Removing /v1 from the links e.g. self in JSON results

I am using HTTP headers to add versioning capabilities in my API. I am accessing my API endpoint as such...
http://localhost:3000/api/posts
However, for the links in relationship like comments. It shows something like this...
http://localhost:3000/api/v1/posts/1/relationships/comments
What I want to do is to have this...
http://localhost:3000/api/posts/1/relationships/comments

I read the suggestion from #257 but I could not figure out where to put the monkey patch file (apologies for that.)

Thank you!

To monkey patch, you can create an initializer like this:

# config/initializers/jsonapi_resources_patch.rb

module JSONAPI
  class LinkBuilder
    def formatted_module_path_from_class(klass)
      '/api/'
    end
  end
end
