Serializer not emitting JSON API spec

[kjs3]

Expected:

In Rails, when configured with ActiveModelSerializers.config.adapter = :json_api

I expected using ArticleSimpleSerializer.new(article).as_json (or .to_json) outside of a controller to emit JSON in JSON API format including data, type, and attributes root keys.

Actual:

I get JSON object with Serializer attributes. Essentially what I would have expected in
json["data"]["attributes"]

Steps to reproduce

I have a serializer for an Article model but named ArticleSimpleSerializer so automatic lookup with…

ActiveModelSerializers::SerializableResource.new(article)

… doesn't work.

Rendering in a controller does emit JSON API format.

render status: :ok, json: @article, serializer: ArticleSimpleSerializer

I can't seem to get this same output outside of a controller.

Environment

ActiveModelSerializers Version 0.10.2:

ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-darwin15]:

Mac OS 10.11.5

Rails 4.2

SerializableResource will take all the render options, so you can pass the serializer to it :-)

Lemme know if that changes anything :-)

Thanks @NullVoxPopuli!

ActiveModelSerializers::SerializableResource.new(article, serializer: ArticleSimpleSerializer).as_json

works perfectly.

Are you interested in a PR that spells this out in the docs?

yeah, it looks like https://github.com/rails-api/active_model_serializers/blob/master/docs/howto/outside_controller_use.md doesn't say what can be in options :-)
