【问题描述】：

我正在尝试对每个页面进行分页 6 的最大结果。

这是我在控制器中的代码：

public function brand_new(Request $request)
    {
$current_page = $request->get('page', 1);
$find_vehicles = $this->filterAll();//retrieving all the vehicles by calling a method
        $total = $find_vehicles->count();
        $paginator = new LengthAwarePaginator($find_vehicles, $total, 6, $current_page);
        $paginator->setPath($request->getBasePath());
return view('pages.massSearch',compact('paginator'));

这是我在 *.blade.php 中的代码：

    @foreach($paginator->getCollection()->all() as $pg)
   {{ $pg->ImagePath }} {{--ImagePath is the php name of a table column--}}
     @endforeach

但我收到错误：试图获取非对象的属性

任何建议都会有所帮助...

filterAll 方法：

public function filterAll($val)
    {
        $filter_avl = VehicleQuery::create()
            ->filterByAvailability(true)
            ->find();
        $filter_modelAvl = VehicleQuery::create()
            ->useVModelQuery()
            ->filterByAvailability(true)
            ->endUse()
            ->find();
        $filter_bndAvl = VehicleQuery::create()
            ->useVBrandQuery()
            ->filterByAvailability(true)
            ->endUse()
            ->find();

        $filter_cStatus = VehicleQuery::create()
            ->useCurrrentStatusQuery()
            ->endUse()
            ->find();
        $filter_mode = VehicleQuery::create()
            ->useVehicleModeQuery()
            ->filterByModeName($val)
            ->endUse()
            ->find();

        $find_vehicles = VehicleImagesQuery::create()
            ->joinWith('VehicleImages.Vehicle')
            ->joinWith('Vehicle.VModel')
            ->joinWith('Vehicle.VBrand')
            ->joinWith('Vehicle.CurrrentStatus')
            ->joinWith('Vehicle.VehicleMode')
            ->filterByVehicle($filter_avl)
            ->filterByVehicle($filter_modelAvl)
            ->filterByVehicle($filter_bndAvl)
            ->filterByVehicle($filter_cStatus)
            ->filterByVehicle($filter_mode)
            ->find();
        return $find_vehicles;
    }//no errors with this code retrieve data perfectly.. Pagination part is the problem.

【问题讨论】：

请添加有关哪一行导致该错误的信息
使用@foreach($paginator->getCollection() as $pg) 而不是@foreach($paginator->getCollection()->all() as $pg)
我认为是{{$pg->ImagePath }}。如果我编码为 {{ $pg->getImagePath() }} 它会给我错误：调用数组上的成员函数 getImagePath()。
我试过 @foreach($paginator->getCollection() as $pg) 。但是给出了保存错误。
当我尝试 {{ dd($pg) }} 它返回 array:1 [▼ 1790921346 => 0 ]

【解决方案1】：

在这种情况下，我使用 Illuminate\Support\Facades\DB 而不是 propel

$find_vehicles = DB::table('vehicle_images')
            ->join('vehicle', 'vehicle_images.vehicle_id', '=', 'vehicle.id')
            ->join('V_model', function ($join1) {
                $join1->on('vehicle.V_model_id', '=', 'V_model.id')->where('V_model.availability', '=', true);
            })
            ->join('V_brand', function ($join2) {
                $join2->on('vehicle.V_brand_id', '=', 'V_brand.id')->where('V_brand.availability', '=', true);
            })
            ->join('Currrent_status', 'vehicle.Currrent_status_id', '=', 'Currrent_status.id')
            ->join('vehicle_transmission', 'vehicle.vehicle_transmission_id', '=', 'vehicle_transmission.id')
            ->join('vehicle_mode', function ($join3) use($val) {
                $join3->on('vehicle.vehicle_mode_id', '=', 'vehicle_mode.id')->where('vehicle_mode.mode_name', '=',$val);
            })
            ->paginate(6);

如果有人通过 propel 找到解决方法，请发布答案..无论如何谢谢你们，感谢您的帮助...
