Ruby on Rails 2.3.8：params在before_filter中是未定義的？

Question

before_filter :only => :destroy do |controller| 
     controller.is_object_on_same_account_as_current_account_for_id?(controller_name.classify.constantize, params[:id]) 
    end 

生成錯誤：

NameError: undefined local variable or method `params' 
app/controller/controller:4 

我認爲PARAMS總是可用的整個請求過程... = \

Answer 1

嘗試因爲paramscontroller.params[:id]被用於控制器定義。

Answer 2

嘗試request.params [：ID]或controller.request.params [：ID]這種變化在3.2.9工作對我來說
