yii2 Search model sometimes not found - php

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

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;

Answer 2

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...
