explanation about filterPaginateOrder trait

[t0n1zz]

hi, i love your project and it works very well and match what i need for an spa project with laravel. But i don't quite get it how everything works... and now i having a hard time to using it with json data that returned like this

{
  "model": {
    "current_page": 1,
    "data": [
      {
        "id": 8,
        "id_cu": 0,
        "id_pus": 1,
        "name": "test1",
        "username": "test17",
        "gambar": "",
        "status": 1,
        "created_at": "2018-02-27 06:37:10",
        "c_u": null,
        "pus": {
          "id": 1,
          "name": "Puskopdit BKCU Kalimantan"
        },
        "roles": [
          {
            "name": "CU Akses Penuh",
            "pivot": {
              "model_id": 8,
              "role_id": 2
            }
          }
        ]
      },
      {
        "id": 7,
        "id_cu": 0,
        "id_pus": 1,
        "name": "test1",
        "username": "test16",
        "gambar": "",
        "status": 1,
        "created_at": "2018-02-27 06:36:06",
        "c_u": null,
        "pus": {
          "id": 1,
          "name": "Puskopdit BKCU Kalimantan"
        },
        "roles": [
          
        ]
      }
    ],
    "from": 1,
    "last_page": 4,
    "next_page_url": "https://bkcuvue.dev/api/v1/user?page=2",
    "path": "https://bkcuvue.dev/api/v1/user",
    "per_page": "2",
    "prev_page_url": null,
    "to": 2,
    "total": 8
  }
}

so according to the json data returned above i want to user roles for search_column, i tried to use roles.name but it is not working so any idea to use those?

my controller is like this

public function index()
	{
    	$table_data = User::with(array('CU','pus','roles' => function($query){
				$query->select('name');
			}))->select('id','id_cu','id_pus','name','username','gambar','status','created_at')->filterPaginateOrder();

    	return response()
			->json([
				'model' => $table_data
			]);
	}

I think u have to use WhereHas method

[t0n1zz]

whereHas? care to explain more? i'm still not really understand about whole eloquent and collection thing works in laravel...

and for more information roles table is from spatie permission package and i just happen to find out i can get those related roles to the user model by using with like that

[anishdcruz]

In order to filter the results by relationship you have to use whereHas method.

For example:

User::with(['a', 'b', 'etc'])
  ->whereHas('roles', function($query) {
    $query->where('name', '=', 'admin'); // any search function
})->get();

The above code is not tested.

hmm but i'm in situation where i don't know which roles name will be, in fact i trying to get those roles name. so i am calling user model and roles that have relation with those user model.... i trying to make a list of table with user model (name, username, etc) with roles that those user model have.
