从foreverb守护进程访问我的模型

Question

我在foreverb守护程序上有以下代码来访问我的可用性模型。但我总是得到以下错误：

uninitialized constant Availability

这是我的守护进程：

#!/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

感谢您的帮助。

注意：我使用的是rails3和mongoid。

更新代码

#!/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

现在我收到以下错误：

用户/ 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>'

更新路径

#!/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

现在我得到了这个错误：

Answer 1

这非常容易加载Rails env只需添加到脚本顶部：

#!/usr/bin/env ruby

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

在Rails.root目录中使用这个简单的3行脚本。
