Laravel 5.4：在Eloquent中使用groupBy里面的关系whereHas

Question

如何在Eloquent

中的groupBy中使用whereHas

这是我的查询

public function index( Request $request ) {
        $dateFrom = $request->get( 'dateFrom' );
        $dateTo   = $request->get( 'dateTo' );
        $status   = $request->get( 'orderState' );

        $orders = ( new OrderList() )
            ->whereHas( 'orderDetail', function ( $query ) {
                $query->where( 'supplier_id', Auth::guard( 'supplier' )->user()->id );
            } )
            ->when( $dateFrom, function ( $query ) use ( $dateFrom, $dateTo ) {
                $query->whereBetween( 'created_at', [ $dateFrom, $dateTo ] );
            } )
            ->when( $status, function ( $query ) use ( $status ) {
                $query->where( 'order_state_id', $status )->get();
            } )
            ->get();

        //dd( $orders );
        //Order Status
        $orderStates = OrderState::listsTranslations( 'states' )->pluck( 'states', 'id' )->toArray();


        return view( 'supplierComponents.order_list', compact( 'orders', 'orderStates' ) );
    }

我需要按order_id orderDetail中存在的->whereHas( 'orderDetail', function ( $query ) { $query->where( 'supplier_id', Auth::guard( 'supplier' )->user()->id )->groupBy('order_id'); } ) 对订单列表进行分组

我试着这样做

order_id

更新

然后

订单列表详情已groupBy我需要order_list为dd($orders) results

11 => OrderList {#723 ▼ #fillable: array:4 [▶] #connection: "mysql" #table: null #primaryKey: "id" #keyType: "int" +incrementing: true #with: [] #withCount: [] #perPage: 15 +exists: true +wasRecentlyCreated: false #attributes: array:6 [▶] #original: array:6 [▶] #casts: [] #dates: [] #dateFormat: null #appends: [] #events: [] #observables: [] #relations: array:1 [▼ "orderDetail" => Collection {#741 ▼ #items: array:1 [▶] } ] #touches: [] +timestamps: true #hidden: [] #visible: []

#relations: array:1 [▼
            "orderDetail" => Collection {#741 ▼
              #items: array:1 [▶]
            }

看到这个

<!-- ko foreach: AllPens --> <label> <input type="checkbox" data-bind="checked: IsChecked" /> <span data-bind="text: name"></span> </label> <!-- /ko -->

如果它被分组，它应该将相关项目分组到这里，但它会以这种方式发生

但这不起作用，应该采取什么样的正确方法呢？

Answer 1

$orders = ( new OrderList() ) ->whereHas( 'orderDetail', function ( $query ) { $query->where( 'supplier_id', Auth::guard( 'supplier' )->user()->id ); } ) ->with(['orderDetail' => function ($query) { $query->where( 'supplier_id', Auth::guard( 'supplier' )->user()->id )->groupBy('order_id'); }]) ->when( $dateFrom, function ( $query ) use ( $dateFrom, $dateTo ) { $query->whereBetween( 'created_at', [ $dateFrom, $dateTo ] ); } ) ->when( $status, function ( $query ) use ( $status ) { $query->where( 'order_state_id', $status )->get(); } ) ->get(); 不会给你小组，你必须再次得到关系数据。使用以下内容：

{{1}}

Answer 2

$orders = Order::join('orderDetail',function($q){
  $q->on('orderDetail.your_id','orders.id');
  $q->where('supplier_id', Auth::guard('supplier')->user()->id);
})
->select(['orders.user_id','orderDetail.order_id'])
->when($dateFrom, function ( $query ) use ( $dateFrom, $dateTo ) {
  $query->whereBetween('orders.created_at', [ $dateFrom, $dateTo ] );
})
->when($status, function ( $query ) use ( $status ) {
  $query->where( 'orders.order_state_id', $status );
})
->groupBy('orderDetail.order_id')
->get();
