問題描述
這是我嘗試做的:
$q = Question::where('id',$id -> id)->get();
$q[] = $q->push([ 'test' => true]);
dd($q);
這將輸出:
Collection {#220 ▼
#items: array:3 [▼
0 => Question {#225 ?}
1 => array:1 [▼
"test" => true
]
2 => null
]
}
所以 'test' =>true 將作為新鍵追加，但我想將它插入 Question 中，以便以后我可以像這樣使用 foreach $q ->測試
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 $q -> test
所以這是我想要訪問項目的方式:
So here is how I want access to item:
@foreach($q as $qq)
{{ $qq->test }}
@endforeach
推薦答案
可以通過使用 Eloquent Model (https://github.com/illuminate/database/blob/master/Eloquent/Model.php).
如您所見，它使用 setAttribute() 將數據存儲在 protected $attributes 中，當我們執行 $SomeModel->some_field 時，它使用魔術方法__get() 從 attributes 數組中通過關聯檢索項目.
這是您問題的解決方案:
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');
