私の Sphinx ベースのドキュメントには、カスタムの Jinja2 テンプレートを含む特別なページがあります。このテンプレートのコンテキストとして、少しの Python コードで生成されたカスタム オブジェクトを渡したいと思います。(彼らはdatetime、一種のカレンダーです。) には、次のconf.pyようなものが含まれます。
import datetime
def add_index(app):
yield 'index', {'today': datetime.datetime.today()}, 'index.html'
def setup(app):
app.connect('html-collect-pages', add_index)
これはローカルでは問題なくビルドされますが、Read the Docs は JSON を使用してシリアル化しようとします。「非 JSON 対応」オブジェクトをテンプレートに渡す方法はありますか?
私が得る例外は次のとおりです。
