Symfony: generating slug url in my article url instead of news id

Question

I would like to have an url like this one:

www.mysite.com/my-super-blog-post

Instead of this one:

www.mysite.com/7

Where '7' is the id property of my News object.

When I see at the Symfony documentation I think I need to use this line of code:

$this->generateUrl('blog_show', array('slug' => 'my-blog-post'), UrlGeneratorInterface::ABSOLUTE_URL);

Is it right ? What I do not understand is where do I need to use that line of code ? In my NewsController.php file ?

Or maybe you can give me a link to read about a solution.

Edit I use Symfony 3.2

Ok I've found the solution by my self. Here it is what I did.

Firstly read this from the symfony doc. Use ConvertParamater It is really easy to implement http://symfony.com/doc/current/best_practices/controllers.html#using-the-paramconverter

After you have implemented it:

Install StofDoctrineExtensionBundle

in composer.json

"require": { "stof/doctrine-extensions-bundle": "~1.1" }

Don't forget to update the appKernel.php file

<?php
// app/AppKernel.php

public function registerBundles()
{
  return array(
    // …
    new Stof\DoctrineExtensionsBundle\StofDoctrineExtensionsBundle(),
    // …
  );
}

Then I configure the config.yml file:

# app/config/config.yml

# Stof\DoctrineExtensionsBundle configuration
stof_doctrine_extensions:
    orm:
        default:
            sluggable: true

Then I add a slug property to my News Entity:

private $slug;

Then I update my News.orm.yml file slug: type: string length: 255 unique: false gedmo: slug: separator: _ style: camel fields: - title

Then I do

doctrine:generate:entites myBundle:News

And also `doctrine:schema:update --force

This created a slug field in my News table. Because this field may not be null, I have manually entered some value so each row of my News table has a valid slug

Then in my NewsController I use this line of code:

$this->generateUrl('myroute_news_show_one_by_id', array('slug' => $news->getSlug()), UrlGeneratorInterface::ABSOLUTE_URL);

        return $this->render('MyBundle:News:single_post.html.twig', [
                    'news' => $news,
                    'tags' => $arrTagNames
        ]);`

And in my Twig template I create link like to show one news:

<a href="{{ path('myroute_show_one_by_id', {'slug': news.slug}) }}">{{news.title}}</a>

I hope this could help someone else

In case anyone is using this old post as a reference for adding slugs to URLs, this functionality is baked into Symfony 4. This post Symfony 4 routing from DB shows how to do it simply using

use Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter;
/**
 * @Route("/page/{slug}")
 * @ParamConverter("page")
 */
public function showAction(Page $page)
{
}

It's working beautifully in my test project. Hope this helps someone!
