Bonjour,
J'ai une classe User, une classe Artist qui hérite de la classe User, ainsi qu'une classe Media (qui stockent les oeuvres des artistes).
J'extend User pour créer la classe Artist, et je lui rajoute la methode get_newest_media(), que j'appelle dans le __construct, pour récupérer le media le plus récent créé par l'artiste.
