unable to integrate open_id_authentication with ActionController::API - ruby-on-rails

Question

I am buidling rails application with my ApplicationController building on ActionController::API. I tried integrating open_id_authentication gem and it worked fine if my ApplicationController was built using ActionController::Base but threw error with API. I tried including middleware in following manners
Method 1. Add middleware in initilaizer
`config/initializers/openid.rb`
require 'open_id_authentication'
Rails.application.config do
config.middleware.use OpenIdAuthentication
config.after_initialize do
OpenID::Util.logger = Rails.logger
ActionController::API.send :include, OpenIdAuthentication::ControllerMethods
end
end
but got following error stack with it:
NoMethodError - undefined method `authenticate_with_open_id' for #:

Method 2. Add middleware via config/environment/development.rb
require 'open_id_authentication'
Rails.application.configure do
config.middleware.use OpenIdAuthentication::Middleware
end
It gave the same error stack
Please help me with the solution to include middleware for open_id_authentication in ActionController::API

Answer 1

I checked the middlewares included using command rake middleware and I found that OpenIdAuthentication::Middleware was already included. Going through rails-api README, I added config.middleware.use Rack::MethodOverride to config/environments/development.rb.
Now, to access open_id_authentication gem methods, include it in whichever module/controller you are using via include OpenIdAuthentication::ControllerMethods as ControllerMethods module has all the methods being used.
