Naw, don’t believe preloading is it since it works when you call it explicitly. Will have to dig into render to use the each_serializer option. Happy to consider PRs
There is also an option for :show method where you can serialize a single resource by calling render json: client, serializer: ClientSerializer
This isn’t working either. So I think it is related and not limited to each_serializer option.
Although as we are able to call it explicitly and it is working, anyone trying and arriving here should be able to continue.
