Question

我有一个表单，该表单具有一个paperDOI textInput字段。它必须是唯一的。因此，我遵循以下形式：

<?php $form = ActiveForm::begin(['id' => $model->formName(),'enableAjaxValidation'=>true,'options' => ['enctype' => 'multipart/form-data']]); ?>
<?= $form->field($model->paper, 'paperDOI')->textInput(['maxlength' => true])->label(false) ?>
<?php ActiveForm::end(); ?>

在纸模型规则中，有一个类似[['paperDOI'], 'unique']

的规则

以及在我的控制器中：

 use yii\widgets\ActiveForm;
 public function actionCreate(){
    $model = new PaperMagazine();
    $paper = new Paper();
    $requestPost = Yii::$app->request->post();
    $model->populateRelation('paper', $paper);
    if (Yii::$app->request->isAjax && $model->paper->load($requestPost) && $model->load($requestPost)) {
            Yii::$app->response->format=Response::FORMAT_JSON;
            return ActiveForm::validate($model->paper);
       }
    if ($model->paper->load($requestPost) && $model->load($requestPost))
       {some code for save model...}
}

和actioUpdate：

 public function actionUpdate($id)
    {
        $requestPost = Yii::$app->request->post();
        $model = PaperMagazine::findOne($id);
        if (Yii::$app->request->isAjax && $model->paper->load($requestPost) && $model->load($requestPost)) {
            Yii::$app->response->format=Response::FORMAT_JSON;
            return ActiveForm::validate($model->paper);
        }
        if ($model->load($requestPost) && $model->paper->load($requestPost)) {some codes for save ...}

在create动作中效果很好，并且如果paperDOI已经存在，则会显示验证错误。但以更新形式无效，并发生了奇怪的事件。第一次输入DB中存在的paperDOI时，它显示正确的验证错误。但是只有一次很有效，当我输入另一个代码并离开textInput时，它会抛出错误：

{"name":"PHP Notice","message":"Array to string conversion","code":8,"type":"yii\\base\\ErrorException","file":"D:\\Project Files\\Git\\SAME\\vendor\\yiisoft\\yii2\\db\\ColumnSchema.php","line":157,"stack-trace":["#0 D:\\Project Files\\Git\\SAME\\vendor\\yiisoft\\yii2\\db\\QueryBuilder.php(375): yii\\db\\mysql\\ColumnSchema->dbTypecast()","#1 D:\\Project Files\\Git\\SAME\\vendor\\yiisoft\\yii2\\db\\mysql\\QueryBuilder.php(249): yii\\db\\QueryBuilder->prepareInsertValues()","#2 D:\\Project Files\\Git\\SAME\\vendor\\yiisoft\\yii2\\db\\QueryBuilder.php(345): yii\\db\\mysql\\QueryBuilder->prepareInsertValues()","#3 D:\\Project Files\\Git\\SAME\\vendor\\yiisoft\\yii2\\db\\Command.php(470): yii\\db\\QueryBuilder->insert()","#4 D:\\Project Files\\Git\\SAME\\vendor\\yiisoft\\yii2\\db\\Schema.php(432): yii\\db\\Command->insert()","#5 D:\\Project Files\\Git\\SAME\\vendor\\yiisoft\\yii2\\db\\ActiveRecord.php(549): yii\\db\\Schema->insert()","#6 D:\\Project Files\\Git\\SAME\\vendor\\yiisoft\\yii2\\db\\ActiveRecord.php(515): yii\\db\\ActiveRecord->insertInternal()","#7 D:\\Project Files\\Git\\SAME\\vendor\\yiisoft\\yii2\\db\\BaseActiveRecord.php(670): yii\\db\\ActiveRecord->insert()","#8 D:\\Project Files\\Git\\SAME\\backend\\models\\Log.php(37): yii\\db\\BaseActiveRecord->save()","#9 D:\\Project Files\\Git\\SAME\\common\\OOP\\CommonController.php(124): backend\\models\\Log::Log()","#10 D:\\Project Files\\Git\\SAME\\vendor\\yiisoft\\yii2\\base\\Controller.php(159): common\\OOP\\CommonController->afterAction()","#11 D:\\Project Files\\Git\\SAME\\vendor\\yiisoft\\yii2\\base\\Module.php(528): yii\\base\\Controller->runAction()","#12 D:\\Project Files\\Git\\SAME\\vendor\\yiisoft\\yii2\\web\\Application.php(103): yii\\base\\Module->runAction()","#13 D:\\Project Files\\Git\\SAME\\vendor\\yiisoft\\yii2\\base\\Application.php(386): yii\\web\\Application->handleRequest()","#14 D:\\Project Files\\Git\\SAME\\backend\\web\\index.php(17): yii\\base\\Application->run()","#15 {main}"]}

是什么？为什么在actionCreate上不能正常工作，而在actionUpdate上却不能正常工作？有什么问题吗？

为什么AjaxValidation在yii2的更新形式中不起作用？
