Laravel 5: how should I implement Auth::admin() as Auth::guest()?

Question

I would like to have administrator authorization. so I have new class in middleware

class Admin {

public function handle($request, Closure $next)
{

    if ( Auth::check() && Auth::user()->isAdmin() )
    {
        return $next($request);
    }

    Session::flash('message', 'You need to be an administrator to visit this page.');

    return redirect('/');

}

}

Then register it in Kernel.php by adding

protected $routeMiddleware = [
    'auth' => \App\Http\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'admin' => \App\Http\Middleware\Admin::class, //added line
];

I also defined isAdmin() in my user model. It works when I do this in the route:

get('protected', ['middleware' => ['auth', 'admin'], function() {
    return "this page requires that you be logged in and an Admin";
}]);

But I want to use it like Auth::admin() as Auth::guest(), where should I implement this function? Do I need a abstract admin() in Guard.php first?

I can get around with Auth::user()->isAdmin(), but I still want to know the right way to do it.

Thanks.

First, you don't need to include both auth and admin middlewares in your route as you already check the authentication within your admin middleware.

get('protected', ['middleware' => ['admin'], function() {
    return "this page requires that you be logged in and an Admin";
}]);

For your question, first, you need to extend the \Illuminate\Auth\Guard and use it instead. Let's say you have a Extensions folder in your app folder.

namespace App\Extensions;

use Illuminate\Auth\Guard;

class CustomGuard extends Guard
{
    public function admin()
    {
        if ($this->user()->isAdmin()) {
            return true;
        }
        return false;
    }
}

Then in your AppService Provider,

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Illuminate\Auth\EloquentUserProvider;
use App\Extensions\CustomGuard;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {  
        Auth::extend('eloquent.admin', function ($app) {
            $model = $app['config']['auth.model'];
            $provider = new EloquentUserProvider($app['hash'], $model);
            return new CustomGuard($provider, \App::make('session.store'));
        });
    }

    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

Finally, in your config/auth.php file, change the line as below.

'driver' => 'eloquent.admin'

Then you should be fine.
