How to see absolute paths in swagger for sinatra (rswag)

Setup

    # Gemfile
    gem 'rspec-swag'


    # config.ru
    map '/orders' do 
    run Web::OrdersApp 
    end

    map '/admin/orders' do 
    run Web::AdminOrdersApp 
    end

    # rspec 
    describe OrdersApp, :vcr, type: :request do
      let(:described_class) { OrdersApp }

      path '/index' do
        get '' do
        ....
        end
      end 
    end

Problem

rspec-swag generates docs for /index, map is ignored.
So, it isn't possible to test API via Swagger web UI. I need /orders/index in docs.

How to change code in order to make Swagger docs usable?

Solution: use method.

It found here Architecture for a modular, component-based Sinatra Application

# config.ru
run App

# app.ru
class App < Sinatra::Base
  use OrdersApp
  use AdminOrdersApp
end

class OrdersApp < Sinatra::Base
  get '/orders'
end

class AdminOrdersApp < Admin::Base
  get '/admin/orders'
end
