respond_with having issue with Rails 5 - ruby-on-rails

Question

I am upgrading my Rails app from 4.1.1 to 5.1.4.
I am using roar-rails gem to parsing and rendering REST documents. I am facing some issues as responders gem has been extracted to separate gem.
respond_with has been moved to 'responders' gem.
My rails 4 code lookgs like this:
PostsController:
class PostsController < ApplicationController
respond_to :json
def index
posts = current_user.posts
respond_with posts, :represent_with => PostsRepresenter, current_user: current_user
end
end
My representers for Post
module PostsRepresenter
# Rails 4 code
# include Roar::Representer::JSON::HAL
# Rails 5 code (after adding responders) --------
include Roar::JSON
include Roar::Hypermedia
# Rails 5 code --------
collection(
:post,
class: Post,
extend: PostRepresenter,
embedded: true)
link :make do |args|
p "............. #{args.inspect}"
# In rails 4, args are coming correctly what is passing from Controller
# But in rails 5, args is coming `nil`
posts_path if args[:current_user].can_create?(Post)
end
end
Post representer
module PostRepresenter
# Rails 4 code
# include Roar::Representer::JSON::HAL
# Rails 5 code (after adding responders) --------
include Roar::JSON
include Roar::Hypermedia
# Rails 5 code --------
property :title
property :description
property :author
link :self do |args|
post_path(id) if args[:current_user].can_read?(self)
end
link :remove do |args|
post_path(id) if args[:current_user].can_delete?(self)
end
link :edit do |args|
post_path(id) if args[:current_user].can_update?(self)
end
end
I am facing issue with args which are passing through Controller,
after rails 5, its coming nil.
I have debug the issue and found that in responders gem, options are coming in respond_with method, but I think it could not send it to roar-rails.
/path-to-gem/vendor/responders-master/lib/action_controller/respond_with.rb
Here is snippet:
def respond_with(*resources, &block)
if self.class.mimes_for_respond_to.empty?
raise "In order to use respond_with, first you need to declare the " \
"formats your controller responds to in the class level."
end
mimes = collect_mimes_from_class_level
collector = ActionController::MimeResponds::Collector.new(mimes, request.variant)
block.call(collector) if block_given?
if format = collector.negotiate_format(request)
_process_format(format)
options = resources.size == 1 ? {} : resources.extract_options!
options = options.clone
options[:default_response] = collector.response
p "====================== options :: #{options.inspect}"
# Options are correct till here but coming `nil` on representers
(options.delete(:responder) || self.class.responder).call(self, resources, options)
else
raise ActionController::UnknownFormat
end
end
Please let me know what needs to be done here that make args
available in representers

respond_with was deprecated from rails 4.2.1.
