jsonapi.org and custom vendor content type

[igas]

Hi. According to spec http://jsonapi.org/format/#content-negotiation Content Negotiation part, I must use application/vnd.api+json.

If I do:

content_type :jsonapi, "application/vnd.api+json"
formatter :jsonapi, -> (object, _env) { Oj.dump(object) }

It return 406 cause try to use json. I found 3409da5 where vendor part drops. Is there any reason to do this?

From my point of view formatter should only format data, but it also overwrite content type but it is here.

Current implementation https://github.com/ruby-grape/grape/blob/master/lib/grape/middleware/formatter.rb#L170 & https://github.com/ruby-grape/grape/blob/master/lib/grape/middleware/formatter.rb#L122

Do I miss something?

You need to tell Grape which format to use, so format :jsonapi I think will do it?

Bring it up to the mailing list if you're still having problems, I'll close this here.
