namespace App\Http\Controllers;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Http\Request;

class HomePageController extends Controller
{

public function homepage(){

    $matchThese = [ 'suspended' => 0, 'status' => 1, 'approved' => 1 ];

    $deals = ListsDeals::where( $matchThese )->limit( 3 )->offset( 0 )->orderBy( 'start_date' )->get();

    return view( "homepage" )
            ->with( "deals", $deals );

}

}

我想在HomePageController中查看与交易相同类别的列表，但我不想这样做，我尝试使用withPivot（'list_id'），但我没有获取列表的id，谢谢您的帮助。

请不要只转储所有代码。您应该包含一个。我已经包含了解决方案的相关代码。是的，我已经检查过了，但示例是$user=App\user:：find（1）；foreach（$user->roles as$role）{echo$role->pivot->created_at；}如果找到具有手动编号的用户，我希望在表中找到具有列表id的用户
