fixtureをGoogleAppEngineのDataStoreテストで使う。json編
参考 Using Fixture To Test A Google App Engine Site
DataSetsをjson化するのにfixture.dataset.converterでdataset_to_jsonが提供されていたりもする。ただdate_created(auto_now_add=True)のようなフィールドはDataSetsで前もって値を指定できないので、ここでjson化したデータを、実際(date_createdの付いた)のjsonのレスポンスと比較しても同じにはならない。

Google App EngineでTwitter OAuthを使う。
自分のタイムラインを取得してtweetできるまでのサンプル。
参考
tweepyでtwitterの3-legged OAuth認証を試してみた(GoogleAppEngine)
コードのなかで使用しているsimple_cookieは
Google Cookbook – Google App Engine A simple Cookie class のもの。
注意する点は
Twitter application settingでcallback URLを正しく設定すること。
callback URLに127.0.0.1を指定しているからかもしれないけど、なにも入力しないと
TweepError: HTTP Error 401: Unauthorized になる。
tweepy
はapp engineのディレクトリにモジュールのディレクトリをコピーして使った。
以下サンプルコードと実行
