Rails - Inherited Resource - missing template in one environment only

Question

Question as above - I'm trying to create a new booking which happens fine in development, however the same code on the staging server gives me:

ActionView::MissingTemplatebooking_system/bookings#new
Missing template booking_system/bookings/new, booking_system/base/new, inherited_resources/base/new, application/new with {:locale=>[:en], :formats=>[:html].....

I can see it's trying to look for a template in the inherited resources folder but not finding one... I've googled and can't find anyone with a similar issue.. my controller code if its needed:

module BookingSystem
  class BaseController < InheritedResources::Base
  end
end

module BookingSystem
  class BookingsController < BaseController
     authorize_resource
  end
end

Any help is greatly appreciated
