Laravel Eloquent - pluck() 角色名称

Question

I'm trying to get the authenticated user object from the request with roles. I'm using Spatie and Laravel 8.

Getting User object from request like so

$request->user()->getRoleNames()->pluck('name');
return $request->user();

Returns

{
   "id":1,
   "name":"User name",
   "email":"User email",
   "email_verified_at":null,
   "company":"--",
   "phone":"--",
   "created_at":"--",
   "updated_at":"--",
   "roles":[
      {
         "id":1,
         "name":"Super Admin",
         "guard_name":"web",
         "created_at":"--",
         "updated_at":"--",
         "pivot":{
            "model_id":1,
            "role_id":1,
            "model_type":"App\\Models\\User"
         }
      }
   ]
}

What I need to be returned

{
   "id":1,
   "name":"User name",
   "email":"User email",
   "email_verified_at":null,
   "company":"--",
   "phone":"--",
   "created_at":"--",
   "updated_at":"--",
   "roles":["Super Admin"]
}

Note:

I don't understand why adding $request->user()->getRoleNames()->pluck('name'); makes the roles appear. Without it, the roles don't appear at all. I assumed I would need to do $request->user()->with('roles'); but that doesn't work (returns null ).

Answer 1

False alarm. Think I was just overthinking it.

Added roles to user object, like so

$user = $request->user();
$user->roles = $user->roles()->pluck('name');
return $user;

Answer 2

Another alternative is using hidden , appends and an accessor, like getRoleNamesAttribute() :

class User extends Model {
  ...

  // This will hide `roles` from your `User`, when converted to JSON/Array/etc
  protected $hidden = ['roles'];

  // This will add `role_names` to your `User`, when converted to JSON/Array/etc
  protected $appends = ['role_names'];

  // Accessible via `$user->role_names`, or `user.role_names` in JSON
  public function getRoleNamesAttribute() {
    return $this->roles->pluck('name'); 
  }

  ... // Everything else
}

Doing this, in conjunction with return $request->user(); will automatically make roles invisible, and appends role_names . In your code, you should get the output:

{
   "id":1,
   "name":"User name",
   "email":"User email",
   "email_verified_at":null,
   "company":"--",
   "phone":"--",
   "created_at":"--",
   "updated_at":"--",
   "role_names":["Super Admin"]
}

你也可以这样做：

$user->roles = User::find($user->id)->getRoleNames();
