エラーを解決することに加えて、私はまた、レンダリングを変更しています_to_responseメソッドは古いDjangoライブラリの問題ごとにレンダリングしますが、未定義のレンダリングのためにNameErrorがポップアップします!!

Answer 1

render_to_responseに電話する方法については、docsを参照してください。署名があるジャンゴの新しいバージョンでは、：

render_to_response(template_name, context=None, content_type=None, status=None, using=None) 

有効な引数...あなたはジャンゴのどのバージョンを使用していないcontext_instance=RequestContext(request)を渡していますか？
