Laravel 根据其他集合替换集合值

Question

两个集合：

$users = User::select('id','name')->get();

//outcome  [{"id":"1","name":"John"},{"id":"2","name":"Peter"}]

$orders = Orders::all();

//outcome  [{"id":"1","userid":"1"},{"id":"2","userid":"2"}]

如何修改 $orders 集合“userid”值以替换为真实姓名而不是数字？我想在不修改数据库的情况下将其发送给查看。

$orders 的预期结果：

//outcome  [{"id":"1","userid":"John"},{"id":"2","userid":"Peter"}]

Answer 1

$orders = Orders::with('user')->get();

在您的订单模型中：

public function user(){
return $this->belongsTo(User::class,'userid');
}
