Question

当特征方法调用时，我的问题是BadMethodCallException。该软件包是Laravel的kalnoy / nestedset。在我的本地服务器上，所有工作都完美无缺，但是随后我在生产服务器上创建了我的应用程序，总是遇到以下异常：方法Illuminate \ Database \ Query \ Builder :: descendants不存在。

我尝试不做的事情： 1.作曲家 2.作曲家转储自动加载 3.几次删除和部署项目 4.作曲家需要kalnoy / nestedset 5.大量的谷歌搜索。有什么想法吗？有谁遇到过这样的问题并感到高兴吗？

我的模型：

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();
    }
}

计算“不存在”的内容：

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;
    }
}

感谢所有帮助我的人。我很喜欢这个。

问题出在

componentDidMount () {
     const script = document.createElement("script");

     script.src = "https://platform.twitter.com/widgets.js";
     script.async = true;

     document.body.appendChild(script);
}

Category :: where（'active'，1）返回queryBuilder对象，该对象没有后代方法，适用于Category（模型对象）。

正确的方法是

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

我很尴尬，因为在我的本地服务器上无法正常工作。如果有人可以解释这件事，我将不胜感激。
