My Pyramid アプリは、貼り付け httpserver 内で実行すると正常に動作しますが、Google アプリ エンジンで例外がスローされます。

/hello/{name} URL は、貼り付けサーバーとアプリ エンジンの両方で正常に機能します

/test URL は貼り付けサーバーでは正常に機能しますが、アプリ エンジンでは以下のトレースバックが表示されます。

何か案は？

from pyramid.config import Configurator
from pyramid.response import Response

def hello_world(request):
    return Response('Hello %(name)s!' % request.matchdict)

def test(request):
    return dict()

settings = {'mako.directories':'mako_templates'}
config = Configurator(settings=settings)
config.add_route('hello', '/hello/{name}')
config.add_route('test', '/test', view=test, renderer='test.mako')
config.add_view(hello_world, route_name='hello')

wsgi_app = config.make_wsgi_app()

Google アプリ エンジンからのトレースバック:

この件に関する私の背景はかなり浅いので、これは間違っているかもしれません。

これが私の見解です: ピラミッドで mako を使用するには、mako テンプレート ディレクトリを指す「mako.directories」というキーを持つ設定ディクショナリを Configurator に与える必要があります。このキーは、相対パスまたは絶対パスのいずれかです。

pyramid/mako_templating.py ファイルは、次の行で相対パスを絶対パスに変換します。

directories = [ abspath_from_asset_spec(d) for d in directories ]

この変換は gae では機能しません (スタック トレースを参照)。これを回避するために、次のように Pyramid AssetResolver を使用しました。

from pyramid.path import AssetResolver
r = AssetResolver('appname')
full_mako_path = r.resolve('http/mako_templates').abspath()

次に、Pyramid Configurator を作成するときに、次のことを行います。

settings = {'mako.directories':full_mako_path}
config = Configurator(settings=settings)

この場合、私のディレクトリ構造は次のとおりです。

/serve.py (contains wsgi app)
/app.yaml
/appname
/appname/http/mako_templates
...

これを試して：

PyramidフォルダーとMakoフォルダーを、アプリ ディレクトリで指定されたディレクトリに配置します。次に、これらのコード行をインポートの下のメイン ファイルに追加します。framework.py

import sys, os
framework_dir = "framework"
framework_dir_path = os.path.join(os.path.dirname(__file__), framework_dir)
sys.path.insert(0, framework_dir_path)
