Description

JSONAPI::Authorization is a pundit based authorization tool that works out-of-the-box with jsonapi-resources' ActiveRecord backed resources.
The problem is with Cached Resource as it does not have a model key.

JSONAPI::Authorization's related issue https://github.com/venuu/jsonapi-authorization/issues/67

Features:

Exposing the original model into cache in CachedResourceFramgment(https://github.com/cerebris/jsonapi-resources/blob/master/lib/jsonapi/cached_response_fragment.rb#L87) would solve the problem easily – not sure about the cons.

I have a working solution in my fork so I can submit a PR If you are OK with the idea.

Inizia da lib/jsonapi/cached_response_fragment.rb intorno alla riga 87 e verifica come Cached Resource rappresenta attualmente la risorsa. Controlla l’issue collegata di JSONAPI::Authorization e la soluzione del fork riportata, quindi determina se esporre il modello originale risolve la chiave del modello mancante senza effetti indesiderati. Il lavoro è completato quando Cached Resource funziona con il caching delle risorse di JSONAPI::Authorization.
