私のコードは次のとおりです。

require 'bundler/setup'
require 'sinatra/base'
require 'jdbc/postgres'
require 'sequel'
require 'logger'
require 'json'
require 'sinatra/reloader'

class DemoApiApp < Sinatra::Application
  #set :show_exceptions, false

  configure :development do
    register Sinatra::Reloader
  end

  #connect to the database
  DB ||= Sequel.connect(ENV['data_source'])
  #DB2 ||= Sequel.connect(ENV['data_source_2'])
  #Sequel::Model.db = DB2
  #DB.loggers << $logger if $logger
  #DB.log_warn_duration = 2 #0.2
  #DB.sql_log_level = :debug

  set :views, 'views/demo_api/'

  get'/api_docs' do
    @nav_title = "API Documentation"
    @title = "API Documentation"
    @css ="dental"
    @dir ="api_docs"
    erb :demo_api_layout
  end

  get'/?' do
    @nav_title = "Plan A Member Portal - Medical"
    @title = "Medical Cost Estimator"
    @css = "medical"
    @dir = "medical/demo_api_index"
    @main_color = "2E57A1"
    @secondary_color = "353EA8"
    @txt_color = "0F2F69"
    @focus_color = "7E9BD0"
    @deductible = 5000
    @zip = 12211
    @proc = 33010
    @in_charge = 50
    @in_reimburse = 0
    @common_conditions = [{"key"=>"workbook", "description"=>"Cost Profile", "procs"=>[ ["33010"], ["93000"], ["80061"] ]}]
    erb :demo_api_layout
  end

end


# Dir.glob(File.expand_path(File.dirname(__FILE__)) + '/{helpers,controllers,models}/*.rb'). each { | file | require file }

require 'demo_api_controller'
# require 'models'

end

サイトにアクセスすると、空白のページが表示されます。何か助けはありますか？
