has_one :giver, class_name: '::Contractor'

[cs3b]

doesn't look for resources in the main namespace

class Mm::KudoResource < JSONAPI::Resource
  model_name 'Mm::Kudo'
  attributes :value, :tags, :comment

  has_one :giver, class_name: '::Contractor'
end````

I've got error 

```` bash
NameError: JSONAPI: Could not find resource 'mm//contractors'. (Class Mm::::ContractorResource not found)

how should I define that the relation is in the top level namespace?

I'm having the same issue. The only workaround is to add another instance of the ContractorResource, per this example. I.e. you'd have to add:

module Mm
  class ContractorResource < ::ContractorResource
  end
end

This is really unfortunate for pretty clear reasons, e.g. you can have disparate functionality in these two classes. Could a possible solution be to add a resource_name option on relationships similar to the current class_name option?

Hi there,

Working with the master branch here as we need the serialize_to_hash back. This issue also happens, with class_name not being used.

This seems to come from JoinManager#add_source_relationship which seems to be ignoring the class_name option and thus trying to compute the class name of the resource on its own.

This appears to be a regression in 0.10.x--I don't have this issue in 0.9.12. After upgrading, I'm forced to specify the class_name on the has_one, which is a non-starter for me because it's being invoked via the parent class, and I can't pass options.
