Symfony

Target Symfony3

-Quel outil permet d'installer des bundles dans symfony ?

Composer

-Est-ce dangereux d'utiliser app_dev en prod ? Si oui pourquoi ?
Oui, les erreurs sont affichées en environnement dev, non en prod. l'user ne doit pas voir les erreurs.

-Comment importer le schéma d'une table SQL ?

Symfony 3 : php app/console doctrine:schema:create / update : php app/console doctrine:schema:update
Utilisé --force pour pousser en base, --dump-sql pour visualiser les MAJ

-Quelles sont les différentes étapes à suivre pour passer un site avec Symfony en production ?
0) ./composer install ET php app/console doctrine:schema:create --force ET config.yml
1) Vider le cache de prod : php app/console cach:clear --env=prod
2) Dans web/app.php : setter le second param de new AppKernel à true
3) Vérifier la configuration du serveur : http://symfony.com/doc/current/setup/web_server_configuration.html
En bonus : passer son code au validateur Sensio pour avoir la médaille d'or :)
