Websocket class override fails in production

[Bijendra]

I have to patch the below code in the gem,

app/controllers/websocket_rails/delegation_controller.rb

 module WebsocketRails
    class DelegationController < ApplicationController
    end
 end

Current project structure is like

  Project folder
      |_namespace1-/app/../application_controller.rb
      |_namespace2-/app/../application_controller.rb

So i have to override the default access in delegation_controller.rb.

  Project folder
     |_config/initializers/websocket_patch.rb

  module WebsocketRails
    class DelegationController < Namespace1::ApplicationController
    end
  end

This works properly in development environment but breaks in production. There is not specific configuration to load the initializers in production enviroment.

websocket-rails-0.7.0/lib/rails/app/controllers/websocket_rails/delegation_controller.rb:11:in 
`<module:WebsocketRails>': uninitialized constant WebsocketRails::ApplicationController (NameError)

I have tried multiple options to load forcefully but no luck. It still goes to the gem file path.
