ruby - 如何将此 Controller 代码移动到 Resque 作业？

Question

我想将我的一些 session Controller 进程移动到 Resque 工作程序中，以使登录更加顺畅。我想从这里移动零件:

def create  
  auth = request.env["omniauth.auth"]
  omniauth = request.env["omniauth.auth"]
  user = User.find_by_provider_and_uid(auth["provider"], auth["uid"]) || User.create_with_omniauth(auth,omniauth)     

  session[:user_id] = user.id  
  session['fb_auth'] = request.env['omniauth.auth']
  session['fb_access_token'] = omniauth['credentials']['token']
  session['fb_error'] = nil

  @graph = Koala::Facebook::GraphAPI.new(current_user.token)
  current_user.profile = @graph.get_object("me")
  current_user.likes = @graph.get_connections("me", "likes")
  current_user.friends = @graph.get_connections("me", "friends")
  current_user.save
  redirect_to root_url 
end

进入 Resque worker(在/tasks 中吗？)

#ResqueFacebook.rb

require 'resque-retry'
Class FBResque
  def self.perform()
      @graph = Koala::Facebook::GraphAPI.new(current_user.token)
      current_user.profile = @graph.get_object("me")
      current_user.likes = @graph.get_connections("me", "likes")
      current_user.friends = @graph.get_connections("me", "friends")
      current_user.save
  end    
End

我要在 session Controller 中添加什么来初始化该辅助作业？此外，因为它不再存在于 session 中，所以 current_user 将是一个 nil 对象。这是否意味着 worker 中的代码必须在用户循环中的 for user 中？

我倾向于将它们放在 app/jobs/ 中，因为它在自动加载路径上，而 lib 往往更麻烦(尽管它完全有效) .

这应该足够了:

require 'resque-retry'

class FBConnectionsJob
  @queue = :fb_connections

  def self.perform(user_id)
    user = User.find(user_id)  
    graph = Koala::Facebook::GraphAPI.new(user.token)
    user.profile = graph.get_object("me")
    user.likes = graph.get_connections("me", "likes")
    user.friends = graph.get_connections("me", "friends")
    user.save
  end    
end


def create  
  auth = request.env["omniauth.auth"]
  omniauth = request.env["omniauth.auth"]
  user = User.find_by_provider_and_uid(auth["provider"], auth["uid"]) || User.create_with_omniauth(auth,omniauth)     

  session[:user_id] = user.id  
  session['fb_auth'] = request.env['omniauth.auth']
  session['fb_access_token'] = omniauth['credentials']['token']
  session['fb_error'] = nil

  Resque.enqueue(FBConnectionsJob, current_user.id)

  redirect_to root_url 
end

PS:为什么要用大写字母输入 Class 和 End？ o_O
