Broken support of ActiveModel resources in 0.10.x

Based on gem documentation it is possible to create some service for ActiveModel resource. In fact, it does not work anymore in 0.10.x

The gem documentation has to be updated on wiki https://github.com/cerebris/jsonapi-resources/wiki/Using-JSONAPI::Resources-with-non-ActiveRecord-models-and-service-objects

There is some code examples in tests, but they are very complicated for such simple task.

https://github.com/cerebris/jsonapi-resources/blob/master/test/fixtures/active_record.rb#L1545

Please provide a real working example. It is a pain in ass to hack the gem to provide simple API for non ActiveRecord resource. I have very simple use case: returning list of all timezones via API:

ActiveSupport::TimeZone.all.map { |z| [z.name, z.to_s] }

リンク先の wiki ページと、test/fixtures/active_record.rb:1545 周辺の ActiveModel 関連の例を読んでください。0.10.x でどの非 ActiveRecord リソースのセットアップが機能するかを確認し、サービスオブジェクトまたは ActiveModel リソース用の、よりシンプルで動作する例を、timezone-list のユースケースを含めて wiki に追加してください。
