errors when "Rendering from render"

[ak47]

the issue appears with the includes in the controller

class Api::V2::AppointmentsController 
in my rspecs, I consistently get:

Failure/Error: get "/api/v2/appointments/123"
     ActionController::RoutingError:
       undefined method `responder=' for Api::V2::AppointmentsController:Class
     # ./app/controllers/api/v2/appointments_controller.rb:2:in`include'

AND

 Failure/Error: get "/api/v2/appointments/#{@appointment.id}"
     AbstractController::ActionNotFound:
       The action 'show' could not be found for Api::V2::AppointmentsController

When remove those includes and use the alternative:

render json: AppointmentRepresenter.new(@appointment).to_json, status: :ok'

this works out as expected
Am I doing something wrong?
Ruby 2.1.2
Rails 4.1.5
Rspec 3.1.0
thanks

I remember this problem from a while ago (undefined method responder=') but thought we had it fixed. Can you find out where in Rails 4.1 the #responder= method is defined?

Does that help? https://github.com/apotonick/roar-rails/issues/87
