Я пытаюсь перечислить значения из таблицы, которая содержит отношения, созданные в модели, но вместо имени, связанного с этим идентификатором, отображается идентификатор:
District.php и миграция:
<?php

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

/*

public function county()
{
return $this->hasMany('App\Models\County');
}
Миграция:
