Version 0.10.5

#<ActiveRecord::StatementInvalid: 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 '."id" AS "individuals_id", individuals.id FROM `individuals` WHERE `individuals`' at line 1: SELECT  "individuals"."id" AS "individuals_id", individuals.id FROM `individuals` WHERE `individuals`.`deleted_at` IS NULL ORDER BY individuals.id asc LIMIT 10 OFFSET 0>
>> fragments = resource_klass.find_fragments(find_options[:filters], options)

This is related to #1310, but is not a multi-tenancy issue. This a MySQL syntax issue that I believe it created by the ActiveRelationResource#quote method which is uses explicit double quotes for quoting table names in ActiveRelationResource#concat_table_field and ActiveRelationResource#alias_table_field.

By adding MySQL to the CI workflow testing matrix, this issue is easily reproduced in CI testing. I will create a PR for adding MySQL to the testing matrix.

Empieza leyendo quote, concat_table_field y alias_table_field en lib/jsonapi/active_relation_resource.rb, y luego reproduce el SELECT reportado contra MySQL mediante el flujo de trabajo de CI. Se considera terminado cuando la ejecución de pruebas de MySQL ya no informe de un error de sintaxis para esta consulta de ActiveRelationResource.
