如何阅读所有子类别的产品

Question

我需要退货特定类别的产品以及该类别子类别中的以下产品，并且我将laravel多态用于此工作，您能帮我如何退货吗？

我使用递归函数来完成这项工作和这项工作，然后返回给我，但不是最优的

Product.php

/**
 * Get all of the owning product_able models.
 */
public function product_able()
{
    return $this->morphTo();
}

Category.php

/**
 * Get the category's product.
 */
public function product()
{
    return $this->morphOne(Product::class, 'product_able');
}

/**
 * Get all of the categories for the children.
 */
public function children()
{
    return $this->hasMany(self::class, 'parent_id');
}

/**
 * Get the category that owns the parent.
 */
public function parent()
{
    return $this->belongsTo(self::class, 'parent_id');
}

CategoryController.php

public function detail()
{
    $products = new Collection();
    $category = Category::ofUuid(request('category_uuid'))->ofType(config('constants.category.type.main'))->active()->first();

    $products->push($category->product);
    $subCategory = CategoryDetailResource::collection($category->children);
    $products->push(self::check($category));

    $productsFlatten = $products->flatten();
    $productsFilterNull = Utility::filterNullValue($productsFlatten);
    $productsPagination = Utility::paginate_collection($productsFilterNull, 15);
    $productsResource = ProductResource::collection($productsPagination);
    return response()->json([
        'sub_categories' => $subCategory,
        'products' => $productsResource
    ]);
}

public function check($categories)
{
    $data = [];
    foreach ($categories->children as $category) {
        if ($category->product) {
            if ($category->product->status == config('constants.product.status.active'))
                $data[] = [
                    'product' => $category->product,
                    'children' => self::check($category),
                ];
            $data[] = [
                'children' => self::check($category),
            ];
        }
    }
    return $data;
}

CategoryResource.php

/**
 * Transform the resource into an array.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return array
 */
public function toArray($request)
{
    return [
        'uuid' => $this->uuid ?? '',
        'title' => $this->describe->title ?? '',
        'path' => $this->file->path ?? config('constants.default.category.image'),
        'children' => CategoryDetailResource::collection($this->children()->ofType(0)->get() ?? ''),
    ];
}

我的输出：
