[PROJET] - Restkit mapping

KRM

Bonjour,



Voici ma première question. J'essaie d'afficher des cartes unitaires qui sont liées à  des cartes composites, on pourrait voir cela comme un auteur qui possède x livres et un livre n'a qu'un auteur.



Donc j'essaie de récupérer tous les livres selon l'id de l'auteur.

Cependant, il me fait une erreur et je ne trouve pas pourquoi, si quelqu'un a la gentillesse de m'accorder du temps...



Voici donc tout mes codes se reportant à  cela:

Tu as sans doute déjà  résolu ton problème (il y a d'autres posts).

La prochaine fois, si tu veux obtenir plus de réponse que 0, il suffit d'expliquer l'erreur qui se produit :

• informations relative à  l'erreur -> nous avons des indices
  
• que du code source -> beaucoup de trucs à  lire sans aucun indice -> on passe au post suivant
