Отсутствующие данные относятся ко многим

/ 08 мая 2019

Я пытаюсь получить данные от отношений ко многим ко многим, используя Eloquent в Laravel. Каждый раз, когда я делаю это, я получаю ошибку Data Missing.

Я пробовал следующее, чтобы получить данные: 

return  $workers = Worker::first()->workers_sub_categories;

return $workers = Worker::with('workers_sub_categories')->get();

Оба эти результата приводят к ошибке DataMissing.

Модель Worker: 

protected $table = "workers";

protected $primaryKey = 'workers_id';

protected $fillable = [
    'workers_username', 'email', 'password', 'FK_cities_id',
    'FK_packages_id', 'workers_points', 'jwt', 'workers_img',
    'workers_lat', 'workers_lang', 'workers_phone_number',
    'workers_businessregister', 'workers_desc', 'remember_token',
    'workers_status', 'workers_verified', 'step', 'expiry_date', 'workers_created_at', 'workers_updated_at'
];

const CREATED_AT = 'workers_created_at';
const UPDATED_AT = 'workers_updated_at';

public function related_orders()
{
    return $this->hasMany('App\Models\Order', 'FK_workers_id', 'workers_id');
}

public function related_offers()
{
    return $this->hasMany('App\Models\Offer', 'FK_workers_id', 'workers_id');
}

public function related_comments()
{
    return $this->hasMany('App\Models\Comment', 'FK_workers_id', 'workers_id');

}

public function worker_orders()
{
    return $this->belongsToMany('App\Models\Order', 'orders_workers_status', 'FK_workers_id',
        'FK_orders_id')->withPivot('FK_categories_id', 'FK_sub_categories_id');
}

public function related_rates()
{
    return $this->hasMany('App\Models\Rate', 'FK_workers_id', 'workers_id');

}

public function related_city()
{
    return $this->belongsTo('App\Models\City', 'FK_cities_id', 'cities_id');

}

public function workers_sub_categories()
{
    return $this->belongsToMany('App\Models\SubCategory', 'workers_services', 'FK_workers_id',
        'FK_sub_categories_id');
}

public function setWorkersImgAttribute($file)
{
    if ($file) {
        $fileName = $this->createFileName($file);
        $this->originalImage($file, $fileName, 'worker/profile/original');
        $this->mediumImage($file, $fileName, 150, 150, 'worker/profile/meduim');
        $this->thumbImage($file, $fileName, 70, 70, 'worker/profile/thumbnail');
        $this->attributes['workers_img'] = $fileName;
    }
}

public function setWorkersBusinessRegisterAttribute($file)
{
    if ($file) {
        $fileName = $this->createFileName($file);
        $this->originalImage($file, $fileName, 'worker/business/original');
        $this->mediumImage($file, $fileName, 150, 150, 'worker/business/meduim');
        $this->thumbImage($file, $fileName, 70, 70, 'worker/business/thumbnail');
        $this->attributes['workers_businessregister'] = $fileName;
    }
}

Модель SubCategories: 

protected $table = "sub_categories";

protected $primaryKey = 'sub_categories_id';

protected $fillable = [
    'sub_categories_img', 'sub_categories_status', 'FK_categories_id',
];

const CREATED_AT = 'sub_categories_created_at';
const UPDATED_AT = 'sub_categories_updated_at';

public function workers_categories()
{
    return $this->belongsToMany('App\Models\Worker', 'workers_services', 'FK_sub_categories_id', 'FK_workers_id');
}

protected function getArrayableAttributes()
{
    foreach ($this->attributes as $key => $value) {
        if (is_null($value)) {
            $this->attributes[$key] = '';
        }
    }

    return $this->getArrayableItems($this->attributes);
}

public function related_category()
{
    return $this->belongsTo('App\Models\Category', 'FK_categories_id', 'categories_id');
}

public function getSubCategoriesImgAttribute()
{
    return SiteImages_path('subcategory').'/thumbnail/'.$this->attributes['sub_categories_img'];
}

Миграция базы данных: 

$table->bigIncrements('workers_services_id');
$table->bigInteger('FK_workers_id')->unsigned();
$table->bigInteger('FK_sub_categories_id')->unsigned();
$table->foreign('FK_workers_id')->references('workers_id')
    ->on('workers')
    ->onDelete('cascade');
$table->foreign('FK_sub_categories_id')->references('sub_categories_id')
    ->on('sub_categories')
    ->onDelete('cascade');

Предполагается вернуть всех рабочих с опорой.
