status tab not displayed in ui (resque-status)

I am using resque status. In my Gemfile I have

gem 'resque-status'

In resque_conf.rb I have

require 'resque/status_server'

And I open the ui of resque using

resque-web ~/resque_conf.rb

In resque.rb I have

 require 'resque/job_with_status'

config = YAML::load(File.open("#{Rails.root}/config/redis.ym开发者_StackOverflow中文版l"))[Rails.env]
Resque.redis = Redis.new(:host => config['host'], :port => config['port'])

Resque::Status.expire_in = (24 * 60 * 60) # 24hrs in seconds

I don't know what I am missing here. When I first set up the resque-status the tab "Statuses" was being displayed but now after about a month it does not show the "Statuses" tab. Anyone got idea about it?

move require 'resque/status_server' from resque_conf.rb to resque.rb

# config/initializers/resque.rb
require 'resque/status_server'
require 'resque/job_with_status'
... 

Now, fire > resque-web and you'll get Statuses tab.
