Jinja、NDB、およびWTFormsを使用してこの認証モジュールをwebapp2フレームワークで動作させるために、私は何週間も頭を悩ませてきました。私はどこでもオンラインで調べて、私の限界点に達しました、そして助けのために誰かに手を差し伸べる必要があります。私はこのチュートリアルに従っています（これはかなり徹底的ですが、特に私のような初心者にとっては、いくつかの重要な詳細が省略されていると思います）：
Webapp2 + GoogleAppEngineのユーザーアカウント
私が知る限り、すべてが正しくセットアップされていますが、継続的に404を取得します-リソースが見つかりません。何が間違っているのでしょうか？これが私のコードです...

<p>The whole idea here is to show how to set up a simple static web site
on Google App Engine. I want to create an easy way to host your modest web
site on App Engine. My approach is dead simple. All I use is some boilerplate
code almost anyone can follow. You can have multiple pages and use template
variable features that are part of App Engine's WebApp Framework. Most modest
web sites don't do much more than this. Your certainly free to expand on what
you find here.</p>""",
