Question

我有订阅表加入的客户模型和产品模型。当我运行类似的东西 $customers = Customer::with(['products' => function($query) { $query->where('somecondition');}])->get();

如果我像以下客户一样：

    foreach ($customers as $customer){
      foreach($customer->products as $product) {
        # do something
      }
    }

它通过使用动态属性加载客户的整个产品而忽略上述条件。如何解决此问题？

我的课程

class Customer extends Model{

    public function products(){
        return $this->belongsToMany('App\Product', 'subscriptions')->withTimestamps()
    ->withPivot('qty', 'start_date', 'end_date');

    }
}

我在另一个函数中调用它：

           $customers = $request->user()->customers()->where('id', $request['customer_id'])->whereHas(
            'customerstatuses', function ($q) use ($p){
                $q->where('start_date', '<' ,$p)
                    ->where('end_date', '>' ,$p)
                    ->where('active_yn', '=' ,'1');
        })->with(['products'=>  function ($query) use ($p){
                $query->whereHas('productstatuses' ,function ($q) use ($p){
                $q->where('start_date', '<' ,$p)
                ->where('end_date', '>' ,$p)
                ->where('active_yn', '=' ,'1');
                })->wherePivot('start_date', '<', $p )
                    ->wherePivot('end_date', '>', $p)])->get();

你做错了..你应该这样做

factory = sessionmaker()
factory.configure(bind=engine)
session = factory()

关系条件将在$customers = Customer::with(['products' => function($query) { $query->where('somecondition');}]);。

Laravel：循环中不需要时加载动态属性
