Hi! Thanks for your PR :)

I had an error

Could you clarify a bit? I'd need to know what the exact error was so I could figure out what this code is fixing. Ideally, I'd like to get a spec case to avoid a similar error from happening in the future, so knowing what error this fixes is crucial 😄

Yes sure!
So let's say we have two JSONAPI::Resources like this:

module Api::V1
  class UserResource < BaseResource
    has_one :profile
  end
end


module Api::V1
  class ProfileResource < BaseResource
    has_one :user
  end
end

If I try to call the following endpoint:
localhost:3000/api/v1/profiles/XXXXXXXXX/relationships/user
or this one
localhost:3000/api/v1/profiles/XXXXXXXXX/user

I get the following exception:

"exception": "undefined method `user' for #<Api::V1::ProfileResource:0x00000006265ec0>",
                "backtrace": [
                    "/home/clement/.rvm/gems/ruby-2.4.1/bundler/gems/jsonapi-authorization-24bfed7949a3/lib/jsonapi/authorization/authorizing_processor.rb:75:in `public_send'",

I hope my example makes sense? Do not hesitate if you need me to clarify

Hmm, can you tell me what version of jsonapi-resources you are using? And what version of jsonapi-authorization?

I'm on both master branches:

• jsonapi-resources master@19f4d7b
• jsonapi-authorization master@24bfed7

OK, that makes sense. We do not yet support the upcoming jsonapi-resources v0.10 (see #64), so could you try downgrading jsonapi-resources to 0.9.0 and see if your error goes away?

Damn, sorry about that... Yes the errors goes away in the previous version!

Yess, great to hear that! I'm gonna close this issue, and add a link to #64 to notice that there will be trouble heading down this road :)
