laravel - 转换 Laravel Eloquent 结果

Question

当我在我的 Controller 中执行它时

$data = User::with('teams')->find(2);
return response(['data' => $data]);

我得到了这个结果

{
        "id": 2,
        "country_id": 1,
        "first_name": "John",
        "last_name": "Doe",
        "created_at": "-0001-11-30 00:00:00",
        "updated_at": "2015-02-02 23:08:21",
        "full_name": "John Doe",
        "teams": [
            {
                "id": 1,
                "name": "Helpdesk medewerker",
                "description": ""
            },
            {
                "id": 2,
                "name": "Retentie",
                "description": ""
            }
        ]
    }

我对完整的 teams 数据不感兴趣，但只对用户的 teamNames 感兴趣。

我是通过添加这个来完成的

$data->each(function($user) {
   $user->team_names = $user->teams->lists('name');
   unset($user->teams);
});

我想知道这是否是修改 Eloquent 结果的正确方法。

您可以使用 attribute accessor为了那个原因。将此添加到您的模型中:

protected $hidden = ['teams']; // hide teams relation in JSON output
protected $appends = ['team_names']; // add custom attribute to JSON output

public function getTeamNamesAttribute(){
    return $this->teams->lists('name');
}

要动态更改hidden 和appends，您可以使用setter 方法:

$data = User::with('teams')->find(2);
$data->setHidden(['teams']);
