Question

我正在使用yii2基本应用。在本地主机上，我的网站运行正常，当我转向另一台计算机时，网站出现问题，登录管理面板后，用户被重定向到.... / breaking-news / index。问题是，在一台计算机（本地主机）上，它运行完美，在另一台计算机（本地主机或互联网上）上工作了一段时间，然后在几小时后尝试测试时，它给了我以下错误登录：

错误

Class＆＃39; app \ controllers \ app \ models \ appModels \ BreakingNewsSearch＆＃39;不   结果

我的控制器是：

搜索模型在这里：... \ mywebsite \ models \ appmodels \ BreakingNewsSearch.php

错误是：找不到类app \ models \ appModels \ BreakingNewsSearch

Answer 1

假设您的use语句正确无误，即

use app\models\appModels\BreakingNewsSearch;

将包含您的BreakingNewsSearch，然后您可以创建没有限定名称的新实例。

/**
 * Lists all AppBreakingNews models.
 * @return mixed
 */
public function actionIndex() {
    $searchModel = new BreakingNewsSearch();
    $dataProvider = $searchModel->search(Yii::$app->request->queryParams);

    return $this->render('index', [
                'searchModel' => $searchModel,
                'dataProvider' => $dataProvider,
    ]);
}

如果yii仍然无法自动加载BreakingNewsSearch类，那么你的路径是错误的;试试

use app\models\appModels\BreakingNewsSearch;

匹配

 use app\models\appmodels\AppBreakingNews;

Answer 2

正如其他人所说，这是模特/ appModels /中的一个问题...... 正确的文件路径是models / appmodels / ... 该错误在Windows上无法观察到，但在ubuntu上导致了上述问题。谢谢你们所有人......

yii2有时找不到搜索模型
