Symfony Review-2

Doctrine

Symfony does not have core component that works with Databases. Instead, it uses third-party library called Doctrine.
Doctrine allows building database schema through Entity Class, retrieving it, and more.
Symfony commands through bin/console can connect to various functionalities of Doctrine.

Trailing \ Problem

Symfony routing will cause 401 error when there is a trailing slash in the url. To solve it, you should add additional controller for redirections as shown here.

// src/AppBundle/Controller/RedirectingController.php
namespace AppBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;

class RedirectingController extends Controller
{
    public function removeTrailingSlashAction(Request $request)
    {
        $pathInfo = $request->getPathInfo();
        $requestUri = $request->getRequestUri();

        $url = str_replace($pathInfo, rtrim($pathInfo, ' /'), $requestUri);

        return $this->redirect($url, 301);
    }
}
