Yii2查询结果总是返回相同的

Question

我正在致力于基于Yii2的项目。今天当我测试我的应用程序时，我注意到了一个非常有趣的错误。我有一个产品表与它的模型和控制器和视图。 （这些是用gii生成的） 当我列出索引操作中的所有记录时，它工作正常。但是这里有bug。当我点击编辑或查看动作时，它会呈现数据库中的第一条记录。我是var_dump查询的结果，并总是返回提到的结果。只有当我使用createCommand时得到了正确的结果。

你认为家伙可能是什么问题呢？

控制器

在index.php视图文件view.php视图文件的

<?php

use yii\grid\GridView; 

/* @var $this yii\web\View */ 
/* @var $dataProvider yii\data\ActiveDataProvider */

Answer 1

尝试修改find​​Model使用功能查找（） - >其中，代替findOne

protected function findModel($id) 
{ 
    var_dump($id); 
    $model = Termek::find()->where(['id'=> $id])->one(); 
    var_dump($model); 
    if (($model !== null) { 
     return $model; 
    } else { 
     throw new NotFoundHttpException('The requested page does not exist.'); 
    } 
} 

Answer 2

我不知道为什么，但不知何故错误解决。我在TermekQuery中有一个函数，它应该查询所有删除字段为空的记录。我删除它，现在工作正常。
