我們可以申請衝浪應用程序

Question

現在我正在處理從這裏衝來http://shopify.github.io/dashing/我創建了一個使用Sinatra的衝刺應用程序，我添加了一些更多的第三方API的一切工作正常。現在我想用rails來運行應用程序我試過每件事情都很好，但「事件」方法不能被服務器調用。實際上它在我的lib目錄下的dashing.rb文件中，就像這樣。

require 'sinatra' 
    ``require 'sprockets' 
    require 'sinatra/content_for' 
    require 'rufus/scheduler' 
    require 'coffee-script' 
    require 'sass' 
    require 'json' 
    require 'pry' 

module Dashing 
    SCHEDULER = Rufus::Scheduler.start_new 

    class App < Sinatra::Base 
    if Rails && Rails.root 
     set :root, Rails.root 
     set :root_path, '/dashing/' 



     Rails.application.config.assets.precompile += %w(dashing/application.js dashing/application.css) 
     set :views, Rails.root.join('app', 'dashing', 'dashboards') 
     set :widget_path, "#{settings.root}/app/dashing/widgets/" 

     set :lock, true 
     set :threaded, true 
    else 
     set :root, Dir.pwd 
     set :root_path, '/' 

     set :sprockets,  Sprockets::Environment.new(settings.root) 
     set :assets_prefix, '/assets' 
     set :digest_assets, false 
     ['assets/javascripts', 'assets/stylesheets', 'assets/fonts', 'assets/images', 'widgets', File.expand_path('../../javascripts', __FILE__)]. each do |path| 
     settings.sprockets.append_path path 
     end 

     set server: 'thin' 
     set :public_folder, File.join(settings.root, 'public') 
     set :views, File.join(settings.root, 'dashboards') 
     set :widget_path, File.join(settings.root, 'widgets') 
    end 

    set connections: [], history: {} 
    set :default_dashboard, nil 
    set :auth_token, nil 

    helpers Sinatra::ContentFor 
    helpers do 
     def protected! 
     # override with auth logic 
     end 
    end 

    get '/events', provides: 'text/event-stream' do 
     protected! 
     stream :keep_open do |out| 
     settings.connections << out 
     out << self.latest_events 
     out.callback { settings.connections.delete(out) } 
     end 
    end 

    get '/' do 
     begin 
     redirect settings.root_path + (settings.default_dashboard || self.first_dashboard).to_s 
     rescue NoMethodError => e 
     raise Exception.new("There are no dashboards in your dashboard directory.") 
     end 
    end 

    get '/:dashboard' do 
     protected! 
     erb params[:dashboard].to_sym 
    end 

    get '/views/:widget?.html' do 
     protected! 
     widget = params[:widget] 
     send_file File.join(settings.widget_path, widget, "#{widget}.html") 
    end 

    post '/widgets/:id' do 
     request.body.rewind 
     body = JSON.parse(request.body.read) 
     auth_token = body.delete("auth_token") 
     if !settings.auth_token || settings.auth_token == auth_token 
     Dashing::Application.send_event(params['id'], body) 
     204 # response without entity body 
     else 
     status 401 
     "Invalid API key\n" 
     end 
    end 

    class << self 
     def development? 
     ENV['RACK_ENV'] == 'development' 
     end 

     def production? 
     ENV['RACK_ENV'] == 'production' 
     end 

     def send_event(id, body) 
     body["id"] = id 
     body["updatedAt"] = Time.now.to_i 
     event = format_event(body.to_json) 
     settings.history[id] = event 
     settings.connections.each { |out| out << event } 
     end 

     def format_event(body) 
     "data: #{body}\n\n" 
     end 
    end 

     def latest_events 
     settings.history.inject("") do |str, (id, body)| 
      str << body 
     end 
     end 


    def first_dashboard 
     files = Dir[File.join(settings.views, '*.erb')].collect { |f| f.match(/(\w*).erb/)[1] } 
     files -= ['layout'] 
     files.first 
    end 

    Dir[File.join(settings.root, 'lib', '**', '*.rb')].each {|file| require file } 
    {}.to_json # Forces your json codec to initialize (in the event that it is lazily loaded). Does this before job threads start. 

    job_path = ENV["JOB_PATH"] || 'jobs' 
    files = Dir[File.join(settings.root, job_path, '/*.rb')] 
    files.each { |job| require(job) } 
    end 
end 

Rails無法執行/事件根在這個。

任何人都可以建議我。如何在rails中調用這個/ events根目錄。我使用batman.js來調用事件。
