Question

当我尝试使用belongsToMany方法时，只有在连接之后，我才会出现Laravel的奇怪行为。我有这些课程：会议，订单，组织者，用户和产品和这些数据透视表：meeting_organizer，order_product，organizer_user 这是订单类

class Order extends \Eloquent {
public function meeting(){
    return $this->belongsTo('Meeting');
}

public function state(){
    return $this->belongsTo('OrderState', 'order_state_id');
}

public function products(){
    return $this->belongsToMany('Product')->withPivot('qty');
}

public function sellers(){
    $meeting = $this->meeting()->first();
    if($meeting) return $meeting->sellers()->get();
    else return array();
}

public function organizers(){
    $meeting = $this->meeting()->first();
    if($meeting) return $meeting->organizers()->get();
    else return array();
}

当我使用

时

$data['records'] = Order::all();

然后循环：

foreach( $data['records'] as $r ){
        if($r->meeting){
            $r->meeting_date = $r->meeting->date;
            $r->meeting_name = $r->meeting->name;
        }
        $r->status = $r->state->name;
        $r->delivery_date = date_format(date_create($r->delivery_date), 'm-d');

        $r->seller = '';
        foreach( $r->sellers() as $s) $r->seller .= $s->name.', ';

        $r->organizer = '';
        foreach( $r->organizers() as $o) $r->organizer .= $o->name.', ';

        $r->product = '';
        foreach( $r->products as $p) $r->product .= $p->pivot->qty ." x ". $p->name.'<br />';
    }

效果很好。

但如果我使用此连接

$data['records'] = Order
    ::join('meeting_organizer', 'orders.meeting_id', '=', 'meeting_organizer.id')
    ->join('organizer_user', 'meeting_organizer.organizer_id', '=', 'organizer_user.organizer_id')
    ->where('organizer_user.user_id', '=', Auth::user()->id)->get();

循环不返回任何产品。所以，我没有得到任何错误，只是一个空洞的结果。

如果我尝试在我的循环$r->id内的屏幕上打印，结果是错误的并且所有记录的编号都相同，但所有其他属性都是正确的。

Laravel - 加入后无法使用manyToMany方法
