這裏是燒瓶蟒蛇：http://pastie.org/8712899錯誤500使用jQuery阿賈克斯獲得和瓶
，這裏是在index.html的模板中的HTML + JS：
的問題是，它的工作原理完全被通緝當通過內置的本地服務器運行時，但在使用apache wsgi部署時單擊搜索按鈕時會出現500錯誤。
它是在這裏在線（而不是功能） http://thekindlyone.scribblehead.info/calvinball/
幫助？
這裏是回溯的日誌。

更新：我設置絕對嗖的一聲索引目錄路徑，並以絕對的cnh.cbz路徑。但即使如此，我也得到了error。雖然whoosh索引的作品。是否因爲cnh.cbz文件位於flask應用程序目錄之外？我該如何解決？ 這裏是新的Python

更新2：我創建了cnh.cbz硬鏈接到燒瓶中的應用程序目錄和它的作品。 但是必須有更好的方法。
將堆棧跟蹤配置爲發送到基於apache的服務器上的日誌文件，這樣，當您遇到500錯誤時，您不會失明。如果您仍然無法理解錯誤，請在您的問題中添加堆棧跟蹤。 – Miguel
@Miguel我不能。當我嘗試登錄時，[This]（http://pastie.org/8714023）正在發生。 – thekindlyone
