这是我的剥离代码 –

lib\taks\autoscrape.rake:
 desc "This task will scrape all the movies without info"
  task(:autoscrape => :environment) do
    require 'application'  #probably extraneous
    require File.dirname(__FILE__) + '/../../config/environment' #probably extraneous
    unless ApplicationController.is_admin?
      logger.error = "Sorry,you're not allowed to do that"
      return
    end


app\controller\application_controller.rb:
class ApplicationController < ActionController::Base
  helper :all # include all helpers,all the time

  def is_admin?
        session[:is_admin] && session[:is_admin] > 0
  end
end

result:
rake scrape:autoscrape --trace
** Invoke scrape:autoscrape (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute scrape:autoscrape
rake aborted!
undefined method `is_admin?' for ApplicationController:Class
E:/DropBox/My DropBox/Ruby/moviecat/lib/tasks/autoscrape.rake:11

我的其他控制器一直调用这段代码,没问题.我的Rake任务如何调用此代码？这大大简化了,它是一个更大问题的一部分,我想重用更多的代码.

谢谢！！
