Nouvelle API pour gérer les contenus

[artragis]

le but de cette PR est de créer une API pour gérer les tutos (pour l'instant, on ne joue pas pour l'affichage des publications).

Cela peut être vu comme le pendant backend de la nouvelle interface de rédaction qui est en cours de maquettage.

Je vais faire deux endpoints ou groupe de endpoints :

• Gestion des chapitre/extraits/parties.
• Gestion des métadata (titre, licence, catégorie...)

Ça serait bien que j'ai un petit descriptif de ce que je dois mettre dans ces endpoints pour correspondre aux besoins du frontend

QA

• Review
• si vous voyez des cas qui ne sont pas testés dans test_api.py dites-le je les ajoute.

[artragis]

Quelqu'un pour faire la QA svp?

[Situphen]

Je l'ai déployée sur la bêta mais j'ai 2 erreurs 500 sur /api.
