RouteNotFoundException - Route [login] not defined

[schel4ok]

I posted problem with Class "Admin\MenuItemCrudController" does not exist error, though in my controller namespace was OK.
I am very quickly found that it is because 'namespace' => 'Admin' in routes file.

Route::group([
    'prefix' => config('backpack.base.route_prefix', 'admin'), 
    'middleware' => ['web', 'auth'], 
    'namespace' => 'Admin'], function () {
    // Backpack\MenuCRUD
    Route::crud('menu-item', 'MenuItemCrudController');
});

If replace with 'namespace' => 'App\Http\Controllers\Admin' then this problem disappears, but we have another problem.
When click on menu-item link we have RouteNotFoundException

Symfony\Component\Routing\Exception\RouteNotFoundException - Internal Server Error

Route [login] not defined.

Based on the error you're encountering, the issue is that Laravel's authentication middleware is looking for a route named login, but it's not defined in your application. This is happening because you're using Laravel's default auth middleware, which expects a standard Laravel authentication setup.

According to the Backpack documentation on routes, when working with Backpack's admin panel, you should use Backpack-specific helpers and configurations instead of Laravel's defaults.

Here's how to fix your issue:

Solution

1. Update your route middleware - Instead of using Laravel's default auth middleware, you should use Backpack's middleware configuration. Your routes should look like this:

Route::group([
    'prefix' => config('backpack.base.route_prefix', 'admin'),
    'middleware' => array_merge(
        (array) config('backpack.base.web_middleware', 'web'),
        (array) config('backpack.base.middleware_key', 'admin')
    ),
    'namespace' => 'App\Http\Controllers\Admin'
], function () {
    Route::crud('menu-item', 'MenuItemCrudController');
});

2. Ensure Backpack authentication routes are registered - Make sure you have Backpack's authentication routes set up. These are typically registered in your routes/backpack/custom.php file or through Backpack's service provider.

3. Check your config/backpack/base.php - Verify that your authentication configuration is properly set up, particularly the route_prefix and middleware_key settings.

The key issue is that you're mixing Laravel's standard authentication middleware with Backpack's admin panel. Backpack has its own authentication system and middleware that should be used for admin routes. The auth middleware you're using is trying to redirect to a login route that doesn't exist in your Backpack setup.

If you need to use custom authentication, make sure to define the login route or configure Backpack to use your authentication system properly through the config/backpack/base.php configuration file.

Not agree.

1. During laravel installation I answered NO when asked to install default Laravel's authentication, because I knew I will install backpack later.
2. My routes/backpack/custom.php looks like this

Route::group([
    'prefix' => config('backpack.base.route_prefix', 'admin'), 
    'middleware' => ['web', 'auth'], 
    'namespace' => 'App\Http\Controllers\Admin'], function () {
    // Backpack\MenuCRUD
    Route::crud('menu-item', 'MenuItemCrudController');
});

Route::group([
    'prefix' => config('backpack.base.route_prefix', 'admin'),
    'middleware' => array_merge(
        (array) config('backpack.base.web_middleware', 'web'),
        (array) config('backpack.base.middleware_key', 'admin')
    ),
    'namespace' => 'App\Http\Controllers\Admin',
], function () { // custom admin routes
    Route::crud('user', 'UserCrudController');
}); // this should be the absolute last line of this file

3. In my config/backpack/base.php
   'route_prefix' => 'admin' and 'middleware_key' => 'admin'

[schel4ok]

I changed my route like that

Route::group([
    'prefix' => config('backpack.base.route_prefix', 'admin'), 
    'middleware' => array_merge(
        (array) config('backpack.base.web_middleware', 'web'),
        (array) config('backpack.base.middleware_key', 'admin')
    ),
    'namespace' => 'App\Http\Controllers\Admin'], function () {
    // Backpack\MenuCRUD
    Route::crud('menu-item', 'MenuItemCrudController');
});

Now I have new problem - The model does not exist.

# Exception - Internal Server Error
