Description

After upgrading JSONAPI::Resources to version 0.10.2 (coming from 0.9), we noticed the API is causing SQL errors when loading resources from a different database. We have a multi-tenant database, so some resources are fetched from a shared database. It seems this line is causing the syntax to break:
https://github.com/cerebris/jsonapi-resources/blob/master/lib/jsonapi/active_relation_resource.rb#L117

Fetching resources from a different database results in the given query:

SELECT database.table.id AS database.table_id (...)

The dot (.) in the alias is illegal. This results in the following error:

Internal Server Error: Mysql2::Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '.table_id ' at line 1: 

Inizia da lib/jsonapi/active_relation_resource.rb, intorno alla riga 117, e riproduci la query multi-tenant su MySQL utilizzando una risorsa proveniente da un altro database. Esamina l’SQL generato e verifica che gli alias delle colonne risultanti non contengano più punti e che la query abbia esito positivo.
