生产服务器上的composer软件包出现问题-Laravel项目

Question

My problem is BadMethodCallException when trait method calls. The package is kalnoy/nestedset for Laravel. On my local server all works perfect, but then I create my app on production server, I always have this exception: Method Illuminate\\Database\\Query\\Builder::descendants does not exist.

What I tried to do without result: 1. composer init 2. composer dump-autoload 3. delete and deployed project few times 4. composer require kalnoy/nestedset 5. Many hours of googling. What thoughts about it? Has anyone had such a problem and sloved it?

My model:

namespace App;

use Illuminate\Database\Eloquent\Model,
    Kalnoy\Nestedset\NodeTrait;

class Category extends Model
{
    use NodeTrait;

    protected $table = 'categories';

    public function getOnMainItems($limit = 6)
    {
        return Category::where('main', 1)->limit($limit)->get();
    }
}

Method what "doesn't exist":

namespace App\Services;

use App\Category;
use Kalnoy\Nestedset\Collection;

class CategoryService
{

    /**
     * @param string $slug
     * @return array $categories
     */
    public function getCatalogCategoriesForFilter(string $slug = '')
    {
        $categories = [];
        if ($slug !== '') {
            $currentCategory = Category::where([['category_slug', $slug], ['active', 1]])->limit(1)->get();
            $categoriesByParent = Category::defaultOrder()->descendantsOf($currentCategory[0]->id);
            foreach ($categoriesByParent as $category) {
                $categories[] = $category->id;
            }
        }
        return $categories;
    }
}

Answer 1

Thanks everyone who helps me. I sloved this.

The problem was in

Category::where('active', 1)->descendants($categoryId);

The Category::where('active', 1) returns queryBuilder object, which has not descendants method, it availabe on Category (model object).

The right way is

Category::descendants($categoryId);

I was embarrassed cause wrong way works on my local server. If somebody can explain this thing I would very grateful.
