使用表单复杂 yii2 保存表单更新时的问题

Question

我有三张表，即家庭（PK id_family 和 FK id_husband）、丈夫（PK id_husband）和房子（PK id_husband）。因为丈夫与房子有关。然后表的丈夫与家庭表相关。

我已经制作了一个更新表格来形成房子以查看下面的参考。在我更新表单时的逻辑之前，表中的一个字段将更新丈夫，在平均字段中，即“status_husband”。因为它已经成功了。 然后，当进程保存在actionUpdate中时，在更新表格房屋上输入时会自动加载家庭表中的字段。 Fieldnya id_family、id_husband 和 status_family。因为它管理得很好，我使用了复合形式的概念。

我想在更新时完成这一切，验证要求表单更新房屋中的所有字段，其中“省”和“城市”必须填写值“example1” ' 全部。所以如果有一个差异将不会被处理。也许有人可以帮助我，谢谢

HouseController 中的代码 actionUpdate

public function actionUpdate($id)
    {
        $house = House::findOne($id);
        if (!$house) {
            throw new NotFoundHttpException("The house was not found.");
        }

        $family = new Family();
        if (!$family) {
            throw new NotFoundHttpException("The family was not found.");
        }

        if ($house->load(Yii::$app->request->post()) && $family->load(Yii::$app->request->post())) {
            $isValid = $house->validate();
            $isValid = $family->validate() && $isValid;
            if ($isValid) {

                // Code for update field status_husband in table Husband
                $husband = Husband::findOne($id);
                $husband->status_husband = 'Meninggal';
                $husband->save();

                // Code for update field in table house
                $house->save(false);

                // Code for insert in table family
                $family->save(false);

                Yii::$app->session->setFlash('success', 'Success!');
                return $this->redirect(['index']);
                return $this->refresh();
            }

如果所有 3 个模型都使用相同的 db 连接组件保存到同一个数据库，则可以使用数据库事务：

public function actionUpdate($id)
{
    $house = House::findOne($id);
    if (!$house) {
        throw new NotFoundHttpException("The house was not found.");
    }

    $family = new Family();
    if (!$family) {
        throw new NotFoundHttpException("The family was not found.");
    }

    $husband = Husband::findOne($id); // Why use the same $id that you use to find $house?
    if (!$husband) {
        throw new NotFoundHttpException("The husband was not found.");
    }

    $post = Yii::$app->request->post();

    // we get the database component used by the House model class and begin a transaction
    $transaction = House::getDb()->beginTransaction();

    try {
        if ($house->load($post) && $family->load($post)) {

            // Try to save $house model
            if(!$house->save()) {
                // If we get a validation error then we will throw an exception and execute the code in catch
                throw new \Exception('House Validation Error');
            }

            // Try to save $family model
            if(!$family->save()) {
                // If we get a validation error then we will throw an exception and execute the code in catch
                throw new \Exception('Family Validation Error');
            }

            // Set new status for $husband
            $husband->status_husband = 'Meninggal';

            // Try to save $husband model
            if(!$husband->save()) {
                // If we get a validation error then we will throw an exception and execute the code in catch
                throw new \Exception('Husband Validation Error');
            }

            // we commit the database changes after every model has been saved succesfully
            $transaction->commit();

            Yii::$app->session->setFlash('success', 'Success!');
            return $this->redirect(['index']);

            // This doesn't get called ever, so why have it here?
            // return $this->refresh();
        } else {
            throw new \Exception('Load Error');
        }
    } catch(\Exception $e) {
        // If we catch any exception we rollback the transaction, reverting all the changes made during the transaction
        $transaction->rollback();
    }

    if (Yii::$app->request->isAjax) {
        return $this->renderAjax('update', [
            'house' => $house,
            'family' => $family]);
    } else {
        return $this->render('update', [
            'house' => $house,
            'family' => $family]);
    }
}
