laravel - Return Eloquent model with different name from database tables

Question

I want to return a JSON of an Eloquent model, but I'd like to change the array keys. By default they are set as the table field names, but I want to change them.

For example if I have a users table with two fields : id and user_name

When I return User::all(); I'll have a JSON with "[{"id" => 1, "user_name" => "bob}] etc.

I'd like to be able to change user_name to username. I haven't found the way to do it without an ugly foreach loop on the model.

我不确定您为什么首先要这样做，并且如果您的应用程序/最好在整个过程中使事情统一更好，会首先警告您结构。但是如果您真的想这样做..您能做：

$user = User::find($id);
return Response::json(array('id' => $user->id, 'username' => $user->user_name));

这将返回一个包含您想要的 JSON 对象。

您还可以使用以下方法更改密钥的名称：

$arr[$newkey] = $arr[$oldkey];
unset($arr[$oldkey]);

Answer 3

只需将模型的 $hidden 静态设置为要隐藏的键：

类用户扩展 Eloquent { public static $hidden = 'id';

}

并使用 get 和 set 函数以您喜欢的方式命名它们。
