Title: Solving Laravel 8 Auth Route [login] Not Defined Error for User Login and Restrictions
Body:
As a newbie to Laravel, you have been trying to create your own login system but have encountered some difficulties. The error 'Route [login] not defined' is preventing the user from accessing other pages while retaining their identity. In this comprehensive guide, we will walk you through the process of creating a login system and applying user restrictions on various pages in Laravel 8.
Firstly, let us take a look at your code snippets:
1. web.php - Here you have defined your routes for login and student/home. Your intended login route is set to 'login'.
2. userLoginController.php - This controller handles the login process by authenticating the student data using their email address and password. An issue with this code could be that the redirect statement might be incorrectly referring to the 'student.home' route, which is not defined yet.
3. auth.php - Your configuration file contains multiple guards for different user types under the guards section, including web, students, and api. This setup is fine as long as you have properly configured your login process for each guard.
4. Models - You have defined two models, one for users and another for students. They appear to be correctly set up.
To fix this issue, begin by defining the login route in web.php:
```php
Route::post('login', [UserLoginController::class, 'loginPost'])->name('login');
```
Next, update your userLoginController.php with the following code to handle the authentication process and redirect properly based on the guard:
```php
public function loginPost(Request $request)
{
if (auth()->attempt(['email' => $request->student_mail, 'password' => $request->student_password], false)) {
return redirect()->intended('student/home');
} else {
echo "yannlış";
}
}
```
Note that we have changed the middleware configuration in your web.php file to correctly use the students guard for '/' route, ensuring the login page loads correctly:
```php
Route::get('/', function () {
return view('login');
})->middleware('auth:students');
```
To enable user restrictions on other pages, add middleware configuration to your web.php file:
```php
Route::get('student/home', [StudentHomeController::class, 'index'])->name('student.home')->middleware('auth:students');
Route::group(['middleware' => ['auth']], function () {
// Other protected routes will go here
});
```
After fixing these changes, test your login functionality and ensure it redirects to the correct page. If you continue experiencing issues, review the Laravel documentation for further guidance on authentication and middleware configurations.

With this corrected code, you should be able to properly manage user logins and restrictions in your Laravel application.
