Значения списка рюкзака Laravel с полем

Я пытаюсь перечислить значения из таблицы, которая содержит отношения, сделанные в модели, но вместо имени, связанного с этим идентификатором, отображается идентификатор:

Как здесь

District.php и миграция:

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Backpack\CRUD\CrudTrait;

class District extends Model
{
use CrudTrait;

/*
|--------------------------------------------------------------------------
| GLOBAL VARIABLES
|--------------------------------------------------------------------------
*/

protected $table = 'districts';
protected $primaryKey = 'id';
// public $timestamps = false;
// protected $guarded = ['id'];
protected $fillable = ['name'];
// protected $hidden = [];
// protected $dates = [];

/*
|--------------------------------------------------------------------------
| FUNCTIONS
|--------------------------------------------------------------------------
*/

/*
|--------------------------------------------------------------------------
| RELATIONS
|--------------------------------------------------------------------------
*/
public function county()
{
return $this->hasMany('App\Models\County');
}

Миграция:`

use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateDistrictsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('districts', function (Blueprint $table) {
$table->increments('id');
$table->string('name')->unique();
$table->timestamps();
});
}

/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop('districts');
}
}`

County.php

    <?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Backpack\CRUD\CrudTrait;

class County extends Model
{
use CrudTrait;

/*
|--------------------------------------------------------------------------
| GLOBAL VARIABLES
|--------------------------------------------------------------------------
*/

protected $table = 'counties';
protected $primaryKey = 'id';
// public $timestamps = false;
// protected $guarded = ['id'];
protected $fillable = ['name', 'DistrictID'];
// protected $hidden = [];
// protected $dates = [];
//$this->table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');

/*
|--------------------------------------------------------------------------
| FUNCTIONS
|--------------------------------------------------------------------------
*/

/*
|--------------------------------------------------------------------------
| RELATIONS
|--------------------------------------------------------------------------
*/
public function district() {
return $this->belongsTo('App\Models\District');
}
}

Миграция:

use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateDistrictsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('districts', function (Blueprint $table) {
$table->increments('id');
$table->string('name')->unique();
$table->timestamps();
});
}

/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop('districts');
}
}

CountyCrudController.php

    <?php

namespace App\Http\Controllers\Admin;

use Backpack\CRUD\app\Http\Controllers\CrudController;

// VALIDATION: change the requests to match your own file names if you need form validation
use App\Http\Requests\CountyRequest as StoreRequest;
use App\Http\Requests\CountyRequest as UpdateRequest;

use App\Models\District as District;

class CountyCrudController extends CrudController
{

public function setUp()
{

/*

$this->crud->setModel('App\Models\County');
$this->crud->setRoute(config('backpack.base.route_prefix') . '/county');
$this->crud->setEntityNameStrings('county', 'counties');

/*
|--------------------------------------------------------------------------

|--------------------------------------------------------------------------
*/

//$this->crud->setFromDb();

// ------ CRUD FIELDS

$this->crud->addColumn([
'name' => 'name', // The db column name
'label' => "County", // Table column heading
'type' => 'text'
]);

$this->crud->addColumn([
'label' => "District", // Table column heading
'type' => "text",
'name' => 'DistrictID', // the column that contains the ID of that connected entity;
'entity' => 'district', // the method that defines the relationship in your Model
'attribute' => "name", // foreign key attribute that is shown to user
'model' => 'App\Models\District' // foreign key model
]);

$this->crud->setColumnDetails('DistrictID', ['attribute' => 'name']);

$this->crud->addField([
'name' => 'name', // The db column name
'label' => "County" // Table column heading
]);

$this->crud->addField([
'label' => 'District', // Label for HTML form field
'type'  => 'select2',  // HTML element which displaying transactions
