错误请求(#400) - 缺少必需参数:YII2中的id

Question

我想使用GII工具进行CRUD操作,但是Missing required parameters: id当我尝试保存帖子时收到错误消息.

邮政控制器:

public function actionCreate()
{
    $model = new Post();

    if ($model->load(Yii::$app->request->post())) {
        $model->post_create_time=date('Y-m-d h:m:s');
        $model->save();
        return $this->redirect(['view', 'id' => $model->id_post]);
    } else {
        return $this->render('create', [
            'model' => $model,
        ]);
    }
}

为什么我总是会收到此错误？

Answer 1

尝试

public function actionCreate()
{
    $model = new Post();

    if ($model->load(Yii::$app->request->post())) {
        $model->post_create_time=date('Y-m-d h:m:s');
        $model->save(false);

        return $this->redirect(['view', 'id' => $model->id_post]);
    } else {
        return $this->render('create', [
            'model' => $model,
        ]);
    }
}

确保你这样做$model->save(false)，看看它是否有效。
