wish of those help I have this Eloquent query: , You should be able to order is ascending something similiar to this:
code :
$events = Product::forCard()->latest()
                            ->take(setting('storefront_recent_products_section_total_products', 10))
                            ->orderBy('start_event', 'asc');

Get Array / List of data for a given field and Use it in Eloquent Query - Laravel

To fix the issue you can do The following code doesn't work, because get() returns a collection of models, not a single model:
code :
Offering::where('user_id', Auth::user()->id)->get()->language;
$languages = Offering::where('user_id', Auth::user()->id)->get()->pluck('language')->toArray();

it helps some times after studying a little bit more, i was able to get it close to what i wanted. i have mounted a sql format for this query, so i able to convert it to eloquent in “raw” format, but i want it in pure eloquent. There are path to that?
code :
$data = \DB::table("jogos")
      ->select("jogos.id", "jogos.titulo", "jogos.qt",  
           \DB::raw("(select 
               sum(case fluxos.tipoacao when 2 then 1 when 1 then -1 end) 
                   from `fluxos` where fluxos.jogo_id=jogos.id) as stock")->get()

To fix the issue you can do Use withCount() and then orderBy() to make it with single query.
code :
ProductCategory::with('categoryProduct')->withCount('categoryProduct')->orderBy('category_product_count','desc')->get();
ProductCategory::withCount('categoryProduct')->orderBy('category_product_count','desc')->get();

will help you I solved this problem:
First off all add a hasOne relation to Product model:
code :
public function latestInventory()
{
    return $this->hasOne(Inventory::class);
}
$products = Product::with(['latestInventory' => function($query) {
    $query->where('count', '>', 0)->orderBy('id');
}]);
$products = $products->get();
$products = $products->sortBy('latestInventory.price')->paginate(16);

return $products->values()->toArray();
Collection::macro('paginate', function($perPage, $total = null, $page = null, $pageName = 'page') {
        $page = $page ?: LengthAwarePaginator::resolveCurrentPage($pageName);
        return new LengthAwarePaginator(
            $this->forPage($page, $perPage),
            $total ?: $this->count(),
            $perPage,
            $page,
            [
                'path' => LengthAwarePaginator::resolveCurrentPath(),
                'pageName' => $pageName,
            ]
        );
    });
<?php

namespace App\Support;
use Illuminate\Pagination\LengthAwarePaginator;
use Illuminate\Support\Collection as BaseCollection;
class Collection extends BaseCollection
{
    public function paginate($perPage, $total = null, $page = null, $pageName = 'page')
    {
        $page = $page ?: LengthAwarePaginator::resolveCurrentPage($pageName);

        return new LengthAwarePaginator(
            $this->forPage($page, $perPage),
            $total ?: $this->count(),
            $perPage,
            $page,
            [
                'path' => LengthAwarePaginator::resolveCurrentPath(),
                'pageName' => $pageName,
            ]
        );
    }
}
