Can we apply dashing for rails application - ruby-on-rails

Question

Now I am dealing with dashing from here http://shopify.github.io/dashing/ I created an dashing app using Sinatra and I added some more 3rd party API's everything is working well. Now I want to run the app with rails I tried every thing is working fine but "event" method can't be called by server.Actually it is in dashing.rb file in my lib directory it is like this.
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
