yii2 Search model sometimes not found

Question

I am using yii2 basic app. On local host, my site was running perfect, when I turned to another computer there is a problem with the site, where after login to the admin panel, the user is redirected to ..../breaking-news/index. The problem is that on one computer (local host) it is running perfect, on the other computer (local host or on the internet) it worked perfect for a while then while trying to test after some hours, it gives me the following error after login:

Error

}

The search model is here: ...\mywebsite\models\appmodels\BreakingNewsSearch.php

And the error is : class app\models\appModels\BreakingNewsSearch not found

Answer 1

As the others said, it was a problem in models/appModels/... The correct file path is models/appmodels/... The error was not observable on windows, but on ubuntu it resulted in the mentioned issue. Thanks for all of you...

Answer 2

assuming your use statement is correct, ie

use app\models\appModels\BreakingNewsSearch;

would include your BreakingNewsSearch, then you can create a new instance without the qualified name.

/**
 * 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,
    ]);
}

If yii still can't autoload the BreakingNewsSearch class then your path is wrong; try

use app\models\appModels\BreakingNewsSearch;

to match

 use app\models\appmodels\AppBreakingNews;
