“试图获得非对象的属性”与关系 Yii2

Question

我有这个错误“试图获取非对象的属性”与 Yii2 中的关系（两个表）

$modelSK = SarparastKhanevar::find()->with('tahtTakafols')->where(['code' => $skCode])->all();

在这个 print_r($modelSK) 我有两个表的结果，但我在 print_r($modelSK->tahtTakafols) 中有错误

在 Foreach 中回显结果：

                $i = 0;
                foreach($modelSK as $model)
                {
                    $list[$i]['id'] = $model->id;
                    $list[$i]['code'] = $model->code;
                    $list[$i]['s_id'] = $model->s_id;
                    $list[$i]['u_id'] = $model->u_id;

                    $j = 0;
                    foreach($modelSK->tahtTakafols as $modelTt)
                    {
                        $list[$i][$j]['id'] = $modelTt->id;
                        $list[$i][$j]['sk_id'] = $modelTt->sk_id;
                        $list[$i][$j]['code'] = $modelTt->code;
                        $j++;
                    }
                    $i++;

Answer 1

问题出在这里：

$modelSK->tahtTakafols

你不能像这样访问它，因为这是一个Array of Object。您在两个不同的循环中使用 $model 变量。外循环没问题，但在里面

foreach($modelSK->tahtTakafols as $model)

这条线有问题。

Answer 2

$model->tahtTakafols 不是$modelSK->tahtTakafols
