namespace App\Http\Controllers\Boot;

use App\Http\Requests\StoreArticle;
use App\Models\Article;
use App\Models\ArticleCategory;
use Illuminate\Http\Request;
use Mockery\Exception;

class ArticleController extends CommonController
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index($recover = false, $type = null, $order = null)
    {
        //default article list
        $articles = Article:: with('category')->orderBy('created_at','desc')->paginate(10);

        //if is recover list
        if ($recover == true){
            //count attribute and order
            if ($type !== null && $order !== null){
                $articles = Article::onlyTrashed()->orderBy($type,$order)->paginate(10);
            }else{
                $articles = Article::onlyTrashed()->orderBy('created_at','desc')->paginate(10);
            }

        }else{
            //count attribute and order
            if ($type !== null && $order !== null){
                $articles = Article::with('category')->orderBy($type,$order)->paginate(10);
            }
        }

       return view('boot.article.index', [
           'articles'   => $articles,
           'recover'    => $recover,
           'order'      => $order,
           'type'       => $type,
           ]);
    }

}
