Créer un formulaire d'inscription sans FOSUserBundle

Aujourd’hui, nous pouvons facilement nous passer de FOSUserBundle grâce à une vue, un contrôleur, une entité et un formulaire tout simple. De plus, il vous sera beaucoup plus facile de faire des changements dans l’un d’eux si vous en avez besoin
