Some, but not all, routes not available

I'm encountering a strange issue w/routing. I have the following
routes:
  namespace :consumer do
    resources :businesses, :only => :show do
      resources :events, :only => :show
    end
  end

  And I'm using a presenter object, so I have to manually include the
routes as such:
  include Rails.application.routes.url_helpers

  now I'm able to access consumer_business_path(some_business)
  but I can't use consumer_business_event_path(some_event).

I get the following error:
  ActionController::RoutingError Exception: No route matches
{:controller=>"consumer/events", :business_id=><SOME

, :action=>"show"}

What gives?

It’s expecting you to supply the business and the event. Since you’ve only supplied the event, it doesn’t know what to do
