無法轉換爲長整數字符串 - 設計/會話控制問題

所以這是錯誤我看到：無法轉換爲長整數字符串 - 設計/會話控制問題

TypeError in Devise/sessionsController#create 

can't convert Fixnum into String 

Application Trace | Framework Trace | Full Trace 
app/controllers/application_controller.rb:21:in `set_current_user'

這是怎麼application_controller.rb外觀：

class ApplicationController < ActionController::Base 
    helper :all 
    helper_method :current_user, :logged_in? 

    protect_from_forgery 
    before_filter :set_current_user 

    def set_xhr_flash 
    flash.discard if request.xhr? 
    end 

    def correct_safari_and_ie_accept_headers 
    ajax_request_types = ['text/javascript', 'application/json', 'text/xml'] 
    request.accepts.sort! { |x, y| ajax_request_types.include?(y.to_s) ? 1 : -1 } if request.xhr? 
    end 


    protected 

    def set_current_user 
    Authorization.current_user = current_user 
    end 

end

幫助！

編輯1：根據請求，這裏是日誌文件的輸出。

任何人都想出任何解決方案嗎？

在set_current_user中，您可以在`Authorization.current_user = current_user`之前添加`logger.info current_user.inspect`並將日誌文件中的輸出追加到您的問題中？ – 2011-01-19 21:37:14

@Brett Bender完成。查看更新的問題。 – marcamillion 2011-01-19 22:09:48

奇怪的是，該記錄器調用的輸出出現在SessionsController＃new中爲nil（這是正確的，如果他們沒有登錄，沒有當前用戶），但是POST請求中沒有輸出來自該記錄器調用SessionsController＃create - 也許set_current_user沒有在那裏被調用？我會嘗試從錯誤發送到SessionsController＃create的錯誤消息之前得到一些調試輸出 - 顯然#new行動正如你所期望的那樣工作。希望我可以幫助更多。 – 2011-01-20 17:17:56

好，於是我終於找到了答案。數據庫損壞了。一旦我傾倒了整個數據庫，刪除了數據庫文件並重新創建了所有內容 - 我很樂意去。

嘆息

我只是希望我能想出一個辦法，以防止在生產發生。

你確定以下是在你正確的whatever_controller.rb中嗎？

before_filter :authenticate_user!

您是否將數據庫密碼設置爲純數字？我的數據庫密碼是111111在開發機器，根據錯誤信息"can't convert Fixnum into String"，我想我應該更改數據庫密碼爲非數字「abcdef」，它的工作！
