Google應用引擎TypeError問題

Question

我在使用django的Google應用引擎上獲得了一個簡單的應用，而且我有兩個看起來幾乎完全相同的類，但其中一個類與TypeError崩潰。

Traceback (most recent call last): 
    File "C:\Program Files (x86)\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 3211, in _HandleRequest

TypeError: NotFoundPage() takes exactly 1 argument (0 given) 

我的類看起來像這樣（main.py）：

import os 
import datetime 

from google.appengine.ext import webapp 
from google.appengine.ext.webapp import template 
from google.appengine.ext.webapp.util import run_wsgi_app 

class BasePage(webapp.RequestHandler): 
    def initialize(self, request, response): 
     webapp.RequestHandler.initialize(self, request, response) 
     dir = os.path.join(os.path.dirname(__file__), "../templates") 
     self.template_path = os.path.abspath(dir) 

    def render_to_response(self, page, template_values): 
     page_path = os.path.join(self.template_path, page) 
     self.response.out.write(template.render(page_path, template_values)) 


class DefaultPage(BasePage): 
    def get(self): 
     visitor = Visitor() 
     visitor.ip = self.request.remote_addr 
     visitor.put() 

     page = Page() 
     page.title = "MY PORTAL" 
     page.subtitle = "Home" 
     page.name = self.request.path 

     visitors_query = Visitor.all().order('-added_on') 
     visitors = visitors_query.fetch(20) 

     self.render_to_response("main.html", 
     { 
      "page": page, 
      "visitors": visitors, 
     }) 


def NotFoundPage(BasePage): 
    def get(self): 
     page = Page() 
     page.title = "MY PORTAL" 
     page.subtitle = "Not Found" 
     page.name = self.request.path 

     self.render_to_response("empty.html", 
     { 
      "page": page, 
     }) 

application = webapp.WSGIApplication(
            [('/', DefaultPage), 
            ('/index.html', DefaultPage), 
            ('/.*', NotFoundPage), 
            ], 
            debug=True) 

def main(): 
    run_wsgi_app(application) 

if __name__ == "__main__": 
    main() 

當我去/index.html，一切都很完美。但是當我轉到/not-found.html時，它會因錯誤而崩潰。我無法弄清楚這個腳本有什麼問題。也許我忽略了一些東西。請幫忙。

Answer 1

def NotFoundPage(BasePage): 

應該是：

class NotFoundPage(BasePage):
