Laravel Spatie 权限 - 用户和角色关系仅获取 id 和 name

Question

我正在使用 Laravel Spatie 权限来管理我的应用中的角色和权限。我被训练在用户和角色之间的关系中只检索角色 ID 和名称。我的 UserResource 如下所示：

class UserResource extends JsonResource
{
    /**
     * Transform the resource into an array.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function toArray($request)
    {
        return [
            'id'        => $this->id,
            'name'      => $this->name,
            'surname'   => $this->surname,
            'email'     => $this->email,
            'inactive'  => $this->inactive,
            'roles'     => $this->roles
        ];
    }
}

json 看起来像这样：

"data": [
        {
            "id": 1,
            "name": "Admin",
            "surname": "Sudo",
            "email": "admin@sudo.com",
            "inactive": 0,
            "roles": [
                {
                    "id": 1,
                    "name": "Admin",
                    "guard_name": "web",
                    "created_at": "2020-05-28 23:18:58",
                    "updated_at": "2020-05-28 23:18:58",
                    "pivot": {
                        "model_id": 1,
                        "role_id": 1,
                        "model_type": "App\\User"
                    }
                }
            ]
        },
]

我真正需要的是这样的 json：

"data": [
        {
            "id": 1,
            "name": "Admin",
            "surname": "Sudo",
            "email": "admin@sudo.com",
            "inactive": 0,
            "roles": [
                {
                    "id": 1,
                    "name": "Admin",
                },
                {
                    "id": 2,
                    "name": "Default",
                },
                {
                    "id": 3,
                    "name": "Guest",
                }
            ]
        },
]

我真的不知道如何修改我的模型关系或参数 $this->roles（在 UserResources 中）以获得这个 json。

最简单的解决方案是使用地图功能：

'roles'     => $this->roles->map(function($role){
            return [
                'id' => $role['id'],
                'name' => $role['name']
            ];
        })

您可以创建 RoleResource：

class RoleResource extends JsonResource
{
    /**
     * Transform the resource into an array.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
        ];
    }
}

并在您的 UserResource 上使用它：

class UserResource extends JsonResource
{
    /**
     * Transform the resource into an array.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function toArray($request)
    {
        return [
            'id'        => $this->id,
            'name'      => $this->name,
            'surname'   => $this->surname,
            'email'     => $this->email,
            'inactive'  => $this->inactive,
            'roles'     => RoleResource::collection($this->roles),
        ];
    }
}
