1 thing: Question::where('id',$id -> id)->get(); why You do not get element by primary key just using: Question::find($id); ? – Haymaker

So funny to get collection of rows when it's always unique (: – Haymaker

If I use find is possible then to add new random attribut? to existing object – Leadsman

of course but, You'll lose ORM functions of it. – Haymaker

Ok,how can I do that? – Leadsman

read answer, updated it – Haymaker

Answer 1

It can be done by using setAttribute() function of Eloquent Model (https://github.com/illuminate/database/blob/master/Eloquent/Model.php).
As You can see it stores data in protected $attributes using setAttribute(), and when we do $SomeModel->some_field it uses magic method __get() to retrieve item by association from attributes array.

Here is the resolution to Your question:

$Question = Question::find($id);
$Question->setAttribute('test', 'blablabla');

It will just create new object, it will not add attribute to my existing object... I taking attrinuts from database: $q = Question::where('id',$id -> id)->get(); and I need on that attributes to add new one. – Leadsman

I am not sure it syntax ok? I get: Cannot pass parameter 1 by reference – Leadsman

It's now better but don't add new item inside attributes it adding on the end of object. any way to fix it? – Leadsman

Try secondary way, by using setAttribute method of Eloquent – Haymaker

@Vladimir Djukic @Haymaker In subsequent loops, how would I push to the array that was set up in the initial loop with setAttribute()? I don't want to overwrite was was already set. – Transmontane

Answer 2

Apart from setAttribute(), you can use put() refer to this post for one item. And map() for many items, refer to this post.

Answer 3

Simply add new attribute like this

$Q = Question::find($id);
$Q->new_attribute = 'data';

In foreach:

foreach($questions as $k=>$q){
   $q->new_attribute = 'data';
   $questions[$k] = $q;
}
