從foreverb守護進程訪問我的模型

Question

我在foreverb守護進程上訪問我的可用性模型時有以下代碼。但我總是得到以下錯誤：

uninitialized constant Availability 

這裏是我的守護：

#!/usr/bin/ruby 
require 'rubygems' unless defined?(Gem) 
require 'forever' 
require 'mongoid' 

Forever.run do 

    every 10.seconds do 
    @classes = Availability.where(:availability_date.gt => Time.now.utc + 1.hours).to_a 
    puts @classes.count 
    end 

end 

感謝您的幫助。

注：我正在使用rails3和mongoid。

更新的代碼

---

#!/usr/bin/env ruby 
require 'rubygems' unless defined?(Gem) 
require 'forever' 
require 'mongoid' 

require File.expand_path('../config/environment', __FILE__) 

Forever.run do 

    every 10.seconds do 
     @classes = Availability.where(:availability_date.gt => Time.now.utc + 1.hours).to_a 
     puts @classes.count 
    end 

end 

現在我發現了以下錯誤：

用戶/ classes_notification.rb; tail -f -n 150 user/sample.log;

/Users/jeanosorio/.rvm/rubies/ruby-1.9.3-p484/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:126:in `require': cannot load such file -- /Users/jeanosorio/repos/blabloo/script/user/config/environment (LoadError)

    from user/classes_notification.rb:6:in `<main>' 

UPDATE

UPDATE PATH

---

#!/usr/bin/env ruby 
require 'rubygems' unless defined?(Gem) 
require 'forever' 
require 'mongoid' 

# Load Rails 
#ENV['RAILS_ENV'] = ARGV[0] || 'development' 

require File.expand_path('../../../config/environment', __FILE__) 

Forever.run do 

    every 10.seconds do 
     @classes = Availability.where(:availability_date.gt => Time.now.utc + 1.hours).to_a 
     puts @classes.count 
    end 

end 

現在我得到這個eror：

Answer 1

這是很容易負載Rails ENV只需添加到您的腳本的頂部：

#!/usr/bin/env ruby 

require File.expand_path('../config/environment', __FILE__) 

在Rails.root DIR工作這麼簡單的3行腳本。
